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://workflows.agentdiet.dev/v1/swarm-execute)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with compressed metadata about each endpoint's capabilities, along with safety/firewall status from the Prompt-Guard layer
Example use cases
Discovering tools for GitHub security audits
“Search the MCP tool index for anything related to GitHub security scanning or code auditing — I want to find available agents or servers I can route that kind of work through.”
Finding context compression MCP servers
“Can you query the swarm router for MCP servers that support context compression or token reduction? I'm trying to cut down on token usage in my agent pipeline.”
Verifying a specific endpoint is safe to use
“Check if this endpoint URL is indexed and verified in the swarm router — I want to confirm it's safe to proxy through before I start using it: https://some-mcp-server.example.com/tool”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single-connection gateway to discover and route across a large ecosystem of MCP servers and A2A tools without managing individual connections, especially when token efficiency and prompt injection safety are priorities. Prefer this over direct MCP server connections when you don't know which specific tool handles your capability or when you need a vetted, compressed meta-index of available agents.
Side effects
- Missing or empty query string returns a 400 validation error
- No matching tools found for obscure or overly specific queries
- Payment required (HTTP 402) if x402 micropayment header is absent or malformed
- Prompt injection attempt blocked by Prompt-Guard firewall with rejection response
- Upstream MCP server unavailable causes partial or empty results
