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-router)
Output
Returns a token-compressed list of matched MCP servers or A2A tools relevant to the capability query, including endpoint URLs, descriptions, and routing metadata, with prompt-injection filtering applied via the built-in Prompt-Guard firewall.
Example use cases
Discover tools for SEC filings
“Search the MCP tool index for any servers that can retrieve SEC EDGAR filings or 10-K financial data — I want to find the best available tool for that.”
Find context compression endpoints
“Look through the MCP meta-router for endpoints that support context compression or token reduction — which ones are available and what do they do?”
Route agent to company enrichment tool
“I need my agent to enrich a list of B2B companies with tech stack and contact data — can you search the A2A tool index and find which MCP server handles company enrichment best?”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover the right tool or MCP server for a capability it does not already know, especially when routing across a large ecosystem of 500+ servers. Ideal for swarm agent architectures where tool selection must be resolved at runtime. Prefer this over hardcoded tool lists when the required capability is unknown in advance or when token-efficient tool discovery is a priority.
Side effects
- Empty or vague query returns no meaningful matches
- Query too broad returns too many low-relevance results
- Endpoint URL verification may fail if target is offline
- Rate limiting or payment failure (HTTP 402) if USDC balance is insufficient
- Index may not reflect recently added MCP servers if not yet crawled
