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/swarm-execute)
Output
Returns matched MCP server and A2A tool records relevant to the query, with token-compressed metadata, endpoint URLs, capability descriptions, and safety/compliance signals from the Prompt-Guard firewall layer.
Example use cases
Discover tools for SEC filing retrieval
“Find me MCP servers or A2A tools that can pull SEC filings — search for 'sec filings' in the tool index and give me the best matches.”
Route agent query to compression tool
“I need a tool that does context compression for my agent pipeline — search the swarm router for 'context compression' and tell me what's available.”
Verify a remote MCP endpoint
“Can you check if the URL https://some-mcp-server.example.com is a valid, compliant MCP endpoint by running it through the tool discovery router?”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/swarm-execute?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 given capability at runtime, rather than hardcoding tool references. Especially useful for multi-agent swarm orchestration, when the tool landscape is large or changing, or when prompt-injection safety screening of tool responses is required.
Side effects
- Empty query string returns validation error
- No tools found matching the query returns empty result set
- Queried endpoint URL is unreachable or non-compliant, returns error status
- Token budget exceeded for large result sets
- Rate limit or 402 payment required if prepaid credits are exhausted
