Lucid MCP Server

Official Lucid MCP server. Search Lucidchart and Lucidspark documents, summarize them, generate diagrams from prompts, and share files from your AI client.

Connect (Remote Server) Docs

Overview

The Lucid MCP server is an official, Lucid-hosted remote MCP endpoint that connects AI clients to a user's Lucidchart and Lucidspark content. Launched in November 2025, it lets agents search documents across a workspace, return summaries and key takeaways, create new diagrams from a description or dataset, and share documents or generate share links without leaving the AI tool. An Edit Document capability for in-place AI edits to existing Lucid documents was added in 2026.

The server is provider-hosted at https://mcp.lucid.app/mcp and uses OAuth with Dynamic Client Registration (DCR), so users authenticate through their existing Lucid account rather than managing API keys. Lucid account admins enable MCP access for their account in the Admin Panel before end users can connect. Once enabled, the server works with any MCP-compatible client, including Claude (web and desktop), ChatGPT, Microsoft Copilot, GitHub Copilot, Cursor, and Windsurf.

Because it is an official integration, it inherits Lucid's existing permission model: agents can only see and act on documents the connected user already has access to. This makes it suitable for enterprise deployments where visual content like architecture diagrams, process maps, org charts, and brainstorming boards needs to be reachable from an AI workflow without bypassing Lucid's access controls.

Tools

Tool	Description
`Search documents`	Find Lucidchart diagrams and Lucidspark boards across the user's library using a natural language query.
`Summarize document`	Generate a summary or extract key takeaways from a Lucid document inside the AI client.
`Create diagram`	Generate a new Lucid diagram from a textual description or a provided dataset (for example, a process diagram, flowchart, or org chart).
`Edit document`	Apply AI-described changes to an existing Lucid document; the server executes the edits in Lucid.
`Share document / create share link`	Share a Lucid document with teammates by email with a specified permission level, or generate a shareable link with custom access rights.

Setup Guide

Prerequisites

A Lucid account (Lucidchart or Lucidspark).
An account admin must enable the MCP server for the Lucid account via the Admin Panel.
An MCP-compatible client (Claude, ChatGPT, Cursor, VS Code, Windsurf, Microsoft Copilot, etc.).

Server URL

https://mcp.lucid.app/mcp

Authentication is handled via OAuth with Dynamic Client Registration (DCR). You do not need to register an OAuth app or whitelist URLs in Lucid's Developer Portal; the consent flow runs automatically the first time you connect.

Claude Desktop / Claude.ai (custom connector)

In Claude, add a custom connector with:

Name: Lucid
Remote MCP server URL: https://mcp.lucid.app/mcp

Then click Connect and complete the Lucid OAuth flow when prompted.

Cursor / Windsurf / VS Code style config

Most MCP clients accept a remote server entry like:

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

Restart the client after adding the entry, then run the OAuth flow when the client first reaches the server.

Verification

Once connected, prompt the agent with something like "Find my Lucid diagrams about onboarding" or "Create a Lucid flowchart for a refund process." If the server is wired up correctly the agent will call the appropriate Lucid tools and return results or a document link.

Use Cases

Search a workspace's Lucidchart and Lucidspark library by description ("find the diagram showing our payments architecture") and open the most relevant doc.
Summarize a long process map or org chart inside the AI chat so a teammate can get up to speed without opening Lucid.
Turn a conversation or a structured dataset into a new Lucid diagram (flowchart, swimlane, org chart) directly from the LLM.
Apply AI-described edits to an existing Lucid document, such as renaming nodes, adding decision branches, or reordering steps.
Generate share links or email a Lucid doc to teammates with a chosen permission level without leaving the AI client.

Example Prompts

"Find any Lucidchart diagrams about our customer refund workflow and summarize the main steps."
"Create a Lucid flowchart for a new employee onboarding process with steps for IT, HR, and manager intro."
"Generate an org chart in Lucid from this CSV of team members and managers."
"Open my Lucid architecture diagram and add a new service called 'fraud-detector' connected to the payments service."
"Share the 'Q3 launch plan' Lucidspark board with alex@acme.com as an editor and send me the link."

Pros

Official, Lucid-hosted server with no self-hosting or API key management required.
Inherits Lucid's native permission model via OAuth, so agents only see documents the user can already access.
Covers the full read-create-edit-share loop, not just read-only access.
Works across all major MCP clients (Claude, ChatGPT, Copilot, Cursor, Windsurf).

Limitations

Requires a Lucid account admin to enable MCP for the workspace before end users can connect.
The exact MCP tool surface and parameter schemas are not publicly documented in detail outside the client's tool list.
Some capabilities (such as the Edit Document API) shipped after the initial release, so older write-style features may be limited depending on the account's plan.

Alternatives

Figma MCP server for design files, frames, and components instead of diagrams.
Miro and community Miro MCP servers for whiteboarding and visual collaboration.
smartzan63/lucid-mcp-server, a community open-source MCP server that exports Lucid documents as PNGs for multimodal LLM analysis.
