RustAPI v0.1.501

Native MCP support! Your API is now an AI agent toolkit.

🚀 Highlights

• Full MCP (Model Context Protocol) support via the new rustapi-mcp crate

  • Automatically expose routes as tools using your existing OpenAPI spec

  • Tag-based filtering (allowed_tags) so agents only see what you want them to

  • Real proxied tools/call — every call goes through your normal middleware, extractors, validation, and error handling

  • Works great with Claude, Cursor, custom agents, etc.

• One-liner enablement

  .use_mcp(McpConfig::new().allowed_tags(vec!["public", "agent"]))

• Crate cleanup: Consolidated from 13 crates down to 9. rustapi-testing, jobs, view, and toon are now features instead of separate published crates.

• Better observability UX

  • Dashboard now has route filters + integrated replay browser

  • Improved replay admin API with pagination and filters
