Open-source ClickUp MCP alternatives
ClickUp's MCP server is closed and run by ClickUp. If you would rather use a server whose source you can read, audit, and fork, every option below publishes its code on a public host. That matters when you need to vet exactly what an agent can touch in a workspace, or when you want to pin a version and patch behaviour yourself instead of filing a ticket.
These are the open-source workspace servers people compare against ClickUp, ordered roughly by how widely they are used. Some install locally, a couple run as a hosted endpoint whose code is still public, and all of them let you inspect the source first.
The 8 best open-source alternatives
Notion's server is open source and reaches docs and databases, searching, reading, and writing across a workspace over OAuth. The closest all-in-one match to ClickUp, weighted toward pages, with code you can read.
Set up Notion →The chat slice of ClickUp, on its own: the community Slack server is open source and reads history, DMs, and search with no workspace bot. Its source is published, so you can confirm what it reaches.
Set up Slack →Open and tightly scoped to tasks, Doist's Todoist server creates, finds, updates, and completes tasks, projects, labels, and reminders. The task part of ClickUp without the docs and time tracking, with a repo you can read.
Set up Todoist →Schema-first structured data: the maintained Airtable server inspects a base, then reads, searches, and writes records, fields, and comments. It installs locally and its source is open, so you can audit it before granting write access.
Set up Airtable →Docs-as-data is Coda's shape, and the open-source server connects an agent to docs, pages, tables, and rows. It covers the document side of ClickUp from a local process whose code you can confirm.
Set up Coda →- TrelloCommunity
Board-style tracking fits Trello, and the open-source server covers boards, lists, cards, checklists, labels, members, and attachments. A simpler, inspectable kanban model where ClickUp's full workspace would feel heavy.
Set up Trello → Local Markdown kept on your own disk is Obsidian's point, and its open-source server reads, searches, and edits the vault through the Local REST API plugin. Reach for it when ClickUp's value to you was notes.
Set up Obsidian →Built on Telethon and fully open source, the Telegram server reads chats, manages groups and contacts, and sends or edits messages and media. The pick when the part of ClickUp you used was really team conversation.

How to choose
Among the open-source options, Notion stays closest to ClickUp's all-in-one workspace shape, with Coda and Airtable for structured docs and data. Todoist and Trello cover tasks and boards if you used a slice of ClickUp, while Slack and Telegram fit the chat, and Obsidian keeps notes on your own disk. Whichever you pick, read the repo before wiring it into a workspace with write access.
FAQ
- Is the ClickUp MCP server open source?
- No. ClickUp runs the server itself and does not publish its source, so you authenticate over OAuth and cannot audit or modify it. Every alternative on this page ships its code publicly on a code host.
- Do all of these open-source alternatives run on my own machine?
- Not all. Airtable, Coda, Trello, Obsidian, Slack, and Telegram install locally over stdio. Notion and Todoist publish their source but are operated as hosted endpoints over OAuth, so you can read the code even when you do not run the process.
