GanttFather MCP server
A remote Model Context Protocol server for GanttFather, an online Gantt chart and Kanban tool. It lets an AI assistant read and edit your GanttFather projects: tasks, dates, dependencies, resources, the critical path, and the chart itself.
This repository holds documentation and the registry entry only. The server is hosted; there is nothing to install or run.
- URL:
https://mcp.ganttfather.com/ - Transport: streamable HTTP
- Sign-in: OAuth 2.1 with dynamic client registration and PKCE (S256), scopes
mcp:readandmcp:write. Clients that can't do OAuth can send a project token from GanttFather (AI Agents & API) asAuthorization: Bearer <token>. - Official MCP Registry:
com.ganttfather/ganttfather - Docs and setup guides: https://ganttfather.com/mcp/
- Price: free for one project with two editors; viewers and guests are free.
Add it to your client
The quickest way is to add the URL as a remote server and sign in when your client asks.
Claude (claude.ai and the desktop app): Settings, Connectors, Add custom connector, then paste https://mcp.ganttfather.com/.
Claude Code
claude mcp add --transport http ganttfather https://mcp.ganttfather.com/VS Code (GitHub Copilot Chat), in .vscode/mcp.json:
{ "servers": { "ganttfather": { "type": "http", "url": "https://mcp.ganttfather.com/" } } }GitHub Copilot CLI
copilot mcp add --transport http ganttfather https://mcp.ganttfather.com/Then run /mcp auth ganttfather inside Copilot CLI.
Cursor, in ~/.cursor/mcp.json:
{ "mcpServers": { "ganttfather": { "url": "https://mcp.ganttfather.com/" } } }Windsurf and Antigravity, in mcp_config.json (they read serverUrl):
{ "mcpServers": { "ganttfather": { "serverUrl": "https://mcp.ganttfather.com/" } } }Codex
codex mcp add ganttfather --url https://mcp.ganttfather.com/Gemini CLI, in settings.json (it needs httpUrl; a plain url means an older transport there):
{ "mcpServers": { "ganttfather": { "httpUrl": "https://mcp.ganttfather.com/" } } }OpenCode, in opencode.json, then run opencode mcp auth ganttfather:
{ "$schema": "https://opencode.ai/config.json", "mcp": { "ganttfather": { "type": "remote", "url": "https://mcp.ganttfather.com/", "enabled": true } } }Guides for ChatGPT, Gemini, Goose, n8n and others are at https://ganttfather.com/mcp/. Of the clients above, we have tested Claude end to end; reports from the others are welcome in Issues.
Tools
27 tools. Every tool sets readOnlyHint, destructiveHint and openWorldHint explicitly; writes that can overwrite or remove data are marked destructive, so your client can ask before running them.
