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://onchain-risk.agentdiet.dev/v1/workflows/b2b-lead-enrichment)
Output
Returns a JSON object containing matching MCP servers or A2A tools relevant to the capability query, with compressed tool descriptions (up to 85% token reduction) and safety-filtered metadata to help agents select and route to appropriate downstream capabilities.
Example use cases
Find lead enrichment tools for sales pipeline
“Search the tool index for anything that can enrich B2B leads with company firmographics, employee count, or industry info — I want to plug it into my sales pipeline automation.”
Discover MCP servers for domain OSINT
“Can you look through the MCP tool registry and find me servers or agents that specialize in domain OSINT or company intelligence gathering?”
Locate email verification agents in ecosystem
“Search for A2A tools or MCP servers that can verify business email addresses — I need something I can route verification requests through for a lead qualification workflow.”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/workflows/b2b-lead-enrichment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP servers or A2A tools can handle a specific capability without connecting to hundreds of individual servers — especially useful for B2B lead enrichment, company intelligence, or data enrichment workflows where the right downstream tool is unknown. Prefer this over direct MCP connections when token budget is constrained (85% compression) or when prompt safety is a concern.
Side effects
- Empty query string returns validation error (minLength:1 not met)
- No matching tools found for obscure or misspelled capability query
- Upstream MCP server unavailability may result in partial or stale index results
- HTTP 402 payment required if x402 payment header is missing or insufficient
- Prompt injection attempts blocked by Prompt-Guard firewall, returning filtered or rejected response
