Setup

Accept the invite

The data lives in one private GitHub repo: github.com/MicahFalde/contextwindow. You get an invite as a collaborator. Accept it before anything else; every step below reads that repo as you.

Install

One command in a terminal. The -s user part registers it once for every project on your machine:

claude mcp add -s user contextwindow -- npx -y github:MicahFalde/contextwindow-mcp

It needs Node 20 or newer on your machine and a GitHub login for the same account the invite went to. Either sign in with gh auth login or set GITHUB_TOKEN in your environment.

Use it

Then just talk to it. Three things worth saying:

• add an agenda item: what I learned running agents against prod
• what is everyone working on
• share my project "Context Window MCP" and attach these files

Two slash commands are there when you want a fixed starting point:

• /mcp__contextwindow__prep reads your last week of commits, asks what else you did, drafts your three-sentence roundtable item, and posts it only when you say so.
• /mcp__contextwindow__brief pulls the agenda and everyone's project updates into one screen before the call.

Sharing code

Files go up only when you ask for them; a summary saves without any. The limits: 25 files, 250 KB each, 2 MB in total. Past that, give the repo_url instead and the reader can follow it.

Credentials are caught on your own machine before a single byte is sent. The scan rejects the whole write when it sees a token, so keep the blocks short and numbered. Share only what is yours to share.

The room

The full view is at /room/, behind a plain GitHub login. It remembers you for a week. To get out: /auth/logout.

Without Claude Code

The room page carries everything, and you can edit the files themselves on github.com. One file per item, in the folders agenda/<date>/, projects/<login>/ and recaps/. Plain markdown; a blank line between frontmatter and body, two dashes on their own lines around the frontmatter. A push regenerates both views within a minute.
