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/bundle-execute)
Output
Returns a list of matching MCP servers and A2A tools relevant to the query, with compressed capability descriptions (85% token reduction) and safety-filtered results via the Prompt-Guard firewall. May include endpoint URLs, tool names, supported operations, and routing metadata.
Example use cases
Discovering GitHub security audit tools
“Search across all indexed MCP servers for anything related to 'GitHub security audits' — I want to know which tools are available and what they can do.”
Finding company enrichment capabilities
“Look through the MCP and A2A tool directory for capabilities around 'company enrichment' or 'B2B lead data' — I need to pick the best tool to enrich a list of company names.”
Verifying a remote agent endpoint
“Can you check whether this endpoint URL is a valid, compliant MCP or A2A server? Here's the URL: https://someagent.example.com/mcp — I want to know if it passes the tool discovery index.”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/bundle-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools can handle a given capability, rather than hardcoding tool connections. Ideal for meta-agent orchestrators, swarm coordinators, or agent builders who want a single connection point to a broad tool ecosystem with built-in safety filtering and token-efficient responses.
Side effects
- Empty or vague query returns no meaningful results
- Query too broad may return too many loosely related tools
- Endpoint URL verification may time out if target server is unreachable
- Some MCP servers in the index may be stale or offline
- Prompt injection attempts in query are blocked by firewall, returning an error or sanitized response
