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/workflows/rag-context-sanitizer)
Output
Returns a filtered list of matching MCP servers and A2A tools from the 500+ indexed registry, with token-compressed metadata, relevance rankings, prompt-safety status, and routing recommendations for the queried capability or verified endpoint URL.
Example use cases
Discovering SEC filings tools for agent
“Search your indexed MCP servers and A2A tools for anything that can pull SEC filings or EDGAR data — I need to find the right tool for my research agent.”
Routing agent queries to email verification
“Find me an MCP endpoint or A2A tool in the index that handles email verification — something with a prompt firewall so it's safe to call from my agent pipeline.”
Locating context compression capability
“Which of the 500-plus indexed tools can do RAG context sanitization or token compression? Search the tool index for that capability.”

Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/workflows/rag-context-sanitizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool can fulfill a capability at runtime, rather than hard-coding tool endpoints. Especially useful when building swarm-style multi-agent systems that need safe, token-efficient tool routing across a large heterogeneous index, or when you need prompt-injection firewall protection on inbound tool context.
Side effects
- Empty or too-short query returns no results
- Query matches no indexed tools — empty result set
- Endpoint URL verification returns unresolvable or non-compliant target
- Payment not processed — HTTP 402 returned blocking access
- Index may be stale if a tool was recently added or removed
- Overly broad queries may return too many loosely matched tools
