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://shopify-spy.agentdiet.dev/v1/universal-mcp-gateway)
Output
Returns a compressed, firewall-filtered list of matching MCP servers and A2A tools relevant to the query, including routing metadata, endpoint URLs, and capability descriptions — with up to 85% token reduction applied to the response payload.
Example use cases
Discovering tools for GitHub security auditing
“Can you search the MCP tool index for any agents or servers that support GitHub security auditing or dependency scanning? I want to know what's available before I build my pipeline.”
Routing to a context compression service
“I need to find an MCP server that specializes in context compression — search the universal gateway index and tell me what endpoints are available and how to connect to them.”
Verifying a specific endpoint before use
“Before I route traffic to https://some-agent.example.com/v1/tool, can you check the universal MCP gateway to verify whether that endpoint is indexed and considered safe to proxy through?”
Technical details
Endpoint
GEThttps://shopify-spy.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 are available for a given capability at runtime, rather than hardcoding specific tool URLs. It is especially useful for swarm orchestration scenarios where the agent must select the best downstream tool from a large indexed pool, or when verifying whether a known endpoint is safe and indexed before proxying traffic through it.
Side effects
- Missing or empty query string returns a validation error
- Query matches no indexed tools, returning an empty result set
- Prompt-Guard firewall blocks queries containing injection-like patterns
- Endpoint URL verification returns unrecognized or untrusted status
- Service unavailability during index refresh windows
