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/x402-gateway)
Output
Returns a ranked list of matching MCP servers and A2A tools for the query, with compressed response payloads (up to 85% token reduction), safety-filtered through a Prompt-Guard firewall, and routing metadata pointing to the appropriate tool endpoint.
Example use cases
Find tools for GitHub security audits
“Can you search the MCP tool index for any servers that handle GitHub repository security audits or dependency scanning? I want to route my agent through a single connection.”
Discover context compression tools
“Search for MCP tools or A2A agents that specialize in context compression — I need to reduce token usage in my agent pipeline.”
Route to domain OSINT capability
“I need to find an MCP server or A2A tool that does domain OSINT and WHOIS lookup — can you query the tool discovery index and route me to the right one?”
Technical details
Endpoint
POSThttps://hn-pulse.agentdiet.dev/v1/x402-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool. Ideal for multi-tool orchestration scenarios where the capability landscape changes, or when token budget is constrained and 85% compression is valuable. Also useful as a safe proxy that filters prompt-injection from upstream tool responses.
Side effects
- No matching tools found for the query — returns empty results
- Query too vague or malformed — minLength:1 validation error
- Prompt-Guard firewall blocks a potentially malicious query
- Downstream MCP server unavailable — routing failure
- Payment not processed — HTTP 402 returned before results
