Neel's Plugin Marketplace

A custom plugin marketplace for Claude Code and Anthropic Cowork — built and maintained by Indranil Banerjee.

All three plugins ship with zero global hooks and zero auto-connecting MCP servers as of May 2026, so they coexist cleanly with other plugins and don't pollute unrelated Claude Code work. All HTTP MCP connectors are Cowork-compatible.

🛡️ Compliance

All three plugins are designed to comply with the Anthropic Software Directory Policy:

• No financial transaction processing
• No advertising or ad-serving
• No circumvention of Claude safety guardrails

Plugin Coexistence Pattern

All three plugins follow a strict "no global side-effects" pattern as of May 2026:

• hooks/hooks.json ships as {"hooks":{}}. Plugin hooks fire globally on every Claude Code operation regardless of working directory, so embedding compliance/verification logic in hooks pollutes unrelated work. The work lives instead in agent files (where it runs in proper context) and Quality Gate criteria.
• .mcp.json ships as {"mcpServers":{}}. Plugin-bundled MCP servers auto-connect on plugin enable, which means shipping N servers triggers N connection attempts (and likely auth prompts) for users who only want some of them. Each plugin ships its full connector catalog as a .mcp.json.connectors-reference file with per-entry auth notes; users opt in via the plugin's connect skill.

If you contribute a plugin to this marketplace, please follow the same pattern.
