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/v1/workflows/rag-context-sanitizer)
Output
Returns a list of matching MCP servers and A2A tools relevant to the capability query, with compressed metadata (up to 85% token reduction) and Prompt-Guard firewall filtering applied. Includes tool names, descriptions, endpoint URLs, and routing information.
Example use cases
Routing SEC filing tasks in agent swarm
“Find me all the MCP servers or A2A tools in the index that can handle SEC filings or financial document retrieval — I need to route my agent's next task to the right one.”
Discovering email verification capabilities
“Search the tool discovery index for anything that does email verification or domain OSINT — I want to see which agents or MCP servers support that.”
Finding context compression tools
“What MCP endpoints in the swarm support context compression? I need to cut down my token usage and want to find the right tool for that.”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/workflows/rag-context-sanitizer?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool in a large ecosystem can fulfill a specific capability, rather than hardcoding tool endpoints. Especially useful when building meta-agents or swarm orchestrators that need to route subtasks to the most appropriate specialist tool at runtime.
Side effects
- Empty or too-generic query returns no useful matches
- Query for an unsupported capability returns empty result set
- Endpoint URL verification fails if the target is offline
- Rate limiting or 402 payment required if quota exceeded
- Malformed query string causes validation error
