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://workflows.agentdiet.dev/v1/workflows/b2b-lead-enrichment)
Output
Returns a compressed, Prompt-Guard-filtered list of matching MCP servers or A2A tools relevant to the search query, including metadata about each tool's capabilities, or verification status if an endpoint URL is provided. Results include up to 85% token compression for efficiency.
Example use cases
Discover lead enrichment agent tools
“Search the MCP tool index for anything that can help with B2B lead enrichment — I'm building a sales prospecting agent and need to find tools that pull company data and contact info.”
Find SEC filing analysis tools
“Look through the A2A and MCP server index for tools that handle SEC filings — I need an agent capability that can pull and analyze company financial disclosures.”
Verify a specific MCP endpoint exists
“Can you check whether the endpoint at https://workflows.agentdiet.dev/v1/workflows/b2b-lead-enrichment is listed and compliant in the MCP tool index?”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/workflows/b2b-lead-enrichment?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools support a given capability, especially when building multi-agent pipelines that require routing to the right specialized tool. Prefer this over manually curated tool lists when you need access to a broad index (500+) of live agent capabilities with built-in safety filtering.
Side effects
- Empty query string returns validation error
- No matching tools found for niche capability query returns empty results
- Endpoint URL verification may fail if target is offline or non-compliant
- Rate limiting or payment failure (HTTP 402) if x402 payment not satisfied
- Overly broad queries may return low-relevance results
