Open-source Linear MCP alternatives
Linear's official server publishes its source, so you can already read how it creates, searches, and updates issues and projects. The reason to compare against the open-source servers below is usually that your team plans somewhere other than an issue tracker, and you want code you can audit before an agent gets write access to it.
Every option here ships its source publicly. You can read which API calls each makes, pin a version, and patch behaviour yourself rather than filing a ticket and waiting.
The 8 best open-source alternatives
Notion's open-source server searches, reads, and writes pages and databases. For doc-first planning rather than issues, the code is there to confirm what an agent can touch in a workspace.
Set up Notion →The community Slack server is open source and reads history, DMs, and search with no workspace bot install. Read the repo to see exactly which conversations an agent can reach.
Set up Slack →Open source and tightly scoped to tasks: create, find, update, and complete tasks, projects, labels, and reminders, with a repo from Doist you can read end to end.
Set up Todoist →Schema-first and fully open, the maintained Airtable server inspects a base, then reads, searches, and writes records, fields, and comments. Auditing it before granting writes is straightforward.
Set up Airtable →Coda's open-source server connects an agent to docs, pages, tables, and rows. The source confirms what it can edit, which matters for a doc tool an agent will modify.
Set up Coda →- TrelloCommunity
For board-style work, Trello's open-source server covers boards, lists, cards, checklists, labels, members, and attachments. A simple, inspectable model where a full tracker would be heavy.
Set up Trello → Local Markdown is the point of Obsidian, and its open-source server reads, searches, and edits the vault through the Local REST API plugin. You can see every call and keep files on your own disk.
Set up Obsidian →Built on Telethon and fully open source, the Telegram server reads chats, manages groups, and sends messages and media. Include it only if the planning around your work happened in a Telegram chat.

How to choose
All of these publish their code, including Linear itself, so the choice is about how you plan, not whether you can audit. Notion and Coda fit doc-first teams, Todoist and Trello fit task and board work, and Airtable fits relational records. Slack and Telegram cover the conversation side, while Obsidian keeps notes in local files. Read the repo before wiring any of them into work data with write access.
