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/workflows/execute)
Output
Returns a list of matching MCP servers or A2A tool endpoints relevant to the capability query, with metadata about each tool, along with routing recommendations. Output is compressed to reduce token usage and filtered through a prompt-injection firewall.
Example use cases
Finding a tool for SEC filings
“Find me an MCP server or A2A tool that can pull SEC filings and financial disclosures — search the index for anything related to SEC or EDGAR data.”
Discovering github security audit tools
“Search across the indexed MCP servers for tools that do GitHub security audits or code vulnerability scanning — I want to know what's available before I pick one.”
Routing to a company enrichment agent
“I need to enrich company data — find me the best available A2A tool or MCP endpoint in your index that handles B2B lead enrichment or company profile lookup.”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which tool or MCP server to call for a given capability, rather than hardcoding a specific API. Especially useful in swarm or orchestration contexts where the right downstream tool is not known in advance, or when you want a single firewall-protected proxy entry point across 500+ indexed services.
Side effects
- Empty or too-vague query returns no meaningful matches
- Query for a niche capability not covered by indexed servers returns empty results
- Endpoint URL verification fails if the target is offline or non-compliant
- Overly broad query returns too many results without useful ranking
- Service may return a 402 Payment Required if the $0.01 per-call fee is not satisfied
