Making a Gantt chart with Claude

Can you make a Gantt chart with Claude? Yes. Connect Claude to PalmaPlan, a scheduling tool that is also an MCP server, and describe your project: Claude builds the schedule — phases, rows, dated blocks, dependencies, milestones —, you watch it fill in live, and the Gantt chart opens in the conversation, where it can be edited.

In short

• One command for Claude Code: claude mcp add --transport http palmaplan https://palmaplan.com/mcp.
• Your consent in the browser: Claude receives a token in its own name, which you can see and revoke.
• One sentence for the schedule: "Build me the redesign schedule: scoping in October, six weeks of development, acceptance testing before Christmas."
• A real Gantt chart, not a picture: you can also drive it with the mouse, share it, export it.
• By invitation during the beta; the data is hosted in France.

Step by step

1. An account on palmaplan.com. Access is by invitation during the beta — request yours.
2. Connect Claude. In Claude Code, the command above. In Claude, a custom connector to https://palmaplan.com/mcp. No package to install, no key to paste: Claude registers itself with PalmaPlan.
3. Give your consent. Your browser opens on a page that names the client and what it asks for (read, write, or both). You accept or refuse; if you accept, Claude leaves with a named token, valid for thirty days, visible in Settings › Connections and agents › Connected applications.
4. Describe the project. In plain language, with your dates, your phases, your constraints. Claude builds the whole schedule; your screen, if it is open, watches it fill in without reloading.
5. Look and correct. In Claude, the Gantt chart appears in the conversation (an MCP App): move a block, change a date, by hand or by asking. Elsewhere, Claude gives you the schedule's link.

What Claude can do next

• Answer about the schedule: what is late, the critical path, what changed since Monday.
• Try without breaking: "What if acceptance testing slipped two weeks?" — the answer comes without a single date moving; you apply it afterwards, or not.
• Track progress: split a block into actions, assign them to a person or to an AI, tick them off — the block's progress computes itself.
• Get the schedule out: in the v23 exchange format, as CSV, a spreadsheet, an image or a PDF.

What stays yours

Everything Claude writes is signed in its name in the schedule's History. Ctrl+Z stays yours. It acts with your rights, never more: a reader only gives it a reader. And it does not touch your account — no password, no profile, no export, no deletion: those gestures stay yours.

What has not been tried yet

The view in the conversation was played in Claude, the desktop app, through a connector to https://palmaplan.com/mcp. Not tried yet: claude.ai in the browser, the mobile app, the kanban and the agenda in the conversation. The embedded view guide keeps this list up to date.

Going further

• Connecting Claude Code — the authorisation step by step, and what to check when it gets stuck.
• The embedded view — the Gantt chart in the conversation, its options.
• A schedule an AI can edit — the safeguards, in detail.
• Project management and MCP — why an open protocol rather than an integration.
• The website's MCP page — the command, and what an agent can do.
