How this service works
Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-compiler.agentdiet.dev/v1/broker/catalog)
Output
Returns a catalog of matching MCP servers and A2A tools relevant to the search query, with token-compressed metadata including endpoint URLs, capability descriptions, and routing information for swarm or single-agent use.
Example use cases
Discover tools for lead enrichment
“Search the MCP tool catalog for anything that can do B2B lead enrichment or company data lookup — I want to find the best available server for that capability.”
Find on-chain risk analysis agents
“Can you search the broker catalog for MCP servers or A2A tools that handle on-chain risk or crypto wallet analysis?”
Locate GitHub audit tools
“Look through the MCP index and find me any tools that support GitHub security auditing or code repository analysis.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover new tools or MCP servers by capability at runtime, especially when the target tool is not already known. Useful for swarm orchestration, capability routing, and situations where token budget is a concern due to the 85% compression claim.
Side effects
- Query string missing or empty — returns 400 bad request
- No matching tools found for the query — returns empty result set
- Payment not provided or insufficient — HTTP 402 payment required
- Catalog index temporarily unavailable — returns 503
- Query too vague to return meaningful results — broad or unfiltered matches
