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://mcp-compiler.agentdiet.dev/v1/workflows/rag-context-sanitizer)
Output
Returns a structured object listing matching MCP servers and A2A tools for the queried capability, with 85% token-compressed context and prompt-guard-filtered metadata, or endpoint verification status if a URL was supplied.
Example use cases
Discovering tools for GitHub security audits
“Search the MCP meta-router for tools that handle GitHub security auditing — I need to find which servers in the index can do that so I can route my agent there.”
Verifying an MCP endpoint URL
“Can you verify whether https://some-agent.example.com/mcp is a valid, compliant MCP or A2A endpoint by running it through the tool discovery index?”
Finding company enrichment tools for a B2B agent
“Search the swarm router index for 'company enrichment' tools — I'm building a B2B lead pipeline and need to know which MCP servers handle that capability.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/workflows/rag-context-sanitizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover which MCP servers or A2A tools support a given capability without connecting to each one individually, or when verifying that a specific endpoint URL is MCP/A2A compliant. It is especially useful when token budget is constrained, thanks to 85% compression, and when prompt injection safety is a concern via the built-in Prompt-Guard firewall.
Side effects
- Missing or empty 'query' parameter returns a validation error
- Query with no matching tools returns empty result set
- Unrecognized or unreachable endpoint URL returns verification failure
- Service unavailability or upstream index timeout returns 5xx error
- Overly broad queries may return too many low-relevance results
