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://serp-extract.agentdiet.dev/v1/mesh)
Output
Returns a compressed, token-pruned list of matched MCP servers and A2A tools relevant to the capability query, including metadata about each tool, routing info, and Prompt-Guard firewall status — all delivered through a single connection.
Example use cases
Discover tools for a swarm agent
“Search the tool mesh for any MCP servers or A2A agents that can do context compression or token reduction — I'm building a swarm and need to find the right capability quickly.”
Route a GitHub security audit request
“Find me an MCP tool in the mesh that handles GitHub security audits or open-source vulnerability scanning so my agent can call it through the safe-proxy without direct integration.”
Verify an endpoint URL in the mesh
“Check if the endpoint https://some-tool.example.com/api is registered and reachable in the A2A tool mesh, and tell me what capability it covers.”
Technical details
Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover and route to one of 500+ MCP or A2A tools without managing individual server connections, especially when token efficiency and prompt security (firewall) are priorities. Prefer over direct tool integration when the target capability is unknown or when building multi-agent swarms that need dynamic tool resolution.
Side effects
- Empty or vague query returns no results or irrelevant matches
- Queried endpoint URL not found in the mesh index
- Mesh index temporarily unavailable (500 error)
- x402 payment not included or rejected, returning 402 response
- Query too short (minLength:1 violated) returns validation error
- Rate limiting if too many queries in rapid succession
