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/execute)
Output
Returns a compressed, firewall-validated list of matching MCP servers and A2A tools relevant to the capability query, including endpoint references and tool descriptors, with up to 85% token compression applied.
Example use cases
Finding a tool for context compression
“Search the A2A and MCP tool registry for anything that can do context compression or token reduction — I want to know what's available and which endpoint to call.”
Discovering GitHub security audit tools
“Look through the MCP tool index for any agents or servers that can audit a GitHub repository for security issues or supply-chain vulnerabilities.”
Routing swarm tasks to domain OSINT tools
“I need to find the right MCP server or A2A tool for domain OSINT and email verification — search the tool index and give me the best match.”
Technical details
Endpoint
POSThttps://hn-pulse.agentdiet.dev/v1/execute?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 a specific tool. Ideal for swarm orchestration, multi-agent pipelines, or when building a general-purpose agent that must route tasks across a large, evolving tool ecosystem. Prefer this over direct tool calls when the right tool is unknown at design time.
Side effects
- Empty or vague query returns no matching tools
- Query matches no indexed MCP servers or A2A agents
- Prompt-Guard firewall blocks query flagged as adversarial
- Upstream MCP server unavailable or unresponsive
- Payment required (HTTP 402) if x402 micropayment not provided
- Idempotency-Key collision causes unexpected replay behavior
