Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from polymarket-odds.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-28).
Routes a natural-language capability query across 500+ indexed MCP servers and A2A tools, returning matching endpoints with token-compressed results and prompt-injection firewall protection.

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/v1/mesh/dispatch)
Output
A JSON object listing the best-matching MCP servers and A2A tools for the query, with token-compressed metadata about each endpoint, capability descriptions, and routing information — filtered through a Prompt-Guard firewall to block injected payloads.
Example use cases
Finding a context compression tool
“Search your MCP mesh for any tool that does context compression or token reduction — I need to reduce what I send to my LLM and want to know what's available.”
Routing to a GitHub security auditor
“Find me an MCP server or A2A tool in the mesh that can audit GitHub repositories for security vulnerabilities — I need to point my agent pipeline at the right one.”
Discovering B2B lead enrichment agents
“What tools do you have indexed for B2B lead enrichment or company data enrichment? Search the 500+ servers and show me the best matches.”
Technical details
Endpoint
POSThttps://polymarket-odds.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which MCP server or A2A tool is best suited for a task at runtime, rather than hardcoding tool URLs. Especially useful for swarm architectures, meta-agents, or pipelines that need to route sub-tasks to specialized tools without prior knowledge of the full tool registry. Prefer this over manual tool registries when the capability space is large or frequently changing.
Side effects
- No matching tools found for an obscure or niche query — returns empty results
- Query too short or vague — minLength:1 enforced but semantically empty strings may return low-quality matches
- Prompt-Guard firewall blocks queries that resemble injection attempts — may reject legitimate but oddly phrased inputs
- External MCP servers temporarily offline — routing succeeds but proxied call fails
- Payment required error (HTTP 402) if x402 payment header is missing or insufficient
