Description

OAuth and authentication flows for MCP servers that require auth (Slack, Gmail, Google Calendar, Hugging Face, Similarweb, etc.). CC has McpAuthTool and OAuth port management (src/services/mcp/auth.ts, oauthPort.ts).

Current State

Babysitter's MCP server (mcp:serve) uses stdio transport with no auth. No MCP client auth. No OAuth flow support. Cannot connect to MCP servers that require authentication.

Target State

  • OAuth flow support for MCP server connections
  • Token storage and refresh
  • mcp:auth <server> CLI command for interactive auth
  • Headless auth support for CI/CD (token injection via env vars)
  • Auth state persisted in ~/.a5c/mcp-auth/

Recommendation

Phase 3. Needed for Slack/Gmail/Calendar MCP integrations. Implement OAuth code flow with PKCE. Store tokens encrypted in global state dir.
