x402
IMPERIUM A2A MESH — MCP Gateway Discovery & Tool Search is a paid API for AI agents from mesh.agentdiet.dev, paid per call via x402 or MPP, $0.01/call, status unknown (last checked 2026-10-22).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning matching endpoints with token-compressed results via a single connection

How this service works
Autonomous 28-node A2A Swarm Mesh coordinator supporting live A2A JSON-RPC handshakes, KYA on-chain trust scoring, MCP-to-A2A schema bridging, and multi-agent council fan-out.
Output
Returns a paginated list of matching MCP server or A2A tool entries from the 500+ endpoint index, including endpoint metadata, capability descriptions, and potentially token-compressed summaries. Response schema is a generic object; actual fields include matched tools and a next-page cursor.
Example use cases
Discover tools for financial data
“Search the agent mesh for MCP endpoints that handle SEC filings or public company financial data — show me up to 30 results.”
Find capability for lead enrichment
“I need to find A2A tools that can do B2B company enrichment or contact discovery — search the mesh index for anything matching 'company enrichment' and return the top 10.”
Locate a prompt injection firewall tool
“Can you search the MCP gateway for tools related to prompt injection detection or jailbreak filtering? I want to see what's indexed under that capability.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/mcp-gateway?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hardcoding tool endpoints. Ideal for swarm orchestration, meta-agent routing, and building agent pipelines that need to find the right tool at runtime. Prefer this over maintaining a static tool list when the tool landscape changes frequently or when you need 85% token-compressed discovery in a single connection.
Side effects
- Empty query string returns validation error (minLength:1 required)
- Query returns zero results if no indexed tools match the capability
- Pagination cursor mismatch or expiry causes fetch failure
- x402 payment not processed results in 402 response and no data
- Gateway may return partial results if upstream MCP servers are unreachable
