Lucid MCP Server and Tools

Connect your AI tools to Lucid to intelligently search for files, create visuals, and share with your team.

The Lucid Model Context Protocol (MCP) server is a cloud-hosted bridge between your Lucid documents and AI tools such as ChatGPT, Claude, Microsoft Copilot, and Cursor. Once connected, you can use natural language to search, retrieve, edit, summarize, and create Lucid documents from inside your AI client. Use of the Lucid MCP server is subject to the negotiated services agreement between the parties or Lucid's standard Terms of Service available at lucid.co/tos.

• Endpoint: https://mcp.lucid.app/mcp
• Transport: Streamable HTTP
• Auth: OAuth 2.0 with Dynamic Client Registration (DCR)
• Plans: Free, Individual, Team, and Enterprise. Not available on FedRAMP accounts.
• Marketplace listing: lucid.co/marketplace/e16391cc/lucid-mcp-server
• Setup guide: Integrate Lucid with AI tools using the Lucid MCP server

Skills

Skills

Skills are pre-built instructions that give AI clients (Claude, ChatGPT, Cursor, etc.) domain expertise for common Lucid workflows with the Lucid MCP Server. The full skill library lives in this repo's /skills folder. Download any .SKILL.md file and drop it into your MCP client's skills folder (e.g. .claude/skills/) to use it manually.

Agent Skills

Agent skills are skills that are directly built into the AI client plugins.You can describe what you want in plain language, and if a matching skill exists it's automatically invoked, or run one directly with a / command.

---

Cursor plugin

Install the Cursor plugin for bundled MCP config and a unified Lucid agent skill:

/add-plugin lucid

See cursor/README.md for Cursor-specific setup, skills, and example prompts.

Claude plugin

Once published in Anthropic's public marketplace, install the Lucid plugin with bundled MCP configuration and workflow guidance:

/plugin install lucid@claude-plugins-official

See claude/README.md for direct repository installation before marketplace acceptance, authentication, local development, and the plugin layout.

---

JSON config

Some clients require you to edit a JSON config file directly.

If your client supports the HTTP transport:

"Lucid Software": {

"type": "http", "url": "https://mcp.lucid.app/mcp" }

If your client does not support HTTP transport, use the mcp-remote Node.js package to forward stdio requests to the Lucid MCP server. Node.js must be installed.

"Lucid Software": {

"command": "npx", "args": ["-y", "mcp-remote", "https://mcp.lucid.app/mcp"] }

For admins: enable or disable the Lucid MCP server

Admins on Team and Enterprise accounts can control whether users can connect to the Lucid MCP server.

1. In your Lucid account, select Admin from the left-side panel.
2. Click Security in the left-side menu.
3. Select Feature controls.
4. Under MCP access, use the toggle next to Allow users to connect.
5. Confirm with Enable MCP or Disable MCP in the modal.

Granting access allows users to connect from any AI client. To restrict access to specific AI tools, you'll need to disable the Lucid MCP server at the account level.

Authentication & data handling

• Authentication uses OAuth 2.0 with Dynamic Client Registration (DCR).
• The Lucid MCP server can access any Lucid document you have permission to access within your account. It cannot access documents owned by users outside your account.
• The server acts as a pass-through — it does not retain document content, user prompts, or queries. Your credentials are never shared outside your Lucid account.
