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://serp-extract.agentdiet.dev/v1/agent-router)
Output
Returns a compressed, token-optimized list of matching MCP servers and A2A tools relevant to the capability query, filtered through the Prompt-Guard firewall, including tool descriptions, endpoint URLs, and compatibility metadata
Example use cases
Discover tools for GitHub security audits
“Search the agent-router for any MCP servers or A2A tools that can run GitHub security audits — I want to see what's available and pick the best one for my pipeline.”
Verify a specific MCP endpoint is compliant
“Can you check whether this endpoint URL is listed and verified in the agent-router index: https://some-mcp-server.example.com/v1/tools — I want to confirm it's safe to use.”
Find context-compression tools for swarm agents
“I'm building a multi-agent swarm and I need to find MCP tools that support context compression — search the router index for any that offer token reduction features.”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/agent-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover the right MCP server or A2A tool for a task at runtime, especially in multi-agent swarms where tool selection is automated. Prefer this over hardcoding tool URLs when the tool landscape changes frequently, or when you need firewall-filtered, token-compressed tool metadata to minimize context usage.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability queries
- Endpoint URL verification returns not-found if URL is not indexed
- Rate limiting or payment failure if x402 payment not included
- Malformed query may return empty or irrelevant results
