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 mesh.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches across 500+ indexed MCP servers and A2A tools by capability query, returning compressed, firewall-screened results for agent orchestration and tool routing.

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://mesh.agentdiet.dev/v1/execute)
Output
Returns a compressed, token-pruned list of matching MCP servers or A2A tools ranked by relevance to the query, including capability descriptions, endpoint metadata, and Prompt-Guard firewall clearance status. The 85% token compression ensures minimal context overhead for the calling agent.
Example use cases
Swarm tool discovery for coding agents
“Find me all MCP servers in the mesh index that support GitHub dependency auditing or supply-chain security — I need the top results with compressed metadata so my coding agent can pick one.”
Safe endpoint verification before use
“Before my agent calls this endpoint URL https://some-tool.example.com/api, can you check if it's indexed and firewall-cleared in the agent mesh so I know it's safe to proxy through?”
Capability routing for SEC filings
“I need to route my research agent to an MCP tool that can pull SEC filings — search the meta-router index for 'sec filings' and give me the best match with token-efficient output.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability at runtime, especially when token efficiency matters or when you need to verify that an external endpoint is safe before proxying through it. Prefer this over hardcoded tool lists when the agent ecosystem is large, evolving, or unknown.
Side effects
- No matching tools found for the given query — returns empty results or low-confidence matches
- Endpoint URL provided for verification is not indexed — returns unverified or unknown status
- Query too vague or ambiguous — results may include loosely related tools
- Rate limit or payment failure (x402) — agent receives 402 response requiring USDC payment
- Firewall (Prompt-Guard) flags query as potentially injected — request blocked with security warning
