- Official MCP Registry · 8.17/10 for this job (curated estimate, high confidence)
The Official MCP Registry is the canonical open source-of-truth index that coding agents, IDEs, and MCP clients query to discover verified tool servers; pair with Cloudflare Workers to serve /.well-known/mcp/server.json, /llms.txt, and /AGENTS.md at the edge.
- Runner-up
- OpenAgora · 8.02/10
Scores higher than the pick on: Capability fit, Developer & agent DX.
- When not to use the pick
- Need zero-cold-start Streamable-HTTP edge hosting for your MCP server and /.well-known endpoints — Cloudflare Workers; public A2A agent card & capability registry — OpenAgora or A2A Registry; hosted MCP directory and inspector — PulseMCP or Glama.
- Lock-in / migration
- The pick has lower stored lock-in risk than runner-up OpenAgora (1 vs 2).
- Sourced price (no comparable unit)
Pick: no sourced price in this job's unit (no_sourced_price).
No cheapest SKU (no_comparable_unit_for_job). No price was invented.
- Free option
