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://polymarket-odds.agentdiet.dev/v1/swarm-router)
Output
Returns a structured list of matching MCP servers and A2A tools from the 500+ indexed endpoints, with token-compressed metadata about each tool's capabilities, along with prompt-guard firewall filtering applied to the results. For URL verification queries, returns compliance and reachability status of the specified endpoint.
Example use cases
Discovering domain OSINT tools for agents
“I need to find an MCP server or A2A tool in the swarm that can do domain OSINT — search for 'domain OSINT' and tell me what's available.”
Routing to token compression capability
“Search the swarm router for tools that support context compression or token reduction — I'm trying to cut down the token usage in my agent pipeline.”
Verifying a specific MCP endpoint
“Can you check if this MCP endpoint is valid and reachable through the swarm router? The URL is https://some-mcp-server.example.com/v1/tools”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which of 500+ MCP servers or A2A tools can handle a specific capability without knowing the exact endpoint URL in advance, or when you want a single authenticated proxy connection instead of managing individual tool connections. Particularly useful for agents that need to dynamically route tasks to the best available tool, compress token usage via the built-in 85% compression layer, or verify that a remote MCP/A2A endpoint meets compliance standards.
Side effects
- Query string too short or vague — no meaningful matches returned
- Specified endpoint URL is unreachable or not in index — returns empty or error
- Payment not processed (HTTP 402) — request blocked until x402 micropayment is completed
- Swarm index temporarily unavailable — service degradation on upstream MCP servers
- Query triggers prompt-guard firewall — request blocked as potentially adversarial
