+``` + +## Rust Backend Libraries + +### Core Components + +The Rust backend is divided into several key components: + +1. **mcp-guardian-core**: Core library implementing: + - Guard profile management + - Message interception + - Message approval + - Server collection management + - Core data models with Serialize/Deserialize/JsonSchema + +2. **mcp-guardian-schema**: Schema generation package for: + - Generating JSON Schema from core Rust types + - Providing validation rules for frontend components + - Exporting schemas for Monaco Editor integration + - Maintaining type consistency across the application + +3. **mcp-guardian-proxy**: Proxy implementation for: + - Intercepting messages to/from MCP servers + - Applying guard profiles + - Handling message routing + +4. **src-tauri/src**: Tauri command implementations: + - Bridging frontend to core libraries + - Exposing APIs via Tauri commands + - Managing application-specific state + +### Key Rust Modules + +#### Core Library +- `guard_profile.rs`: Defines guard profile data structures and operations +- `message_interceptor/`: Implements different interceptor types +- `message_approval.rs`: Handles manual approval flow +- `server_collection.rs`: Manages collections of servers with profiles + +#### Schema Package +- `lib.rs`: Main entry point and schema export functions +- `guard_profile_schema.rs`: Schema generation for guard profiles +- `mcp_server_schema.rs`: Schema generation for MCP servers +- `server_collection_schema.rs`: Schema generation for server collections +- `utils.rs`: Utility functions for schema generation and validation + +## Communication Flow + +### Frontend to Rust + +The frontend communicates with Rust backend via Tauri commands: + +```typescript +// Example: Frontend invoking Rust function +const updateGuardProfiles = () => invoke("list_guard_profiles", {}).then(setGuardProfiles); + +// Example: Frontend saving a guard profile +await invoke("set_guard_profile", { + namespace, + name, + guardProfile, +}); +``` + +### Rust Command Implementation + +Rust functions are exposed as Tauri commands: + +```rust +#[tauri::command] +pub async fn list_guard_profiles() -> Result> { + mcp_guardian_core::guard_profile::list_guard_profiles() + .map_err(|e| format!("list_guard_profiles() failed: {e}")) +} + +#[tauri::command] +pub async fn set_guard_profile( + namespace: &str, + name: &str, + guard_profile: GuardProfile, +) -> Result<()> { + mcp_guardian_core::guard_profile::save_guard_profile(namespace, name, &guard_profile) + .map_err(|e| format!("set_guard_profile(namespace={namespace}, name={name}, ..) failed: {e}")) +} +``` + +## Guard Profile Implementation + +### Data Model + +Guard profiles have a hierarchical structure: + +1. **GuardProfile**: Top-level structure containing a primary interceptor +2. **MessageInterceptorGuardConfig**: Enum of different interceptor types +3. **Specific Config Types**: Configuration for each interceptor type + +```rust +pub struct GuardProfile { + pub primary_message_interceptor: MessageInterceptorGuardConfig, +} + +pub enum MessageInterceptorGuardConfig { + Chain(chain::ChainGuardConfig), + Filter(filter::FilterGuardConfig), + MessageLog(message_log::MessageLogGuardConfig), + ManualApproval(manual_approval::ManualApprovalGuardConfig), +} +``` + +### Interceptor Types + +1. **Chain Interceptor**: + - Combines multiple interceptors in sequence + - Messages flow through each interceptor in order + - Structure: `ChainGuardConfig { chain: Vec }` + +2. **Filter Interceptor**: + - Applies conditional logic to messages + - Can match on direction, message type, or custom logic + - Structure: + ```rust + FilterGuardConfig { + filter_logic: FilterLogicGuardConfig, + match_action: FilterActionGuardConfig, + non_match_action: FilterActionGuardConfig, + } + ``` + +3. **Message Log Interceptor**: + - Logs messages at a specified level + - Structure: `MessageLogGuardConfig { log_level: String }` + +4. **Manual Approval Interceptor**: + - Queues messages for manual approval + - Structure: `ManualApprovalGuardConfig {}` + +### Current UI Implementation + +The current UI provides basic JSON editing: + +1. User creates/opens a guard profile +2. JSON representation is shown in a text editor +3. User manually edits the JSON +4. Configuration is validated and saved + +This approach is functional but requires technical knowledge and is error-prone, which is why Phase 4 UX improvements are needed. + +### Schema-enhanced JSON Editing (In Progress) + +As part of Phase 4, we're implementing schema-enhanced