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://whale-momentum.agentdiet.dev/v1/workflows/rag-context-sanitizer)
Output
Returns a compressed, Prompt-Guard-filtered list of matching MCP servers or A2A tools relevant to the query, including tool descriptors and routing metadata, with up to 85% token reduction compared to raw index responses.
Example use cases
Routing agent to SEC filing tool
“Find me an MCP server in the swarm index that can pull SEC filings — I want to route my research agent to the right tool automatically.”
Discovering GitHub security audit tools
“Search the A2A tool registry for anything that does GitHub security audits or code scanning so I can wire it into my CI pipeline agent.”
Verifying a live MCP endpoint URL
“Can you check whether this endpoint URL — https://some-agent.example.com/mcp — is actually indexed and live in the tool discovery system?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/workflows/rag-context-sanitizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call next, especially when the available tool set is large and token budget is constrained. It is best suited for swarm-style orchestration where the agent does not know in advance which downstream tool to invoke. Prefer alternatives if you already know your target endpoint and simply need to call it directly.
Side effects
- Empty query string returns 400 validation error
- No matching tools found returns empty result set
- Endpoint URL verification returns not-found if URL is not indexed
- Upstream MCP server unavailability may cause partial results
- Payment required (HTTP 402) if x402 payment header is missing or insufficient
