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/mcp-router)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, including endpoint metadata, capability descriptions, and routing information, filtered through a Prompt-Guard firewall with 85% token compression applied to responses.
Example use cases
Discover tools for SEC filings analysis
“Can you search the MCP router index for any tools or agents that handle SEC EDGAR filings or financial document analysis? I want to route my agent to the right endpoint.”
Find context compression MCP servers
“Search for MCP servers that offer context compression or token reduction — I need to cut down the tokens my agent pipeline is using and want to see what's available in the router index.”
Locate prompt firewall or AI safety tools
“Look up what tools are indexed in the MCP router for prompt injection protection or prompt firewall capabilities — I'm building a swarm and need to guard against malicious inputs.”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/mcp-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-connection gateway to discover and route across a large corpus of 500+ MCP servers and A2A tools without maintaining separate integrations. Ideal for agent swarms that need dynamic tool discovery, especially when token efficiency and prompt safety are priorities. Prefer over manual tool registries or direct MCP connections when you want centralized discovery with built-in firewall protection.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability queries
- Prompt-Guard firewall may block certain query patterns flagged as suspicious
- Rate limiting or payment failures at $0.01/call via x402
- Malformed endpoint URL when used in URL-verification mode returns error
- Index may not reflect newly added MCP servers immediately
