Send GitHub Release Summaries to Slack

Use LangDB MCP to automatically extract and summarize GitHub release notes, then post clean updates into Slack channels.

Key Benefits

• Cut noise from raw GitHub feeds.

• Share structured highlights instantly.

• Keep project teams aligned without manual effort.

How It Works

GitHub Release Event ➔ LangDB Agent (Summarize) ➔ Post to Slack

The agent reads release notes, extracts key highlights, formats them for Slack, and posts into the specified channel.

Setup

Slack MCP Server

• Authentication: OAuth 2.0

• Environment Variables: None required

• OAuth authentication is triggered automatically when the MCP server is used.

Note: Ensure the Slack app has permission to post into the target Slack channels.

GitHub MCP Server

• Authentication: Personal Access Token (PAT)

• Environment Variables: Token needs to be manually set

• Recommended scopes for token:

  • repo (access to releases)

  • read:org (if monitoring org-related activities)

Checkout:

• Github MCP Server: https://app.langdb.ai/mcp-servers/github

• Slack MCP Server: https://app.staging.langdb.ai/mcp-servers/slack

Steps:

1. Generate a GitHub PAT from GitHub Developer Settings.

2. Configure the GitHub MCP server with this token.

Security Tip: Treat PATs as secrets—do not expose publicly.

MCP Server	Authentication Type
Slack	OAuth 2.0
GitHub	Personal Access Token

- Date: 2025-04-08
- Author: Karolis Gudiškis
