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://mesh.agentdiet.dev/v1/swarm-router)
Output
Returns a token-compressed (up to 85% compression) list of matching MCP servers and A2A tools relevant to the query, including capability descriptors and endpoint metadata, after passing through the Prompt-Guard firewall to filter unsafe or injected content.
Example use cases
Discover SEC filing tools for finance agent
“Search the swarm router for any MCP servers or A2A tools that can pull SEC filings — I'm building a finance research agent and need to find what's available.”
Find prompt injection firewall tools
“Can you query the swarm router for tools related to 'prompt injection firewall' or 'jailbreak detection'? I want to see what's indexed before I pick one for my pipeline.”
Verify a specific endpoint URL before use
“Before I add this endpoint to my agent, can you run its URL through the swarm router to verify it's a legitimate, indexed MCP tool?”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hard-coding a specific tool. Especially valuable when building meta-agents or orchestrators that need to route tasks to the best available tool at runtime. Prefer this over manually curating a tool list when you need breadth (500+ indexed tools) and safe delivery (firewall included).
Side effects
- Empty or vague query returns no matches or overly broad results
- URL verification for unindexed endpoints returns not-found
- Prompt-Guard firewall may block queries that pattern-match injection attempts
- 402 payment required if x402 credits are not attached
- Timeout if swarm router is querying a large number of backend MCP servers simultaneously
