Refresh expired Slack browser tokens (xoxc/xoxd) using persistent browser sessions. Use when Slack MCP tools fail with authentication errors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Slack Token Extractor Refresh expired Slack browser session tokens (`xoxc`/`xoxd`) used by Slack MCP server. ## System requirements Need system Chrome/Chromium binary — `CHROME_PATH` must set in `.env` (e.g. `CHROME_PATH=/usr/bin/google-chrome-stable`). Playwright bundled Chromium never used — services fingerprint as bot traffic. On **headless servers**, `setup_slack_session` also need VNC stack for interactive login: ```bash apt install xvfb x11vnc novnc ``` Plugin check missing deps at startup, log warnings. ## How it works Use Playwright persistent browser contexts — after one manual login (human handle CAPTCHA/magic-link), later token extractions run headless using saved session. ## First-time setup (requires human) Before tokens auto-refresh, human must log in once: ``` setup_slack_session(workspace_name="acme") ``` Open **visible** Chromium window. Human complete Slack login flow (CAPTCHA, magic link, SSO — whatever Slack require). Session saved for future headless use. …

How to install
mdr add crypdick/pynchy/slack-token-extractor@sha256:c206715f81d7a766The line at the top of this page pins the label git:20260727.2785f4d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
