Overview

Description from the maker (original English)

Lucid’s connector creates diagrams, searches, edits, shares, and retrieves docs to summarize.

Common questions

Is Lucid safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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

What you can do

With the Lucid MCP server connected, you can prompt your AI tool to:

Search Lucid documents for specific content
Summarize document details and action items
Create shareable links with the permission level you specify
Share documents with collaborators by email
Create diagrams from a natural-language prompt
Create org charts from a CSV file or text
Edit, add, or delete shapes in an existing document
Generate UML sequence diagrams from PlantUML markup
Export documents as PNG
Fetch images attached to shapes in a document
Convert visual output from Claude into a Lucid document

Example prompts

"Show me all Lucid documents that talk about the website redesign project."

"Find the 'Q4 Website Redesign Workflow' document in Lucid, and give me a summary of action items."

"Create a diagram in Lucid that maps out a user authentication flow."

"In my Lucid IT Escalation Process document, update all decision blocks to a red fill with bold white text."

"Create a shareable link with view-only permissions for my 'FY26 Q3 Product Roadmap' document in Lucid."

Supported clients

The Lucid MCP server is compatible with any MCP client. For one-click setup, Lucid offers dedicated connectors for ChatGPT and Claude:

For other clients, follow the MCP-setup docs for your tool of choice and use the server URL https://mcp.lucid.app/mcp:

Client	Setup docs
ChatGPT	Developer mode
Claude desktop	Local MCP servers on Claude desktop
Claude web	Custom connectors using remote MCP
Claude Code	Installing MCP servers
Microsoft Copilot Studio	Add an existing MCP server
GitHub Copilot	Extend Copilot Chat with MCP
Cursor	MCP context; install via `/add-plugin lucid` — see Cursor plugin below
Windsurf	Configuring your first MCP server

This is not an exhaustive list — the Lucid MCP server works with any MCP-compatible client.

AI tools you set up with the Lucid MCP server are Non-Lucid Applications (as defined in our Terms of Service). Your use of these AI tools is subject to the agreement between you and the third-party provider.

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.

In your Lucid account, select Admin from the left-side panel.
Click Security in the left-side menu.
Select Feature controls.
Under MCP access, use the toggle next to Allow users to connect.
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.
