MCP Server for AI Agents
AI agents can create full Gantt chart projects from scratch, iterate on them, and generate a read-only public view and SVG — all via MCP.
When the plan is ready, import it into your Instagantt account with one click.
How It Works
Everything an agent can do
Agents create standalone projects, iterate on them, and produce shareable outputs.
Create Projects from Scratch
Agents build full Gantt charts from a text description — phases, tasks, timelines, and dependencies, all generated without an existing Instagantt account.
Iterate & Refine
Add, update, reorder, and delete tasks. Adjust dates, dependencies, and structure through conversation until the plan is right.
Public View
Every project gets a read-only public URL — share it with stakeholders for instant, no-login access to the Gantt chart.
SVG Export
Generate a vector SVG of the Gantt chart, ready to embed in docs, presentations, or any reporting tool.
Import to Instagantt
When the plan is ready, import it into your Instagantt account with one click to continue managing it with the full app.
Works With Any Agent
Compatible with Claude, GPT, Gemini, open-source models — any agent that speaks MCP.
Three steps to agent-powered PM
Add the MCP server
Add the Instagantt MCP server to your agent's config — one URL, no account required to start creating.
Describe your project
Tell the agent what you need — it builds a full Gantt chart with tasks, phases, and dependencies. Iterate until the plan is perfect.
Share or import
Get a public read-only URL and SVG to share instantly, or import the project into your Instagantt account to keep managing it.
Connect Instagantt to your Claude client
The Instagantt MCP server is remote and needs no API key or sign-in. Pick your client below — setup takes under a minute.
Claude Code (CLI)
Add the server with one command, from any project.
- 1
In your terminal, run this command to register the Instagantt server (HTTP transport, no key required):
terminalclaude mcp add --transport http instagantt https://ai.instagantt.com/mcp - 2
Confirm it connected — you should see “instagantt … ✔ Connected”:
terminalclaude mcp list - 3
Start Claude Code and ask it to build a Gantt chart. Type /mcp anytime to see the server and its tools. To share it with your team, add --scope project and commit the generated .mcp.json; to remove it, run claude mcp remove instagantt.
Claude Desktop
Add Instagantt as a custom connector — no terminal needed.
- 1
Open Claude Desktop and go to Settings → Connectors.
- 2
Scroll to the bottom of the list and click “Add custom connector”.
- 3
Name it “Instagantt”, paste the Remote MCP server URL below, leave the OAuth fields blank (none needed), and click Add:
Remote MCP server URLhttps://ai.instagantt.com/mcp - 4
In any chat, click the “+” in the message box → Connectors → toggle Instagantt on. Its tools now appear in the tools menu, ready to use.
Custom connectors are available on Free, Pro, Max, Team, and Enterprise plans (Free is limited to one). On an older Claude Desktop without the Connectors menu, you can instead bridge the remote server locally with “npx mcp-remote https://ai.instagantt.com/mcp” in claude_desktop_config.json (Settings → Developer → Edit Config).
Cursor & other MCP clients
Any MCP-compatible client works. Add this remote HTTP server to its config:
{
"mcpServers": {
"instagantt": {
"type": "http",
"url": "https://ai.instagantt.com/mcp"
}
}
}What the MCP server exposes
Two tools, no authentication required. Dates use YYYY-MM-DD; dependencies are finish-to-start.
create_gantt_chart
Generates a professional, interactive Gantt chart from structured project data and returns shareable URLs.
| Parameter | Type | Required | Description |
|---|---|---|---|
| title | string | Yes | The project/chart title displayed in the header. |
| sections | array | Yes | Top-level groups (project phases). Each section has a name and an array of tasks. |
| sections[].tasks[] | object | Yes | Each task: id, name, start and due dates (YYYY-MM-DD), optional predecessors (finish-to-start dependency IDs), assigned users ({id, name}), and one level of subtasks. |
Returns: A public snapshot URL of the interactive chart, an SVG image URL, a JSON URL with the full project data, and a chart ID + passcode for later changes.
delete_gantt_chart
Deletes a previously created Gantt chart.
| Parameter | Type | Required | Description |
|---|---|---|---|
| chart_id | string | Yes | The chart ID returned when the chart was created. |
| passcode | string | Yes | The passcode returned when the chart was created. |
Returns: Confirmation that the chart was removed.
Frequently Asked Questions
What is the Instagantt MCP server?
It's a remote Model Context Protocol (MCP) server at https://ai.instagantt.com/mcp that lets AI agents like Claude, ChatGPT, and Gemini create and manage professional Gantt charts programmatically — no browser automation or scraping needed.
Do I need an Instagantt account or API key?
No. Agents can create Gantt charts without an account and no API key is required. You only need an Instagantt account if you want to import the generated chart into your workspace to keep editing it.
What tools does the MCP server expose?
Two tools: create_gantt_chart, which generates a chart from a title and sections of tasks with dates, finish-to-start dependencies, and assignees, returning a public URL, an SVG image, and a JSON export; and delete_gantt_chart, which removes a chart using its ID and passcode.
Which AI assistants and agents work with it?
Any MCP-compatible client: Claude and Claude Code, ChatGPT, Cursor, Gemini-based agents, and open-source agent frameworks that speak the Model Context Protocol.
How do I add Instagantt to Claude Code?
Run a single command in your terminal: claude mcp add --transport http instagantt https://ai.instagantt.com/mcp — then verify with claude mcp list (you should see “✔ Connected”). No API key or sign-in is needed. Type /mcp inside Claude Code to see the server and its tools.
How do I add Instagantt to Claude Desktop?
Open Claude Desktop → Settings → Connectors → “Add custom connector”, name it Instagantt, and paste the remote MCP server URL https://ai.instagantt.com/mcp. Leave the OAuth fields blank — no authentication is required. Then enable Instagantt from the “+” menu in any chat.
What does create_gantt_chart return?
A public snapshot URL showing the interactive chart in a browser, an SVG image URL for embedding, a JSON URL with the full project data, and a chart ID and passcode the agent can use to delete or recreate the chart later.
Can I import an agent-created chart into Instagantt?
Yes. The public chart view includes a one-click import into your Instagantt account, where you can keep refining the plan with the full editor, collaborate with your team, and sync with Asana.
