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/a2a-mesh)
Output
Returns a JSON object containing matching MCP servers and A2A tool endpoints relevant to the capability query, with compressed metadata and Prompt-Guard firewall screening applied. May include endpoint URLs, capability descriptions, compliance status, and routing information.
Example use cases
Finding a context compression tool
“Can you search the MCP tool index for any servers that support context compression or token reduction? I want to find an agent-compatible endpoint I can route through.”
Discovering GitHub security audit tools
“Look up what A2A or MCP tools are available for GitHub security auditing — I need to find something that can scan repos for vulnerabilities.”
Verifying an agent endpoint URL
“Can you check whether this URL is a valid, compliant A2A endpoint: https://someagent.example.com/v1/agent — I want to know if it passes the mesh's compliance checks before I connect to it.”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/a2a-mesh?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, rather than hardcoding specific tool URLs. It is especially useful when building swarms or orchestrators that need to route tasks to the best available tool, or when verifying whether a remote agent endpoint is compliant before connecting to it.
Side effects
- Missing or empty 'query' parameter returns a 400 validation error
- No matching tools found for a niche or misspelled capability query returns empty results
- Payment required (HTTP 402) if x402 micropayment header is not included
- Upstream MCP server index temporarily unavailable causes degraded or partial results
- Queried endpoint URL fails compliance check and returns audit failure details
