feat(examples): add mcp-server use case and gemini-cli updates#120
Conversation
Adds a runnable `mcp-server` recipe that attaches the public DeepWiki HTTP
MCP server to a session and verifies the agent can see/use it on both ACP
and Claude paths. Adds the scaffold plumbing required to support it and
brings the gemini-cli launch flags up to date.
- New `mcp-server` use case targeting DeepWiki HTTP MCP. ACP success is
observed via a `tool_call` whose identifier fields reference the server;
Claude success is observed via the per-turn `system/init` payload listing
`deepwiki` in `mcp_servers`.
- Scaffold support for two new `UseCase` fields:
- `acpMcpServers` — passed to `newSession` for ACP agents.
- `extraMountsByAgent` — appended to the standard
`agent_mount` / `broker_mount` pair, with `FileMount` and `ObjectMount`
types. Used to mount `~/.gemini/settings.json` inline because gemini-cli
reads MCP config from settings.json at startup and does not honour ACP
`newSession.mcpServers`.
- gemini-cli launch args updated to `--acp --yolo --skip-trust` to match
upstream's flag rename and so MCP tools are exposed in untrusted
workspaces.
- Regenerated `compatibility.md` and registered the new use case in
`llms.txt`.
