Setup Wizard

npx @jtalk22/slack-mcp --setup

macOS: Tokens extracted from Chrome via AppleScript.
Linux/Windows: Guided entry with API validation before save.

Session Mirroring

Slack official API path: create app, request scopes, wait for admin approval. DM access requires per-conversation consent—even for your own messages.

Session mirroring works differently. It uses your browser credentials (xoxc- token + xoxd- cookie) to mirror your logged-in session. Same access you have in-browser, now queryable. Your Slack, extended to your workflow.

No app registration. No approval chain. Just your existing access, working where you need it.

Node 20+ Required

Node 18 EOL was October 2025. This release enforces engines: >=20.0.0.

Technical Details

Setup Wizard

• Platform detection: darwin → AppleScript extraction, else manual flow
• Token validation: auth.test call before persisting
• Storage: ~/.slack-mcp-tokens.json with chmod 600

Stability

• Atomic writes (temp-file-then-rename)
• Mutex lock on Chrome extraction
• LRU user cache (500 users, 1-hour TTL)
• Exponential backoff with jitter
