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/swarm-router)
Output
A list of matching MCP servers or A2A agent tools relevant to the capability query, with token-compressed metadata about each endpoint, routing details, and Prompt-Guard firewall protection applied to the results.
Example use cases
Discovering tools for financial data
“Find me any MCP servers or A2A agent tools in the swarm router that handle SEC filings or financial document retrieval — I need to know what's available before I wire up my agent.”
Routing agent to GitHub audit capability
“Search the swarm router for available tools that can do GitHub security audits or code repo analysis — I want to pick the best one to connect my agent to.”
Finding email verification endpoints
“Can you query the swarm router to find any MCP or A2A endpoints that support email verification or domain OSINT? I need to pick one for my lead enrichment pipeline.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/swarm-router?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 for a given capability, rather than hardcoding a specific tool. It is especially useful for multi-agent orchestration or swarm architectures where the right tool may vary by task and the agent needs a single connection point to a large index rather than maintaining hundreds of individual integrations.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or overly specific capability queries
- Index may not reflect newly added MCP servers in real time
- Rate limiting or 402 payment required if x402 quota exceeded
- Malformed endpoint URL when used in verification mode returns error
