What's Wrong?
Description
When using Claude Code via Slack, the GitHub connector is not accessible, while other MCP connectors (Sentry, Cloudflare) work perfectly. The same GitHub connector works correctly on Claude Code Web (claude.ai/code).
Environment
- Claude Plan: Max
- Platform: Slack (Claude App)
- GitHub App: Installed with "All repositories" access + Read/Write permissions
Current Behavior
When asking Claude in Slack about available integrations:
| Service | Access via Web (claude.ai/code) | Access via Slack |
|---------|--------------------------------|------------------|
| GitHub | ✅ Works | ❌ Not accessible |
| Sentry (MCP) | ✅ Works | ✅ Works |
| Cloudflare (MCP) | ✅ Works | ✅ Works |
What Should Happen?
GitHub should be accessible from Slack, just like it is on Claude Code Web, since:
- GitHub connector shows as "Connected" in claude.ai settings
- GitHub App is installed with full permissions (All repositories, Read/Write)
- Slack is properly connected to Claude account
- Routing Mode is set to "Code only"
Error Messages/Logs
Claude in Slack responds:
> "Je n'ai pas accès à GitHub. Si vous souhaitez que j'aie accès à vos repos GitHub, il faudrait que cette intégration soit ajoutée via les connecteurs MCP (Model Context Protocol)."
## Configuration
### GitHub App permissions (on GitHub)
- ✅ Read access to actions, checks, and metadata
- ✅ Read and write access to code, discussions, issues, pull requests, and workflows
- ✅ Repository access: All repositories
### Claude Connectors (on claude.ai)
- ✅ GitHub: Connected
- ✅ Cloudflare Developer Platform: Configured
- ✅ Sentry: Configured
### Slack App Home
- ✅ Connected to Claude (correct account)
- ✅ Routing Mode: Code only
- ✅ Model: OpusSteps to Reproduce
- Install Claude App in Slack workspace
- Connect Claude account in App Home
- Have GitHub connector connected on claude.ai
- Have MCP connectors (Sentry, Cloudflare) configured
- Ask Claude in Slack: "Do you have access to GitHub?"
- Claude responds that GitHub is not accessible, while confirming Sentry and Cloudflare work

Additional Information
The issue seems to be that GitHub is a "native connector" while Sentry/Cloudflare are MCP connectors. MCP connectors are properly propagated to Slack, but the native GitHub connector is not.
This is blocking the main use case of Claude Code in Slack: working on code repositories.

The same issue for me as well. Claude app on Slack can't see the Github connector. Even though it shows as connected. And Claude Code for Web sees my repos
I think I found an issue - it doesn't work in chat with Claude app, but works perfectly fine if Claude is mentioned in the Slack channel.
Anthropic should have fixed this issue as I just disconnected/reconnected my claude account from Slack and it now works.
@iamgalba do you want me to close this issue or do you want me to keep it opened ?
