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://llms-generator.agentdiet.dev/api/mcp/audit)
Output
Returns a structured object listing matching MCP servers and A2A tools relevant to the query, with compressed tool descriptions (up to 85% token reduction) and Prompt-Guard firewall filtering applied. May include tool metadata, endpoint URLs, capability summaries, and routing recommendations.
Example use cases
Discover tools for GitHub security audits
“Search the MCP meta-router for any tools or agents that can do GitHub security audits — I want to see what's available across the 500+ indexed servers.”
Find compressed context tools for agent swarm
“Look up MCP servers that offer context compression capabilities so I can wire them into my agent swarm without blowing my token budget.”
Locate email verification agent endpoint
“Can you search the A2A and MCP tool index for any available email verification services? I need to route my agent to something reliable.”
Technical details
Endpoint
GEThttps://llms-generator.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover and route to MCP servers or A2A tools at runtime rather than hardcoding tool connections. It is especially useful when building multi-agent swarms that need to find the right specialized tool on demand, when token budget is a concern (85% compression), or when safety filtering via Prompt-Guard is required before proxying to third-party agents.
Side effects
- Empty query string returns validation error (query is required, minLength 1)
- No matching tools found for obscure or misspelled capability queries
- Payment required (HTTP 402) if x402 micropayment header not provided
- Upstream MCP server index may be stale or partially unavailable
- Overly broad queries may return too many results with insufficient routing signal