JSON editing: + +1. **Monaco Editor Integration**: + - Full-featured code editor with syntax highlighting + - Schema-based validation with error indicators + - Intellisense and autocompletion for properties + +2. **JSON Schema System**: + - Generated directly from Rust types using `schemars` + - Provides validation rules matching the backend data model + - Includes property descriptions and constraints + +3. **Improved Developer Experience**: + - Real-time validation feedback + - Property suggestions while typing + - Documentation tooltips + - Error highlighting with specific messages + +This approach maintains the flexibility of JSON editing while providing much better guidance and error prevention. + +## Message Handling + +### Message Flow + +1. **Interception**: Messages to/from MCP servers are intercepted by the proxy +2. **Guard Profile Application**: The appropriate guard profile is applied +3. **Chain Processing**: Messages flow through interceptor chain +4. **Potential Approval**: Messages may be queued for manual approval +5. **Final Disposition**: Messages are ultimately sent or dropped + +### Manual Approval + +The `ManualApprovalInterceptor` includes: + +1. **Message Queueing**: Adds messages to a pending approval queue +2. **Status Checking**: Periodically checks if message has been approved +3. **Continuation**: Proceeds or aborts based on approval decision + +The frontend polls for pending messages and displays them in the UI, allowing users to approve or deny. + +## Data Storage + +### File Storage + +Guard profiles are stored as JSON files: + +1. **Core Profiles**: Built-in profiles stored in code +2. **Custom Profiles**: User-created profiles stored as JSON files +3. **File Structure**: Organized by namespace and name + +``` +guard-profiles/ + namespace1/ + profile1.json + profile2.json + namespace2/ + profile3.json +``` + +### Schema System + +As of Phase 4, a dedicated JSON Schema system has been implemented: + +1. **mcp-guardian-schema Package**: + - Dedicated Rust package for schema generation + - Generates JSON Schema from Rust types using `schemars` + - CLI tool for generating and exporting schemas + +2. **Schema Generation**: + - All core types have `JsonSchema` derives + - Schemas stored in `/components/json-editor/schemas/` + - Includes validation rules based on Rust type definitions + +3. **Frontend Integration**: + - Schemas used for Monaco Editor validation + - Enables autocompletion and documentation tooltips + - Maintains single source of truth from Rust to frontend + +### Serialization + +1. **JSON Serialization**: Using `serde_json` for Rust<->JSON conversion +2. **TypeScript Generation**: Using `ts-rs` for Rust->TypeScript type generation +3. **Schema Generation**: Using `schemars` for Rust->JSON Schema generation +4. **Validation**: JSON Schema validation in editor, with basic validation on save/load + +## Implications for Phase 4 UX Improvements + +### Guard Profile Visual Builder Considerations + +1. **Data Model Compatibility**: + - Visual builder must generate valid `GuardProfile` structures + - All properties from Rust model must be represented + - Maintain compatibility with existing JSON schema + +2. **Two-way Synchronization**: + - Convert between visual representation and JSON data model + - Update visual diagram when JSON changes + - Update JSON when visual diagram changes + +3. **Interceptor Support**: + - Create custom node types for each interceptor variant + - Represent Chain interceptors as parent nodes with children + - Support complex filter logic combinations + - Provide appropriate property editors for each type + +4. **User Workflow Integration**: + - Visual builder should be the primary editing interface + - Maintain JSON editor as an advanced option + - Add templates and presets based on core profiles + - Provide validation feedback in the visual interface + +### Technical Implementation Approach + +1. **React Flow Integration**: + - Use React Flow (xyflow) for node-based editing + - Custom nodes for different interceptor types + - Custom edges for connecting interceptors + - Node property forms for interceptor configuration + +2. **Data Transformation**: + - Convert `GuardProfile` JSON to React Flow nodes/edges + - Convert React Flow nodes/edges back to `GuardProfile` JSON + - Maintain consistency with Rust data model + +3. **Schema Integration**: + - Use generated JSON Schema for validation + - Implement Monaco Editor with schema validation + - Provide intellisense and autocompletion based on schema + - Enable