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://polymarket-odds.agentdiet.dev/api/mcp/audit)
Output
Returns a list of matching MCP server or A2A tool entries relevant to the capability query, with compressed metadata (85% token reduction) describing each tool's capabilities, endpoint details, and safety status as filtered by the Prompt-Guard firewall.
Example use cases
Agent tool discovery for SEC filings
“Search the MCP tool index for anything that handles SEC filings or public financial disclosures — I'm building a research agent and need to know which servers support that capability.”
Finding GitHub security audit tools
“Can you search for MCP servers or A2A tools that do GitHub security audits or code vulnerability scanning? I want to wire one into my CI pipeline agent.”
Routing swarm to right capability
“I'm setting up a multi-agent swarm and need to find which indexed MCP server handles domain OSINT or email verification — search the registry and give me the best match.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to discover which MCP servers or A2A tools support a particular capability without manually cataloguing hundreds of servers. It is especially useful when building swarms or multi-agent pipelines that need dynamic tool routing, or when you want compressed tool metadata with built-in prompt-injection filtering rather than raw tool directories.
Side effects
- Missing or empty 'query' parameter returns a 400 validation error
- Query too broad returns too many low-relevance results
- No matching tools found returns empty result set
- Upstream MCP index unavailable causes 502 or timeout
- Payment not included or failed results in HTTP 402 response
