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://agentdiet.dev/v1/universal-mcp-gateway)
Output
Returns a structured object listing matching MCP servers and A2A tools for the query, including tool metadata, routing information, safety status from the Prompt-Guard firewall, and token-compressed capability descriptions to minimize context usage.
Example use cases
Routing agent to right MCP tool
“I need to find an MCP server that can do context compression for my long-context agent pipeline — search across your indexed tools and tell me what's available.”
Verifying a third-party endpoint before calling it
“Before I connect my agent to this endpoint at https://some-mcp-tool.example.com, can you check it through the universal gateway to verify it's legitimate and not injecting anything malicious?”
Discovering tools for company enrichment
“My agent needs to enrich B2B leads with company data — search the MCP tool index for anything that does company enrichment or lead intelligence and give me the best options.”

Endpoint
GEThttps://agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single connection to discover, compare, or safely route to any of 500+ MCP or A2A tools without manually cataloging individual endpoints. Especially useful when you want built-in prompt-injection protection on tool responses and 85% token compression to minimize LLM context costs.
Side effects
- Empty or too-vague query returns no matches
- Unrecognized endpoint URL fails verification check
- Query times out if indexing is delayed or stale
- Payment not processed (x402 402 response) if micropayment fails
- Response schema is unspecified — output structure may vary per query type
