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 llms-generator.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches an index of 500+ MCP servers and A2A tools by capability query, returning compressed, prompt-injection-safe tool descriptions to help agents discover and route to the right external tool or endpoint.

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://llms-generator.agentdiet.dev/v1/workflows/rag-context-sanitizer)
Output
Returns a structured object containing matched tool or server metadata from the 500+ MCP/A2A index, with descriptions compressed by up to 85% using token-efficient encoding and filtered through a Prompt-Guard firewall to remove injection risks. May also return endpoint verification status if a URL is submitted as the query.
Example use cases
Discover tools for GitHub security audits
“Search the tool index for MCP servers or A2A tools that handle GitHub security auditing — I want to find something I can plug into my agent pipeline right away.”
Find an email verification tool
“Look through the tool registry for any capability matching 'email verification' so my agent can route that kind of request to the right MCP server.”
Verify an endpoint URL before use
“Can you check whether this endpoint URL is listed and verified in the A2A and MCP index: https://some-agent-service.example.com/v1/tools/enrich?”
Technical details
Endpoint
GEThttps://llms-generator.agentdiet.dev/v1/workflows/rag-context-sanitizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool supports a given capability at runtime, rather than hardcoding tool references. It is especially useful in multi-agent swarms where tool routing must be resolved dynamically, or when you want to verify whether a known endpoint URL is indexed and compliant. Prefer it over manually browsing MCP registries when you need compressed, safe-to-consume tool metadata for downstream LLM consumption.
Side effects
- Empty or vague query returns no matches or irrelevant results
- Endpoint URL submitted for verification may not be in the index, returning a not-found result
- Service may return HTTP 402 requiring x402 micropayment before responding
- Malformed query (below minLength:1) rejected with validation error
- Index may not reflect newly added or recently updated MCP servers in real time
