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://json-repair.agentdiet.dev/v1/mesh/dispatch)
Output
Returns a structured JSON object listing matching MCP servers or A2A tools ranked by relevance to the query, with token-compressed metadata, capability summaries, and safe-proxy routing details. When given a URL, returns compliance and verification status for that endpoint.
Example use cases
Discover tools for SEC filings
“I need to find an MCP server or A2A agent that can pull SEC filings — search the tool index for 'sec filings' and tell me what's available.”
Route agent to GitHub audit tool
“Find me the best available MCP tool for GitHub security auditing — search for 'github security' in the tool directory and return the matching endpoints.”
Verify an endpoint before calling it
“Before I send traffic to https://some-mcp-server.example.com/tools, can you run it through the mesh dispatch to verify it's a legitimate, compliant MCP endpoint?”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability at runtime, rather than hard-coding a specific API. Especially useful when building swarm architectures that need to self-assemble tool chains, or when you want a single firewall-protected gateway to vet external MCP endpoints before connecting to them.
Side effects
- Missing or empty query parameter returns 400 error
- No matching tools found for obscure or misspelled capability queries
- Endpoint URL verification may fail for servers that are offline or non-compliant
- Payment required (HTTP 402) if x402 credentials are not supplied
- Rate limiting may apply under high query volume
