Unplain MCP

The Unplain MCP server allows AI assistants to connect to Unplain's design engine via OAuth or API key. It enables agents to create publish-ready PDFs (ebooks, reports, lead magnets) from text, Markdown, or public URLs, manage Brand Themes, edit content atomically, and export designed documents with covers and pagination.

Endpoint and access

OAuth sign-in: the first time you connect, your client opens the vendor's own authorization prompt in a browser.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http unplain-mcp https://app.unplain.io/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add unplain-mcp --url https://app.unplain.io/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable unplain-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "unplain-mcp": {
      "url": "https://app.unplain.io/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "unplain-mcp": {
      "type": "streamableHttp",
      "url": "https://app.unplain.io/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start unplain-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "unplain-mcp": {
      "type": "http",
      "url": "https://app.unplain.io/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http unplain-mcp https://app.unplain.io/api/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://app.unplain.io/api/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "unplain-mcp": {
      "serverUrl": "https://app.unplain.io/api/mcp"
    }
  }
}
