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/a2a-router)
Output
Returns a structured list of matching MCP servers or A2A tools relevant to the query, with metadata about each tool including capabilities, connection details, and safety-filtered (Prompt-Guard) results. Token-compressed to reduce overhead by up to 85%.
Example use cases
Finding a GitHub security audit tool
“Search the agent tool network for any MCP server or A2A tool that can do GitHub repository security audits — I want to know what's available and how to connect to it.”
Routing to a domain OSINT capability
“Find me an MCP tool in the registry that specializes in domain OSINT or WHOIS lookups — I need to run background checks on a few suspicious domains.”
Discovering token-compressed context tools
“I want to find any tools in the MCP network that support context compression — specifically ones that can shrink my prompt context before sending it to a model.”

Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover or route to one of many MCP or A2A tools without maintaining separate integrations for each. It is especially useful for swarm architectures, agent orchestration pipelines, or when you need a safety-filtered (prompt injection protected) proxy layer over a large tool ecosystem.
Side effects
- Empty result set if no tools match the query string
- Timeout or 402 payment required if micropayment not completed
- Prompt-Guard firewall blocks queries flagged as injection attempts
- Malformed query (empty string) rejected due to minLength:1 constraint
- Unavailable backend MCP servers may not appear in results
