      "env": {},
      "isActive": true,
      "type": "sse"
    }

}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "graphml-gexf-edge-list-network-converter",
    "arguments": {
  "networkInput": "source,target,weight,directed,relation\nalice,bob,3,true,knows\nbob,carol,1,true,works-with\ncarol,alice,2,true,follows",
  "networkFile": "https://example.com/file.ext",
  "inputFormat": "edge-list",
  "outputFormat": "graphml",
  "directedMode": "preserve"
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).

File parameters accept a public file URL only (https://…). Local paths, data: URIs, and Base64 strings are not supported.
