Claude Code

Add to your .mcp.json or project settings:

{
  "mcpServers": {
    "kremis": {
      "command": "/path/to/kremis-mcp",
      "env": {
        "KREMIS_URL": "http://localhost:8080"
      }
    }
  }
}

Manual Testing

# Start the Kremis server first
kremis server

# In another terminal, run the MCP server
KREMIS_URL=http://localhost:8080 ./target/release/kremis-mcp

The MCP server communicates via stdin/stdout using JSON-RPC. It will wait for MCP protocol messages.
