VS Code - SeeSaw Developer

Configure

Create .vscode/mcp.json in your workspace. Note that VS Code uses servers (not mcpServers), and supports prompted inputs so the key never sits in the file:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "seesaw-key",
      "description": "SeeSaw API key (sspat_…)",
      "password": true
    }
  ],
  "servers": {
    "seesaw": {
      "type": "http",
      "url": "https://api.seesaw.fun/mcp",
      "headers": {
        "Authorization": "Bearer ${input:seesaw-key}"
      }
    }
  }
}

VS Code prompts for the key on first start and stores it securely.

Verify

Open the Chat view in agent mode and check the tools picker — the seesaw server should list 14 tools. Then try:

Who’s on top of the SeeSaw global leaderboard?

Troubleshooting

Symptom	Likely cause
Server won’t start	Using `mcpServers` instead of `servers`, or JSON syntax error
Auth error	Wrong key entered at the prompt — run “MCP: Reset cached inputs” from the command palette
Tool errors mentioning retry	Rate limited — see Rate limits
