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/mesh/dispatch)
Output
Returns a structured object listing matching MCP servers or A2A tools relevant to the query, with compressed tool descriptions (up to 85% token reduction), firewall-filtered results from the Prompt-Guard layer, and routing metadata for downstream dispatch.
Example use cases
Discovering tools for SEC filings
“Search the MCP mesh for any tools that can pull or parse SEC filings — I need to find an available agent tool that handles financial disclosure data.”
Finding GitHub security audit tools
“Can you search the A2A and MCP tool index for anything that does GitHub security audits or code vulnerability scanning? I want to route my repo checks through whatever's available.”
Verifying a live agent endpoint
“I have this endpoint URL — https://some-agent.example.com/api/dispatch — can you check against the MCP mesh whether it's a real, compliant A2A endpoint or just a stub?”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hardcoding a specific tool. Especially useful for multi-agent swarm orchestration, tool fallback routing, or when the agent needs to search a broad ecosystem of 500+ tools with compressed output to save tokens.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability query returns empty result set
- Endpoint URL verification may time out if the remote server is unresponsive
- Rate limiting or payment failure (x402) may block access
- Overly broad queries may return noisy or low-relevance results
