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://token-intel.agentdiet.dev/v1/universal-mcp-gateway)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with token-compressed capability descriptions (claiming ~85% compression) and safety-filtered output via a Prompt-Guard firewall. Results include endpoint metadata, tool capabilities, and routing information.
Example use cases
Agent pipeline tool discovery
“I'm building an agent swarm and need to find MCP servers that support GitHub security auditing — can you search the tool index and tell me what's available?”
Capability search for on-chain risk
“Find me any A2A or MCP tools in the index that handle on-chain risk analysis or DEX token intelligence for my trading agent.”
Verifying an endpoint before integration
“Before I add this MCP server to my stack, can you check if this URL is a valid, compliant MCP endpoint? Here's the URL: https://some-mcp-server.example.com”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP or A2A tools exist for a given capability, rather than hard-coding tool integrations. Especially useful for swarm orchestrators, agent pipelines that need runtime tool selection, or developers evaluating MCP server options before integration. Prefer this over manual registry browsing when token budget is a concern, since results are compressed.
Side effects
- Empty or vague query returns low-confidence or no results
- Queried endpoint URL may not be reachable or compliant, returning a validation error
- Index may not reflect real-time availability of all 500+ MCP servers
- Payment required (HTTP 402) if x402 micropayment header is missing or invalid
- Overly broad queries may return too many loosely matched tools
