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/broker/execute)
Output
Returns a list of matching MCP servers or A2A tool endpoints relevant to the query, with capability descriptions and routing metadata, compressed to minimize token usage. May include endpoint URLs, supported operations, and compliance status.
Example use cases
Discover tools for GitHub security audits
“Can you search the MCP tool directory for any servers or A2A agents that handle GitHub security auditing or code vulnerability scanning? I want to route my agent to the best one.”
Find an MCP server for context compression
“I need to find an MCP endpoint that does context compression — search the tool index for anything that reduces token usage or compresses prompts, and tell me what's available.”
Validate a specific A2A endpoint URL
“Can you verify whether this URL is a legitimate A2A or MCP tool: https://example-agent.dev/v1/execute — check if it's compliant and what capability it offers.”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to use for a given capability at runtime, rather than hardcoding a specific tool. Especially useful when building swarm architectures, when the required capability is not known in advance, or when you want a single connection point with built-in prompt-injection protection across a large tool catalog.
Side effects
- Empty or vague query returns no relevant results
- Queried endpoint URL is unreachable or malformed
- No matching MCP servers found for niche capability query
- Service returns generic 500 if broker index is unavailable
- Rate-limiting or payment failure if x402 quota exceeded