documentation tooltips from schema metadata + +4. **User Experience Enhancement**: + - Interactive drag-and-drop interface + - Visual feedback for validation issues + - Contextual help for different interceptor types + - Templates for common configurations + +By building on the existing architecture while introducing visual editing capabilities and schema-based validation, the Phase 4 UX improvements will significantly enhance the user experience while maintaining compatibility with the robust Rust backend implementation. The JSON Schema system provides a critical foundation for ensuring data integrity and improving developer experience. \ No newline at end of file diff --git a/_context_library/PHASE4_COMPONENTS.md b/_context_library/PHASE4_COMPONENTS.md new file mode 100644 index 0000000..d3db72f --- /dev/null +++ b/_context_library/PHASE4_COMPONENTS.md @@ -0,0 +1,467 @@ +# Phase 4 Component Analysis and Proposals + +This document contains detailed analysis of each major component in MCP Guardian and specific proposals for visual UI components to be implemented in Phase 4. + +## Current Component Architecture + +MCP Guardian has a modular component architecture with: + +1. **Page Components** - Main route pages (e.g., `guard-profiles-page.tsx`) +2. **Entity Components** - Components for specific entities (e.g., `guard-profile-component.tsx`) +3. **Shared UI Components** - Reusable UI elements in `/components/ui` +4. **Dialog Components** - Modal dialogs for creating/editing entities + +All components use a consistent styling approach with Tailwind CSS utilities and follow the app's design system. + +## Component Proposals for Phase 4 + +Based on the UX discovery analysis, here are specific component proposals for each core feature area. + +### 1.

The interface aims to be an intuitive extension of the user's analytical workflow, reducing cognitive load and enabling confident decision-making. diff --git a/_context_library/blog_posts/enterprise_announcement.txt b/_context_library/blog_posts/enterprise_announcement.txt new file mode 100644 index 0000000..63f7d85 --- /dev/null +++ b/_context_library/blog_posts/enterprise_announcement.txt @@ -0,0 +1,88 @@ +MCP Guardian: Essential Security for Agentic Tool Use +Fri 21 Feb 2025 +· +Written by: Cameron Fyfe - Lead Engineer, Michael Ramos - Head of AI +Share +MCP Guardian is a security and governance layer for AI assistants (agents) that use the Model Context Protocol (MCP). It provides real-time visibility and control over how large language models interact with external tools, data sources, and APIs. By functioning as a proxy between AI applications like Claude Desktop, Cursor IDE, and MCP servers, MCP Guardian delivers critical security capabilities: comprehensive activity logging, request approval workflows, and automated safety scanning. For organizations deploying AI systems that need privileged access to sensitive resources, MCP Guardian represents an essential control point—allowing security teams to govern and monitor AI actions, prevent unauthorized data access, and maintain compliance without sacrificing the productivity benefits of agentic AI workflows. + +MCP Guardian is open source under the Apache-2.0 license. + +EQTY Lab is building enterprise-grade agentic solutions with MCP and MCP Guardian that incorporate trust and verifiable governance. Reach out for more information. + +Model Context Protocol (MCP) +Model Context Protocol (MCP) solves a practical problem in enterprise AI deployment: standardizing how AI systems connect with organizational data and tools. Launched by Anthropic in November 2024, MCP provides a common interface for language models to access external resources like databases, file systems, and APIs. It functions as a standardized connector that eliminates the need to build custom integrations for each AI application and data source pairing. The rapid development of thousands of MCP-server implementations in just three months demonstrates MCP's utility in addressing real integration challenges – take a look at reference servers here. + +For enterprises deploying AI in production environments, MCP reduces development overhead while establishing consistent boundaries between AI assistants and corporate systems - a critical consideration for security-conscious organizations. + +Beyond Simple Automation: The Rise of Agentic AI Through MCP +MCP accelerates the practical implementation of agentic AI by providing the infrastructure these systems need to interact effectively with real-world tools. Unlike basic