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/a2a-mesh)
Output
Returns a structured list of matching MCP servers or A2A tool endpoints relevant to the capability query, with compressed metadata (85% token reduction) describing each tool's function, endpoint URL, and routing instructions.
Example use cases
Discover tools for B2B lead enrichment
“I need to find an MCP tool that can enrich B2B leads with company data — search the tool index for 'company enrichment' and tell me what's available.”
Route agent query through prompt firewall
“Can you search the A2A mesh for a safe-proxy route that handles 'prompt injection firewall' so my agent swarm can filter untrusted inputs before processing?”
Find GitHub security audit capability
“Look up what MCP servers are available for 'github security' audits — I want to know which indexed tools I can use to scan repos for vulnerabilities.”
Technical details
Endpoint
POSThttps://email-verify.agentdiet.dev/v1/a2a-mesh?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool handles a specific capability, rather than hardcoding tool endpoints. Ideal for multi-agent swarms that need to route tasks to the right specialized tool at runtime with minimal token overhead.
Side effects
- Empty or vague query returns no meaningful matches
- Query too broad returns too many low-relevance results
- Endpoint URL verification fails if the target is offline
- Prompt-Guard firewall may block queries flagged as injection attempts
- Payment failure via x402 prevents execution
