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://defi-yield.agentdiet.dev/v1/workflows/b2b-lead-enrichment)
Output
Returns a compressed, Prompt-Guard-filtered list of matching MCP servers and A2A tools from a 500+ entry index, including endpoint metadata, capability descriptions, and routing information relevant to the search query or verified URL.
Example use cases
Discovering context compression tools
“Search the agent tool index for anything that does context compression or token reduction — I want to find an MCP server my agent can use to cut down prompt length before calling expensive models.”
Finding SEC filings capability for research agent
“I'm building a research agent and need to know which MCP or A2A tools in the index can pull SEC filings — can you search for 'SEC filings' and show me what's available?”
Verifying a specific MCP endpoint URL
“Can you check whether this endpoint URL is listed and compliant in the tool registry: https://defi-yield.agentdiet.dev/v1/workflows/b2b-lead-enrichment — I want to confirm it's indexed and safe to route to.”
Technical details
Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/workflows/b2b-lead-enrichment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool can handle a specific capability at runtime, especially when the agent ecosystem is large and you want a single connection point with built-in token compression and prompt security filtering rather than hardcoding individual tool URLs.
Side effects
- Empty query string returns validation error (minLength:1 not met)
- Query too vague returns low-relevance or no matches
- Endpoint URL verification returns not-found if URL is not indexed
- Upstream MCP index unavailability causes 5xx response
- Payment not processed (x402) blocks access entirely