automation that follows fixed patterns, agentic workflows can plan, adapt, and coordinate activities across multiple systems while maintaining context. + +We're witnessing early signs of this evolution as AI assistants increasingly handle complex processes that previously required human coordination. Through MCP's standardized connections, AI systems can seamlessly access document repositories, manipulate data, control applications, and even coordinate with other specialized systems—all within coherent, goal-directed workflows. + +This transformation represents a significant step toward the potential of AI agents that can meaningfully assist with complex knowledge work. As these capabilities continue to expand, solutions like MCP Guardian ensure organizations can embrace agentic AI while maintaining appropriate governance and oversight. + +The Security Gap in AI Agent Deployments +As enterprises adopt Model Context Protocol (MCP) to connect AI Agents with critical systems, a significant security challenge emerges. While MCP solves integration problems, it also creates new attack vectors that security teams must address. When AI agents can access sensitive databases, manipulate files, or invoke API endpoints, organizations face several critical risks: + +Unmonitored Access: Without proper visibility, AI assistants could access or modify sensitive data without security teams' knowledge. A compromised prompt or malicious instruction could potentially extract confidential information through legitimate MCP connections. +Lack of Governance: Standard MCP implementations provide no built-in approval workflows, making it difficult to enforce "human-in-the-loop" requirements for sensitive operations like database modifications or financial transactions. +Limited Audit Trails: While MCP enables powerful connections, it doesn't inherently provide the comprehensive logging capabilities required for security investigations or compliance reporting. +Privilege Management Challenges: As organizations deploy multiple MCP servers with varying security requirements, managing appropriate access levels becomes increasingly complex. +MCP Guardian directly addresses these vulnerabilities by creating a security control plane between AI applications and MCP servers. Acting as a specialized proxy, it inspects all MCP traffic while providing real-time visibility, governance controls, and comprehensive audit logs. + +Key Security Benefits +MCP Guardian delivers several essential security capabilities for organizations deploying AI agents: + +Complete Activity Transparency: Security teams gain visibility into every resource access, tool invocation, and data request made through MCP connections. +Granular Request Controls: Administrators can implement approval workflows for sensitive operations, ensuring human oversight for critical actions. +Consolidated Audit Logging: All AI agent activities are logged in a standardized format, simplifying compliance reporting and security investigations. +Centralized Configuration Management: Security policies can be applied consistently across multiple AI assistants and MCP server connections. +Advanced Guardrailing: Protection evolves from simple pattern matching to sophisticated multi-layered defenses: + +>Rule-based filters prevent basic security violations through regex patterns and allow lists + +>ML-powered classification models detect anomalous request patterns and potential data exfiltration attempts + +>Security-focused AI agents can evaluate complex requests against organizational policies, adapting protection as threats evolve; including integration for third-party guardrails such as NVIDIA Nemo, or Protect AI LLM Guard. +By implementing MCP Guardian, organizations can confidently deploy AI agents with appropriate security guardrails. This enables security teams to maintain control while still allowing knowledge workers to benefit from AI-assisted workflows across multiple systems and data sources. + +How MCP Guardian Works +MCP Guardian functions as a transparent proxy that sits between AI assistants and MCP servers, monitoring and controlling all communication without requiring modifications to either component. By leveraging MCP's standardized protocol design, Guardian can provide security controls regardless of which AI application or server implementation is being used. + +The system is simple to deploy with today's popular AI tools. Organizations already using Claude Desktop or Cursor IDE can immediately benefit from Guardian's protection by configuring