Connect to Nolt's MCP Server

Overview

Nolt exposes a remote MCP server that lets AI assistants read and act on Nolt boards (posts, comments, statuses, votes, etc.) on a user's behalf.

• MCP URL (same for every client): https://nolt.io/mcp
• Auth: OAuth 2.0. The user signs in with their normal Nolt account and approves the connecting app.

Dynamic client registration is disabled — only pre-approved apps can obtain a token. Because of this, every client below needs both values entered explicitly during setup: the MCP URL and its own Client ID.

Claude (claude.ai / Claude Desktop)

1. Go to Settings → Connectors.
2. Click Add custom connector.
3. Enter the MCP URL: https://nolt.io/mcp.
4. Open Advanced settings and enter the Client ID: nolt-claude-web.
5. Save, then click Connect and complete the OAuth sign-in with your Nolt account.

Claude Code

Add the server, then supply the Client ID when prompted / via config — the exact flag or config field may vary by version, so check claude mcp add --help if the URL-only form below doesn't ask for it:

claude mcp add --client-id nolt-claude-code --transport http nolt https://nolt.io/mcp

Client ID: nolt-claude-code

Then start Claude Code and run /mcp to complete the OAuth sign-in with your Nolt account.

ChatGPT

1. Visit the Nolt plugin page and click Install.
2. Follow the authorization prompt to log in to your Nolt account and grant the requested permissions.
3. Open a ChatGPT conversation, select Nolt using the + menu or mention @Nolt, and start interacting with your workspace.

Codex

1. Launch Codex using the Codex CLI.
2. Open the plugin browser by running /plugins in Codex CLI. Search for Nolt. Select the Nolt plugin and click Install.
3. Follow the authorization prompt to log in to your Nolt account and grant the requested permissions.
4. Start Using Nolt.

Start a new Codex session and ask questions or perform actions using natural language.

Visual Studio Code

Add an entry to your user mcp.json (Command Palette → MCP: Open User Configuration) or to a workspace .vscode/mcp.json:

{
  "servers": {
    "nolt": {
      "type": "http",
      "url": "https://nolt.io/mcp",
      "auth": {
        "clientId": "nolt-vs-code"
      }
    }
  }
}

VS Code will prompt you to sign in with your Nolt account the first time an agent uses the server.

Cursor

Add an entry to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project-level):

{
  "mcpServers": {
    "nolt": {
      "url": "https://nolt.io/mcp",
      "auth": {
        "CLIENT_ID": "nolt-cursor"
      }
    }
  }
}

Reload MCP servers in Cursor's settings and authorize with your Nolt account when prompted.

Troubleshooting

"unauthorized_client" / registration errors: each app must use its exact Client ID from the table above — a missing or mistyped Client ID looks like a generic auth failure in most of these apps. If you're using a client that isn't listed here, contact us and we'll get it added.
