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://email-verify.agentdiet.dev/api/mcp/audit)
Output
Returns a structured list of matching MCP servers and A2A tools from the 500+ indexed catalog, including capability metadata, routing information, and compressed tool descriptions filtered through the Prompt-Guard firewall.
Example use cases
Discover context compression MCP tools
“Search the MCP meta-router for any tools that do context or token compression — I want to find the best-indexed servers for shrinking large prompt contexts before sending them to a model.”
Find GitHub security audit agents
“Look through the indexed MCP servers and A2A tools for anything that can run a GitHub security audit or code vulnerability scan — I need to know what's available and how to connect to it.”
Locate prompt firewall or safety tools
“Search the tool discovery index for any MCP servers or A2A agents that provide prompt injection protection or a prompt-guard firewall — I want to route untrusted input through a safety layer.”

Endpoint
POSThttps://email-verify.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover or route to a specific MCP server or A2A tool without maintaining individual connections to hundreds of services. Ideal for agent orchestration scenarios where the right downstream tool is unknown, or when you want a single safe-proxy entry point with built-in prompt-guard filtering and 85% token compression across the MCP ecosystem.
Side effects
- Empty or too-vague query returns no useful matches
- Query matches too many tools without enough specificity to narrow results
- Endpoint URL verification for an unknown or non-indexed URL returns no match
- Token compression artifacts may reduce fidelity of returned tool descriptions
- Payment required (HTTP 402) if x402 payment header is missing or invalid
