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 github-audit.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-11-02).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, 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://github-audit.agentdiet.dev/v1/x402-gateway)
Output
A JSON object listing matching MCP servers and A2A tools relevant to the query, with compressed descriptions, endpoint URLs, capability tags, and firewall-cleared routing metadata — approximately 85% token-reduced compared to raw tool manifests.
Example use cases
Agent discovers context compression tools
“I need to find MCP servers that can compress context or summarize long documents — search your tool index for anything related to 'context compression' or 'token reduction'.”
Routing agent to GitHub security tools
“Look up what A2A or MCP tools are available for GitHub security auditing — I want to know which endpoints I can route my agent to for scanning repos.”
Finding DeFi data endpoints for swarm
“Search the MCP tool index for anything related to DeFi yield or stablecoin liquidity pools — I'm building a swarm and need to wire up the right tools.”
Technical details
Endpoint
POSThttps://github-audit.agentdiet.dev/v1/x402-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding tool URLs. Ideal for swarm architectures where the routing layer needs real-time tool lookup with safe proxying and token budget constraints.
Side effects
- Query too vague returns zero or low-relevance matches
- Prompt-Guard firewall may block queries resembling injection attempts
- No MCP server in the index covers the requested capability
- Payment not processed (x402 response) if USDC authorization fails
- Malformed query string returns validation error
