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 2026-10-23).
Searches an index of 500+ MCP servers and A2A tools by capability query, returning matching endpoints with token-compressed results via a Prompt-Guard firewall proxy

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 capability query, with compressed metadata (85% token reduction), endpoint URLs, descriptions, and routing information, filtered through a Prompt-Guard firewall to block adversarial content.
Example use cases
Discovering context compression tools
“I want to find MCP tools or A2A agents that handle context compression — search for anything related to token reduction or summarization so I can wire one into my pipeline.”
Finding SEC filings capability
“Search the MCP tool index for anything that can pull SEC filings or EDGAR data — I need to route my agent to a tool that can fetch financial disclosures for a public company.”
Routing swarm agents to right tool
“My agent swarm needs to find a tool for B2B lead enrichment — search across all indexed MCP servers for something that extracts emails and tech stack signals from a company domain.”
Technical details
Endpoint
POSThttps://github-audit.agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hard-coding a specific API. Ideal for swarm architectures where agents must self-route to the right tool at runtime, or when building meta-agents that orchestrate other agents across a large tool ecosystem. Prefer this over manual tool registries when the tool landscape changes frequently or when token efficiency in discovery is important.
Side effects
- Empty or too-short query returns no results or validation error
- Query too broad returns low-relevance tool matches
- Payment failure (x402) if USDC balance insufficient — returns 402 status
- Firewall blocks query if flagged as adversarial by Prompt-Guard
- Timeout if meta-index is unavailable or overloaded
- Invalid idempotency key format returns 400 error
