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://x402-audit.agentdiet.dev/v1/broker/execute)
Output
Returns a list of matching MCP servers or A2A tool endpoints relevant to the capability query, including metadata about each tool. Results are token-compressed (up to 85% reduction) and have passed through the Prompt-Guard firewall before being returned.
Example use cases
Discover tools for GitHub security auditing
“Search the tool index for any MCP servers or A2A agents that can do GitHub security audits — I want to know what's available before I route my pipeline.”
Find context compression capability
“I need an MCP tool that does context compression — can you search the meta-router and tell me which servers support that?”
Route to domain OSINT tool
“Find me a safe-proxied A2A or MCP endpoint that handles domain OSINT and tell me how to connect to it.”
Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to discover or route to one of many MCP or A2A tools without maintaining individual connections to each. Prefer it when you want a single normalized interface across 500+ tools, when token budget is tight (85% compression), or when you need prompt-injection protection before forwarding queries to external agents.
Side effects
- No matching tools found for the given query — returns empty result set
- Query string is empty or too short — rejected by schema validation (minLength:1)
- Upstream MCP server is offline — routing may fail or return degraded results
- Prompt injection attempt detected by Prompt-Guard firewall — request blocked
- Payment not processed (x402) — endpoint returns 402 before serving results
