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-broker)
Output
Returns a compressed, Prompt-Guard-filtered list of matching MCP servers and A2A tools relevant to the query, including tool metadata, routing recommendations, and capability descriptions — with up to 85% token compression applied to the response.
Example use cases
Routing agent to right MCP tool
“My agent needs to do GitHub security audits — can you search the MCP index and find which tool or server I should route it to?”
Discovering context compression tools
“I'm trying to reduce token usage in my agent pipeline — search the tool index for anything that does context compression or web distillation.”
Verifying a known safe endpoint
“Before I connect my agent to this endpoint URL, can you check if it's indexed as a known safe tool in the MCP directory?”
Technical details
Endpoint
POSThttps://hn-pulse.agentdiet.dev/v1/x402-broker?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding tool URLs. Ideal for swarm architectures that need to route tasks to specialized tools at runtime. Prefer this over manually curating tool lists when operating across 500+ potential tools, or when you need Prompt-Guard firewall protection on tool responses before passing them to downstream agents.
Side effects
- Empty or vague query returns no matches or low-relevance results
- Prompt-Guard firewall blocks queries containing injection patterns
- Unknown or unindexed endpoint URL returns no verification result
- Rate limiting or 402 payment failure if x402 payment is not provided
- Malformed query (minLength not met) returns validation error
