Doesn’t work in LM Studio

[quinncomendant]

Have you gotten this working in LM Studio?

I'm getting the following error when trying to use this MCP in LM Studio. I'm not sure if its an issue with LM Studio, or mcp-wayback-machine. Feel free to close this issue if its off topic.

I installed like this:

npm install -g mcp-wayback-machine

I've added it to LM Studio's mcp.json file like this:

{
  "mcpServers": {
    "wayback-machine": {
      "command": "node",
      "args": [
        "/opt/homebrew/lib/node_modules/mcp-wayback-machine/dist/index.js"
      ]
    }
  }
}

When I load the MCP in LM Studio, this error appears:

Failed to load plugin tools: [ { "code": "invalid_literal", "expected": "object", "path": [ "tools", 0, "inputSchema", "type" ], "message": "Invalid literal value, expected \"object\"" }, { "code": "invalid_literal", "expected": "object", "path": [ "tools", 1, "inputSchema", "type" ], "message": "Invalid literal value, expected \"object\"" }, { "code": "invalid_literal", "expected": "object", "path": [ "tools", 2, "inputSchema", "type" ], "message": "Invalid literal value, expected \"object\"" }, { "code": "invalid_literal", "expected": "object", "path": [ "tools", 3, "inputSchema", "type" ], "message": "Invalid literal value, expected \"object\"" } ]
