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://defi-yield.agentdiet.dev/v1/swarm-router)
Output
Returns a compressed list of matching MCP servers and A2A tools relevant to the query, including endpoint metadata, capability descriptions, and safety signals from the Prompt-Guard firewall, all encoded with 85% token compression.
Example use cases
Finding tools for on-chain risk analysis
“I need to find MCP servers or A2A tools that can do on-chain risk analysis for DeFi tokens — can you search the swarm router for that capability?”
Discovering email verification agents
“Search the tool discovery router for any MCP endpoints or agents that handle email deliverability verification and DMARC checks.”
Verifying a specific endpoint URL
“Can you check the swarm router to verify whether this endpoint URL is indexed and safe to use: https://some-mcp-server.example.com/v1/tool?”
Technical details
Endpoint
GEThttps://defi-yield.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 delegate a task to, especially when the full ecosystem of available tools is unknown. It is ideal for meta-orchestration layers, swarm agents, and agent pipelines that need to route capability queries across 500+ tools with minimal token overhead and built-in prompt injection protection.
Side effects
- Empty query string returns validation error
- No matching tools found for niche capability query returns empty result set
- Endpoint URL verification for unlisted or unknown URLs may return no match
- Rate limiting or payment failure (x402) blocks the request
- Malformed query may return irrelevant results
