MCP Server Catalog
Chapter 9 of Loop Engineering introduces MCP as the nervous-system layer of the architecture. The book defers the live catalog of MCP servers (which vendors implement what, with which capabilities) to this page because the half-life of that catalog is shorter than the print cycle.
The catalog scaffold below shows the structure each entry will follow once populated. Refreshed quarterly.
Catalog scaffold
Each MCP server entry carries:
- Vendor / project name, with link to the upstream MCP server repository or documentation.
- What it exposes: the capability or data source the server provides.
- Client compatibility: which AI assistants consume it (Claude Code, OpenAI Codex, Cursor, custom MCP clients).
- Verified date: when this entry was last confirmed against the upstream source.
- Notes: prompt-injection mitigations, authentication model, sandboxing posture where documented.
Initial seed list (to be filled)
Per Loop Engineering Appendix B and the launch announcement Introducing the Model Context Protocol:
- Block
- Apollo
- Zed
- Replit
- Codeium
- Sourcegraph
- Community MCP servers (growing inventory; will be grouped by capability category once populated)
This page is the entry point. The full catalog ships as Tier 1 content before the book's launch (see COMPANION-SITE-PLAN.md for the build order).
