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/broker/execute)
Output
A structured object listing matching MCP servers or A2A tool endpoints relevant to the capability query, with token-compressed metadata and results filtered through a Prompt-Guard firewall to prevent prompt injection from malicious tool responses.
Example use cases
Discover tools for GitHub security audits
“Search the A2A and MCP tool index for anything that can scan GitHub repos for security vulnerabilities or exposed secrets — I want to route my agent to the right server automatically.”
Find context compression MCP servers
“I'm hitting token limits in my agent pipeline — can you search the MCP index for any servers that support context compression or token budget optimization?”
Route to on-chain risk analysis tools
“Search for A2A or MCP tools that handle on-chain risk or DEX token intelligence so I can plug the right one into my crypto monitoring workflow.”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to discover which MCP servers or A2A tools exist for a given capability without manually connecting to hundreds of individual servers. It is especially valuable when building dynamic agent pipelines that need to route tasks to the right tool at runtime, when you want token-compressed metadata to avoid bloating context windows, or when you need prompt-injection protection (Prompt-Guard firewall) before routing to untrusted external tool endpoints.
Side effects
- Empty or vague query returns no matches or irrelevant results
- Query for a niche capability not indexed returns empty result set
- Upstream MCP server index unavailable causes lookup failure
- Malformed query string triggers validation error
- Rate limiting or payment failure (402) blocks the request
