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/api/mcp/audit)
Output
Returns a structured object listing matched MCP servers or A2A tools relevant to the query, including compressed capability descriptors, safety/firewall status, and routing metadata — with up to 85% token reduction compared to raw tool manifests.
Example use cases
Agent swarm tool discovery
“Search across all indexed MCP servers for tools that do 'context compression' — I need to find which ones are available so my agent swarm can pick the best one.”
Verifying a specific MCP endpoint
“Can you look up this MCP endpoint URL in the tool index and tell me if it's verified and what capabilities it exposes: https://example-mcp-server.dev/api”
Finding SEC filing tools for research agent
“I'm building a research agent — can you search the MCP tool registry for anything related to 'SEC filings' or financial document retrieval?”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability, rather than hardcoding tool URLs. Ideal for multi-agent swarms, meta-orchestrators, or agents that need to self-configure their tool belt at runtime. Prefer this over a static tool registry when you need real-time index freshness, token-compressed manifests, or built-in prompt-injection firewall filtering on returned tool descriptions.
Side effects
- Missing or empty 'query' parameter returns a validation error
- Query matches no indexed tools — returns empty results set
- Endpoint URL verification fails if the target is unreachable or unregistered
- Rate limiting or payment failure (HTTP 402) if x402 credits are exhausted
