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/execute)
Output
Returns a structured object listing matching MCP servers or A2A tools relevant to the query, with tool descriptions compressed by up to 85% for token efficiency, filtered through a Prompt-Guard firewall for safety, and including routing metadata needed to connect to or invoke the matched endpoints.
Example use cases
Finding context compression tools
“Search for MCP tools that support context compression — I want to reduce token usage in my agent pipeline by at least 80%.”
Routing to GitHub security audits
“Look up which A2A or MCP tools in the index handle GitHub security auditing so I can plug one into my CI/CD workflow.”
Discovering B2B lead enrichment agents
“Search the tool registry for anything that does company enrichment or B2B lead data so my sales automation agent can call the right endpoint.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool URL. It is especially valuable when building swarm architectures, when the required capability is not known at design time, or when token budget is tight (85% compression). Prefer alternatives if you already know the exact MCP server URL and just need to invoke it directly.
Side effects
- Empty query string returns validation error (minLength:1 not met)
- No matching tools found for obscure or overly specific queries
- Prompt-Guard firewall may suppress results containing injection-like patterns
- Remote MCP servers in the index may be offline or stale
- HTTP 402 payment required if x402 credits are exhausted
- Highly ambiguous queries may return irrelevant tool matches
