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/universal-mcp-gateway)
Output
Returns a filtered, token-compressed list of matching MCP servers or A2A tools relevant to the capability query, along with routing metadata and prompt-injection-screened results from the 500+ indexed endpoints.
Example use cases
Discover tools for SEC filing retrieval
“Search the universal MCP gateway for available tools that can pull SEC filings — I need to find which MCP servers or A2A agents index that capability.”
Route agent to context compression tool
“Use the MCP meta-router to find me a tool for context compression — I want to know which MCP servers support it so my agent can connect through the single-gateway proxy.”
Verify and vet an unknown MCP endpoint URL
“I have this endpoint URL I found online — can you run it through the universal MCP gateway to verify it and check if it's indexed and safe to use?”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools support a given capability without maintaining its own index, or when a safe proxy with token compression and prompt injection protection is needed. Ideal for swarm orchestration where the agent doesn't know ahead of time which tool to call.
Side effects
- Missing or empty query parameter returns validation error
- Query matches no indexed tools, returning empty results
- Upstream MCP server unreachable, resulting in partial results
- Prompt-Guard firewall blocks query flagged as injection attempt
- Payment not processed (x402), resulting in 402 response before results are returned
