# Lucid MCP server

> Search, create, edit, summarize and share Lucidchart and Lucidspark documents and diagrams from your AI assistant.

- Listing: https://mcp.tc/i/lucid
- Connect: use the server's own URL `https://mcp.lucid.app/mcp` (OAuth sign-in at the server); clients connect to it directly. The listing link is a page, not an MCP endpoint.
- Type: remote (Streamable HTTP)
- Auth: OAuth sign-in
- Category: [Design, Websites & CMS](https://mcp.tc/c/design)
- Vendor: Lucid Software
- Homepage: <https://lucid.co/>
- Repository: <https://github.com/lucidsoftware/lucid-mcp-server>

## About

Connects an AI client to your Lucid account so you can search documents, summarize their contents and action items, and create diagrams from a natural-language prompt. It can also build org charts from CSV or text, generate UML sequence diagrams from PlantUML, edit, add or delete shapes, export documents as PNG, and share documents by email or by link with a chosen permission level.

The server is hosted by Lucid at https://mcp.lucid.app/mcp and uses Streamable HTTP. Users sign in with OAuth 2.0 (Dynamic Client Registration) and it can reach documents the signed-in user has permission to access. It is available on Free, Individual, Team and Enterprise plans, but not on FedRAMP accounts.

## What it can do

- Search Lucid documents for specific content
- Summarize documents and action items
- Create diagrams from a natural-language prompt
- Create org charts from CSV or text
- Generate UML sequence diagrams from PlantUML
- Edit, add or delete shapes in a document
- Share documents by email or create shareable links
- Export documents as PNG

## Example prompts

- "Show me all Lucid documents that talk about the website redesign project."
- "Summarize the action items in my Q4 Website Redesign Workflow document."
- "Create a diagram in Lucid that maps out a user authentication flow."
- "Create a view-only shareable link for my FY26 Q3 Product Roadmap document."

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http lucid https://mcp.lucid.app/mcp
```

2. Start Claude Code, type `/mcp`, pick **lucid** and choose **Authenticate**. A browser window opens for the Lucid Software sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Settings → Connectors** and click **Add custom connector**.

2. Name it **Lucid** and paste this URL:

```url
https://mcp.lucid.app/mcp
```

3. Click **Add**, then **Connect**, and sign in when Lucid Software asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Lucid&connectorUrl=https%3A%2F%2Fmcp.lucid.app%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://mcp.lucid.app/mcp` and click **Add**.

3. Click **Connect** and sign in when Lucid Software asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://mcp.lucid.app/mcp` as the server URL and choose **OAuth**. ChatGPT sends you to Lucid Software to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=lucid&config=eyJ1cmwiOiJodHRwczovL21jcC5sdWNpZC5hcHAvbWNwIn0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "lucid": {
      "url": "https://mcp.lucid.app/mcp"
    }
  }
}
```

Cursor shows **Needs login** next to the server. Click it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=lucid&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.lucid.app%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"lucid","type":"http","url":"https://mcp.lucid.app/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "lucid": {
      "type": "http",
      "url": "https://mcp.lucid.app/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "lucid": {
      "serverUrl": "https://mcp.lucid.app/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add lucid --url https://mcp.lucid.app/mcp
codex mcp login lucid
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.lucid]
url = "https://mcp.lucid.app/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http lucid https://mcp.lucid.app/mcp
```

Then, inside Gemini CLI, run `/mcp auth lucid` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "lucid": {
      "type": "http",
      "url": "https://mcp.lucid.app/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://mcp.lucid.app/mcp`.
