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/execute)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with compressed capability descriptions (85% token reduction), along with routing information and any prompt firewall screening results.
Example use cases
Discover SEC filing agent tools
“Search the MCP tool router for any agents or servers that can pull SEC filings or financial disclosures — I need to find the right tool for a research task.”
Find GitHub security audit capability
“I need an agent that can do GitHub security audits — can you search the MCP index to find which tools support that and route me to the best one?”
Route B2B lead enrichment query
“Look up what tools are available in the agent network for B2B lead enrichment or company data — I want to find a capable MCP server I can route lead data through.”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover which MCP server or A2A agent tool supports a specific capability across a large index (500+), especially when you want token-efficient results and built-in prompt injection protection — as opposed to querying individual tool registries or maintaining your own tool index.
Side effects
- Empty or too-vague query returns no relevant matches
- Queried endpoint URL is unreachable or non-compliant, returning an error
- No indexed tools match the requested capability
- Rate limiting or payment failure at $0.01 per call via x402
- Prompt-Guard firewall blocks a query flagged as unsafe
