Full read-write Claude connector for Basecamp
Make Claude create and assign to-dos and post updates in Basecamp
Stop clicking through each Basecamp project to keep work moving. Claude creates to-dos in the right list, sets assignees and due dates, posts message board updates, and checks items off as work completes, all where the project already lives.
Basecamp is a project management and team collaboration tool where work lives in projects with to-do lists, message boards, schedules, and group chat. People want Claude to do more than read updates: to create and assign to-dos, post messages, and keep projects moving on their behalf.
What is a Basecamp MCP server?
A Basecamp MCP server is a small hosted service that exposes Basecamp's data and actions to Claude over the Model Context Protocol, so Claude can tasks, projects, and docs inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can Basecamp's current connector do today?
Today, any available Basecamp connection for Claude tends to be read-leaning or a thin slice: Claude can look up projects, to-dos, and messages, but creating to-dos, assigning them, posting to a message board, and commenting are often limited or unavailable. A custom Basecamp connector adds those write actions with scoped, human-in-the-loop controls.
What does full read-write Basecamp access unlock?
Full read-write Basecamp access lets Claude create to-dos in the right list, set assignees and due dates, post to a message board, add comments, and check items off as work completes. The project upkeep that used to mean clicking through each tool happens where the work already lives, once you approve.
- Create a to-do in a chosen list with an assignee, due date, and notes
- Post a message to a project's message board to share an update
- Add a comment to a to-do or message to capture context
- Mark to-dos complete or reopen them as work progresses
- Set or change the assignee and due date on existing to-dos
- Create a new to-do list to break a project into tracked groups
Can Claude create and assign to-dos in Basecamp?
Yes. With a full read-write Basecamp connector, Claude can create a to-do in the list you choose, set the assignee and due date, and add notes. It can also reopen or check off items as work progresses, so project upkeep happens without you clicking through each tool.
Can Claude post a message and add comments in Basecamp?
Claude can post a message to a project's message board to share an update, and add comments to to-dos or messages to capture context. It works inside the projects you already have access to, so updates land in the right place rather than in a separate note.
Will Claude delete or archive Basecamp items on its own?
Will Claude delete or archive items on its own: no. Destructive actions like deleting a to-do or trashing a project are gated and wait for your confirmation. Routine writes such as creating a to-do or posting a comment flow freely, and the connector never gets more access than your own account has.
How a Basecamp connector works
We build a small MCP server that authenticates to Basecamp with OAuth and the narrowest scopes the work needs. Read tools (search, look up projects, to-dos, and messages) and write tools (create, assign, comment, post) are separated, and destructive actions like deleting an item require your confirmation. Claude only ever has the access your own Basecamp account already has.
