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://mcp-compiler.agentdiet.dev/v1/swarm-router)
Output
Returns a list of matching MCP servers or A2A tool endpoints relevant to the query, with metadata about each tool's capabilities, potentially with compressed representations and safety-filtered through the Prompt-Guard firewall
Example use cases
Finding a GitHub security audit tool
“Search the swarm router for any available tools that can do GitHub repository security auditing — I want to find a safe-proxied MCP server I can route my agent through.”
Discovering DEX token intelligence tools
“Look up what DEX token intelligence or on-chain risk analysis tools are available in the MCP swarm index so I can pick the right one for my crypto agent.”
Routing to a context compression endpoint
“Can you search the A2A and MCP tool index for any endpoints that offer context compression? I want to reduce token usage in my agent pipeline.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to dynamically discover which MCP server or A2A agent tool supports a particular capability without maintaining your own index of 500+ servers; especially useful when you want a single connection with built-in safety filtering and token compression rather than managing multiple direct integrations
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability queries
- Downstream MCP server unavailable causing incomplete results
- Payment required error (HTTP 402) if x402 micropayment not attached
- Prompt injection attempts blocked by Prompt-Guard firewall returning sanitized or rejected results