these clients to connect through the Guardian proxy rather than directly to MCP servers. This straightforward integration path allows security teams to implement controls without disrupting existing AI workflows. + +Under the hood, MCP Guardian is engineered for enterprise-scale deployment. The tool is built in Rust for performance and security. + +This architecture supports both simple desktop deployments and complex distributed environments where AI agents operate across multiple systems and data centers. As enterprise adoption of agentic AI accelerates, MCP Guardian's scalable design ensures security controls can grow alongside increasingly sophisticated AI deployments. + +Potential Applications: MCP Guardian in Enterprise Environments +Let's explore three scenarios showing how MCP Guardian could secure AI agents' tool interactions: + +1. Securing Claude Desktop Tool Access +When knowledge workers use Claude Desktop, MCP Guardian could monitor and protect: file system interactions, document processing APIs, database queries, and analytics platforms. In financial services, this means inspecting tool calls before reaching servers or sending data to Claude, blocking PII access, logging interactions, and enabling GLBA-compliant document analysis. + +2. Securing Cursor IDE Tool Integration +For development teams, MCP Guardian could secure access to Git repositories, code analysis tools, build systems, and package managers. This enables scanning code execution requests, blocking credential exposure, enforcing license compliance (e.g. Tools that pull in external repos), and protecting sensitive code while maintaining AI-assisted development capabilities. + +3. Securing Multi-System Enterprise Tools +For complex workflows, MCP Guardian could provide unified audit trails across MCP servers, consistent security policies, role-based approvals, and secure system integration. Organizations could monitor AI tool usage across ERP/CRM systems, maintain security boundaries, log interactions, and enable automation with control. + +These scenarios demonstrate how MCP Guardian acts as a security layer between AI platforms and their tools, enabling powerful automation while maintaining comprehensive oversight and controlled governance of tool usage. + +Agents Guarding Agents: The New Security Paradigm +As AI agents gain increasing capabilities and access privileges, we face an intriguing security paradox - using AI systems to protect against misuse by other AI systems. MCP Guardian enables an early step in this direction, leveraging AI capabilities as a security layer while maintaining human oversight. MCP Guardian itself is not an agent, but our roadmap includes the ability to integrate agents as guardrails. + +This approach acknowledges a pragmatic reality: as AI workflows grow more complex, traditional security methods alone become insufficient. The same pattern-recognition and contextual understanding that make language models powerful assistants can also make them effective guardians - able to evaluate complex requests against security policies in ways static rules cannot. + +We're still in the early stages of this security evolution. The concept of "agents guarding agents" introduces new challenges and dependencies that security professionals must carefully consider. Yet as AI systems become more deeply integrated into enterprise operations, this approach may become increasingly important - not replacing human security governance, but providing an essential layer of protection at the speed and scale that modern AI deployments demand. + +EQTY Lab Releases MCP Guardian +At EQTY Lab, we focus on developing verifiable integrity solutions for data and AI systems. We're pleased to announce our release of MCP Guardian to address emerging security challenges in enterprise AI deployments. As we build governance and provenance frameworks, we recognize both the transformative potential of agentic AI workflows and the critical need for appropriate security controls. + +MCP Guardian represents our strategic investment in the agentic era. We will continue developing this security layer and similar tooling as AI assistants gain increasing capabilities across enterprise systems. For organizations balancing innovation with security requirements, our solutions enable the productivity benefits of agentic AI while maintaining essential visibility, control, and compliance. + +Checkout MCP Guardian: +https://github.com/eqtylab/mcp-guardian + +EQTY Lab +MCP Guardian is open source under the Apache-2.0 license.
