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 compressed, structured listing of matching MCP servers and A2A tools relevant to the capability query, including metadata about each tool, firewall-cleared routing info, and optionally endpoint verification status. Results are token-compressed at ~85% to minimize agent context usage.
Example use cases
Discovering tools for GitHub security audits
“Search the A2A and MCP tool directory for anything that handles GitHub security auditing or code scanning — I need to find what's available before I set up my agent pipeline.”
Verifying a specific MCP endpoint is live
“Can you check whether this endpoint URL is indexed and verified in the MCP registry: https://email-verify.agentdiet.dev/api/mcp/audit — I want to confirm it's actually reachable and trusted.”
Finding context-compression capable agents
“Look up MCP servers that specialize in context compression or token reduction — I'm building a swarm and need to find tools that can shrink my prompts by at least 80%.”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability before routing a task, especially in multi-agent swarm architectures. It is particularly valuable when context window efficiency matters (85% compression) and when prompt injection safety is a concern (Prompt-Guard firewall). Prefer this over static tool registries when you need live, indexed coverage of 500+ servers in a single connection.
Side effects
- Empty query string returns validation error (minLength:1 violated)
- Query too vague returns low-confidence or empty match set
- Endpoint URL verification may fail if target is offline
- Rate limiting or payment failure (x402) blocks response
- Upstream MCP server index may have stale entries for niche capabilities
