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://mesh.agentdiet.dev/v1/universal-mcp-gateway)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, including endpoint metadata, compressed descriptions, and safety/firewall status — with up to 85% token reduction compared to raw discovery.
Example use cases
Discover tools for context compression
“I need to find MCP servers or A2A tools that specialize in context compression — can you search the universal gateway and tell me what's available?”
Route agent to GitHub security auditor
“Look up 'github security audit' in the MCP tool discovery gateway and find me the best endpoint I can point my coding agent at.”
Verify a specific endpoint is safe
“Can you check whether this endpoint URL is indexed and safe in the universal MCP gateway: https://some-mcp-server.example.com/v1/tool?”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to delegate a task to, especially when the agent doesn't know the exact backend endpoint in advance. It is particularly valuable when operating across a large heterogeneous tool ecosystem (500+), when token budget is tight (85% compression), or when untrusted tool responses need firewall protection.
Side effects
- Query string too short or empty — returns validation error
- No matching tools found for the capability query — returns empty result set
- Endpoint URL not indexed or unrecognized — returns no match
- Service temporarily unavailable — returns 5xx error
- Payment not completed (x402) — request blocked before processing
