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 2026-10-21).
Searches an index of 500+ MCP servers and A2A tools by capability keyword or URL, returning matching endpoints with token-compressed metadata 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/tool-search)
Output
Returns a list of matching MCP servers or A2A tools relevant to the search query, including compressed metadata about each tool's capabilities, endpoint URLs, and relevant schema information — filtered through a Prompt-Guard firewall to prevent injection attacks.
Example use cases
Discover tools for GitHub security auditing
“Search the MCP tool index for anything related to GitHub security, code auditing, or repository analysis — I need to pick the best available tool for scanning a public repo.”
Find context compression capable agents
“What MCP servers or A2A tools in your index can do context compression or token reduction? I'm trying to cut down on token usage in my agent pipeline.”
Route to domain OSINT capability
“I need a tool for domain OSINT and DNS reconnaissance — can you search your tool index and tell me what's available so I can route my agent to the right one?”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool is best suited for a specific capability — especially useful for swarm architectures or orchestration layers that need to route sub-tasks to specialized tools without pre-wiring every connection. Prefer it over hardcoded tool registries when the tooling landscape is large (500+), changes frequently, or when prompt-injection safety is a concern.
Side effects
- Empty query string returns validation error (minLength:1 not met)
- Query too vague returns zero results or low-relevance matches
- Queried URL does not match any indexed endpoint
- Service unavailable if meta-router backend is down
- x402 payment failure if USDC balance insufficient for $0.01 fee
