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://company-enrich.agentdiet.dev/v1/swarm-router)
Output
Returns a list of matched MCP servers or A2A tool endpoints relevant to the capability query, with compressed tool manifests (up to 85% token reduction) and metadata about each discovered tool, filtered through a Prompt-Guard firewall to prevent injection attacks.
Example use cases
Discovering SEC filing tools for agents
“Search the MCP swarm router for tools that can retrieve SEC filings — I need to find which agents or MCP servers in the index support that capability.”
Finding GitHub security audit agents
“Can you search the tool discovery router for any MCP servers or A2A agents that handle GitHub security audits or repository scanning?”
Routing query to email verification agent
“Use the swarm router to find me an MCP tool that does email verification — I want to connect through the single-router interface rather than managing individual endpoints myself.”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover tools across a large ecosystem of MCP servers and A2A agents without managing individual connections, especially when token budget is a concern (85% compression) or when you want a safety layer (Prompt-Guard) against prompt injection from external tool responses. Prefer over direct MCP connections when you don't know which specific server handles a capability.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability query
- Upstream MCP server unreachable causing partial result set
- Prompt injection attempt detected and blocked by Prompt-Guard firewall
- HTTP 402 payment required if x402 micropayment not included
