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).
Meta-router that searches 500+ MCP servers and A2A tools by capability query, returning matching endpoints with token-compressed results through a Prompt-Guard firewall

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-broker)
Output
A compressed, token-efficient list of matching MCP servers and A2A tools relevant to the capability query, including endpoint metadata, routed through a Prompt-Guard firewall to filter unsafe or prompt-injected results.
Example use cases
Discovering tools for SEC filing analysis
“Search the MCP broker index for any A2A or MCP tools that can pull and parse SEC filings — I need to find what's available before I wire up my research agent.”
Finding context compression tools for agent swarms
“Can you query the tool broker for MCP servers that support context compression? My agent pipeline is hitting token limits and I need a compressed proxy option.”
Locating email verification tools for a lead pipeline
“Search the A2A tool index for anything that does email verification or B2B contact enrichment — I'm building an outbound lead pipeline and need to know what's indexed and available.”
Technical details
Endpoint
POSThttps://github-audit.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability at runtime, especially when token efficiency matters (85% compression), when safety filtering against prompt injection is required, or when building swarm architectures that need a single connection point to 500+ tools rather than hardcoding individual tool URLs.
Side effects
- No matching tools found for the query — returns empty result set
- Query too vague to match specific capabilities — recommend narrowing search terms
- Firewall blocks a result due to Prompt-Guard detection — flagged tool excluded from response
- Payment required error (HTTP 402) if x402 payment not attached
- Malformed query (empty string) rejected due to minLength:1 constraint
