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://hn-pulse.agentdiet.dev/v1/mcp-router)
Output
Returns a compressed list of matching MCP servers or A2A tools from a 500+ item index, including tool metadata, capability descriptions, and safety-filtered results from the Prompt-Guard firewall, all with claimed 85% token compression relative to raw tool manifests.
Example use cases
Discover SEC filing tools for agents
“Search for MCP servers or A2A tools that can pull SEC filings and financial disclosures — I want to find the best available option across your full index.”
Find on-chain risk analysis capabilities
“Can you query the MCP router for anything that does on-chain risk scoring or blockchain transaction analysis? I need to know what's indexed and available.”
Verify a specific MCP endpoint
“Check if this endpoint URL is in your index and tell me whether it's compliant: https://some-mcp-server.example.com/v1/tools — I want to confirm it's safe to use.”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/mcp-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP servers or A2A tools exist for a given capability without connecting to hundreds of individual servers — especially useful when you want a single-connection lookup with built-in safety filtering and token-compressed results for AI agents operating under context limits.
Side effects
- Empty or too-vague query returns no meaningful matches
- Query string missing — required field causes 400 error
- No tools match a very niche or misspelled capability query
- Prompt-Guard firewall may filter or block queries it flags as unsafe
- x402 payment failure if USDC balance is insufficient (HTTP 402)
- Downstream MCP servers may be offline even if indexed
