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://github-audit.agentdiet.dev/v1/broker/catalog)
Output
Returns a catalog of matching MCP server and A2A tool entries relevant to the query, including tool names, capability descriptors, endpoint URLs, and routing metadata, filtered through the Prompt-Guard firewall for safety.
Example use cases
Routing agent to right MCP server
“Find me MCP servers in the agentdiet catalog that can do SEC filings retrieval — I want to route my research agent to the most relevant one.”
Discovering compression-capable tools
“Search the tool catalog for any A2A agents that offer context compression or token reduction so I can reduce costs on long-document workflows.”
Verifying endpoint availability
“Can you check the agentdiet broker catalog to see if there's a verified endpoint available for B2B lead enrichment and company tech stack analysis?”
Technical details
Endpoint
POSThttps://github-audit.agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover, search, or route to external MCP servers or A2A tools at runtime without hardcoding individual service URLs. Especially useful in swarm-agent architectures where the right tool for a task is not known in advance, or when token efficiency matters and 85% compression is valuable. Prefer this over direct tool invocation when the tool landscape is broad and you want a safe-proxied, firewall-protected meta-layer.
Side effects
- Empty results if query terms are too narrow or misspelled
- Payment failure if x402 micropayment is not properly initialized
- Query too short (minLength:1 not satisfied) returns validation error
- Firewall blocks query if it resembles prompt injection
- Timeout if catalog index is temporarily unavailable
- Generic object response with no matches if no tools fit the query
