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 matched set of MCP servers or A2A tools from the 500+ indexed catalog that match the capability query, with token-compressed responses (up to 85% compression) and metadata about each matching endpoint, filtered through a Prompt-Guard firewall for safety.
Example use cases
Discovering SEC filing tools for an agent
“Search the MCP router index for any tools or servers that handle SEC filings or EDGAR data — I need to find what's available before wiring it into my research agent.”
Finding prompt firewall capabilities
“Can you query the MCP meta-router for 'prompt firewall' or 'prompt injection guard' tools? I want to know which indexed servers offer that protection before routing my swarm through them.”
Locating GitHub security audit tools
“Search the universal tool index for MCP servers or A2A agents that can do GitHub security audits — I need something I can plug into my CI pipeline agent.”

Endpoint
POSThttps://email-verify.agentdiet.dev/v1/mcp-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to dynamically discover which MCP servers or A2A tools are available for a given capability without maintaining your own index. It is especially useful when building agent swarms that need a single routing layer across hundreds of tools, when token budget is a concern (85% compression), or when you want prompt injection protection baked into tool discovery.
Side effects
- Empty or vague query string returns no useful matches
- Query for a capability not yet indexed returns empty results
- Prompt-Guard firewall may block queries flagged as adversarial
- Network timeout if upstream MCP servers are unreachable
- Payment required (HTTP 402) if x402 micropayment not included
