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 agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches and routes across 500+ MCP servers and A2A tools via a single compressed meta-router endpoint with 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://agentdiet.dev/v1/bundle-execute)
Output
Returns a compressed index of matching MCP servers and A2A tool endpoints relevant to the query, including capability metadata, with up to 85% token reduction compared to raw tool manifests. May include safety flags from the Prompt-Guard firewall if a queried endpoint is flagged.
Example use cases
Routing agent to right MCP tool
“My agent needs to do GitHub security audits — search across all the indexed MCP servers and A2A tools to find which ones support that, and give me the compressed metadata so I can wire it up.”
Discovering email verification tools
“Can you look up which MCP servers or A2A tools in the index handle email verification? I want to find the best option before I build my lead enrichment workflow.”
Validating an endpoint before use
“I have this endpoint URL I want to use in my agent swarm — can you run it through the tool discovery router to verify it's a legitimate, indexed capability and check if there are safer alternatives?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/bundle-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP servers or A2A tools support a given capability without manually querying each one — especially useful for agent orchestration layers that need to route tasks dynamically, compress tool manifests to save tokens, or verify an endpoint's legitimacy before proxying through it. Prefer this over manual MCP server catalogs when building multi-agent swarms that need real-time tool routing.
Side effects
- Empty or vague query returns low-relevance results
- Queried endpoint URL not found in the 500+ server index
- Prompt-Guard firewall may block or sanitize queries containing injection patterns
- Payment required error (HTTP 402) if x402 micropayment not provided
- Timeout if upstream MCP server index is unavailable
- Overly broad queries may return too many results to be useful
