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 token-compressed, firewall-screened results to route agent tasks to the right tool.

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/mesh/dispatch)
Output
Returns a token-compressed, Prompt-Guard-screened list of matching MCP servers or A2A tools with metadata about their capabilities, or a validation result if an endpoint URL was submitted as the query. Results are filtered through a prompt-injection firewall before delivery.
Example use cases
Agent swarm tool routing
“I'm building a multi-agent pipeline and need to find which MCP server handles GitHub dependency security audits — can you search the tool index for that capability?”
Endpoint URL safety check
“Before my agent calls this MCP endpoint I found online, can you verify it's indexed and safe to proxy through the mesh router?”
Capability discovery for new agent
“My agent needs to do B2B lead enrichment and tech stack detection — search for any A2A tools in the index that cover those capabilities.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover the right MCP server or A2A tool for a capability at runtime, rather than hardcoding tool endpoints. Ideal for swarm orchestrators, meta-agents, or pipelines that need to self-route across a broad tool ecosystem with built-in safety filtering and token efficiency.
Side effects
- No matching tools found for the given query — returns empty result set
- Endpoint URL provided for verification is not indexed — returns not-found status
- Query string is empty or too vague — returns validation error
- Upstream MCP server unreachable during proxy routing — returns connectivity error
- Payment not fulfilled (x402) — returns 402 Payment Required
