OpenChartsruns apublic, hostedModel Context Protocol(MCP) serverthat puts the whole OpenCharts product inside any MCP-compatible AI client. Connect once with an API key and your assistant can build and manage real OpenCharts projects on your behalf — flowcharts, whiteboards, notes, presentations, spreadsheets (Theo Sheets), Kanban + calendar boards, full websites & apps (Code Canvas), automations (Theo Agents), songs (Theo Symphony), and images & video (Theo Media) — all powered by Theo, the OpenCharts AI. When building a site or app, your assistant can generate real imagery and video clips inline and drop the returned URLs straight into the code instead of leaving placeholders.

Want to connect in under a minute? Use the in-app guide atopencharts.com/help/mcp-serveror the setup page atopencharts.com/theo-agents/mcp.
- Create an API keyatopencharts.com/theo-agents/mcp. Copy it immediately — the full key is shown only once.
- Add the serverto your AI client using the matchingconfig snippet below, replacing{{YOUR_API_KEY}}with your key.
- Verifythe connection by asking your assistant to call thewhoamitool — it should return your OpenCharts account.

The server works with any MCP-compatible client. Copy the matching snippet and swap in your API key. Prefer to let your assistant wire it up? Thehelp pagehas a one-paste "AI setup prompt" for every client below.

The server exposes59 toolsacross 11 groups. Tools that use Theo AI or generation consume AI credits.

Resources provide read-only context an AI client can retrieve without calling a tool.

Every request is authenticated by your API key and acts on your own OpenCharts account. Because the server is hosted, the tool surface stays current automatically — no client updates required. Tools that use Theo AI or generation (for exampleask_theo,extract_flowchart,generate_code_canvas,build_agent,create_song,generate_image,generate_video) consume AI credits from your plan.
