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 structured list of matching MCP servers or A2A tools relevant to the query, including endpoint URLs, capability descriptions, and routing metadata — delivered with 85% token compression and filtered through a Prompt-Guard firewall.
Example use cases
Find tools for GitHub security audits
“Search the MCP tool index for anything that can run GitHub security audits or repository code scanning — I want to see what's available and how to call it.”
Discover B2B lead enrichment agents
“Can you look up what A2A tools are available for B2B lead enrichment and company data enrichment? I want to route my leads through the best available agent.”
Locate context compression MCP servers
“Search the meta-router for MCP servers that support context compression — I'm trying to reduce token usage in my agent pipeline and need to find what's indexed.”
Technical details
Endpoint
POSThttps://email-verify.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to any of 500+ MCP servers or A2A tools from a single connection, especially when token efficiency matters or when you need a safety firewall layer between your agent and external tools. Prefer this over direct MCP connections when the target tool is unknown and needs to be discovered first.
Side effects
- Empty query string returns validation error
- No matching tools found for an obscure capability query returns empty result set
- Firewall (Prompt-Guard) blocks queries containing prompt injection patterns
- Upstream MCP server unavailable causes partial results
- Malformed endpoint URL in query returns verification error
