What the Slack integration adds

Slack contains fast-moving decisions and troubleshooting details that may never become formal documentation. Unblocked makes authorized conversations researchable alongside code and tickets, so an agent can find the discussion that resolved an ambiguity and cite it back to the team.

It also brings Unblocked into Slack: your team can @mention the bot to ask questions, get auto-responses when Unblocked has a confident answer, or DM it privately. Answers reconcile Slack discussion with your code, pull requests, and docs.

Once connected, the same context is available to any MCP-compatible coding agent — Claude Code, Cursor, Windsurf, GitHub Copilot, Codex — through a single Unblocked MCP server connection.

What you get

• Channel history as context — Unblocked indexes the public and private channels you authorize and cites the thread it used, so decisions made in chat show up in answers.
• Ask Unblocked in Slack — Your team can @mention the bot, DM it, or get auto-responses when Unblocked has a confident answer — no context-switch out of Slack.
• Permission-aware private channels — Private channel support (paid) respects membership, with an approval step before private context is shared to a public channel.
• Cross-source synthesis — Slack threads are combined with your code, pull requests, Jira tickets, and docs into a single knowledge graph.

How to connect Slack to Unblocked

Need screenshots or troubleshooting? This is a concise connection summary.

Prerequisites

• An Unblocked account (free to start).
• A Slack Workspace Admin to connect Unblocked to your workspace. Private channel support requires a paid plan.
• An MCP-compatible coding agent (Claude Code, Cursor, Windsurf, etc.) to use the context in your editor.

Step 1: Connect Slack to Unblocked

1. In Unblocked, go to Settings → Data Sources → Connect another data source, and under Messaging platforms select Slack.
2. Sign in to Slack as a Workspace Admin and click Allow to grant access.
3. Select the channels to connect (public or private) and click Save Settings.
4. Invite Unblocked to the selected channels (Add and Continue); verify with "Is Unblocked listening?" in a channel.

Step 2: Install the Unblocked MCP server

On macOS or Linux, one command auto-detects and configures your supported agents (Claude Code, Cursor, Windsurf, GitHub Copilot, Codex, OpenCode, VS Code):

curl -fsSL https://getunblocked.com/install-mcp.sh | bash

On Windows, or when you prefer remote MCP, add the server manually using the configuration below, or follow the manual install guide.

Claude Code

Add the remote server, then run /mcp in Claude Code, select unblocked, and log in via OAuth:

claude mcp add -s user --transport http unblocked https://getunblocked.com/api/mcpsse

Cursor

Open View: Open MCP Settings → Add Custom MCP, add the server, then click Connect to authenticate via OAuth:

{
  "mcpServers": {
    "unblocked": {
      "url": "https://getunblocked.com/api/mcpsse"
    }
  }
}

Other MCP clients

Any MCP-compatible client (Windsurf, Codex, VS Code, Claude Desktop, and others) can connect to the remote server with OAuth:

https://getunblocked.com/api/mcpsse

Connect Slack to Claude Code, Cursor, and other AI agents

To give Claude Code, Cursor, GitHub Copilot, Codex, or another MCP-compatible AI coding agent access to Slack context, connect Slack to Unblocked and add the single Unblocked MCP server to your agent.

Unblocked acts as the MCP context layer for your Slack data, searching channels, threads, @mention Q&A alongside your other connected sources and returning cited results through these tools:

• context_research Multi-source research across your connected Slack channels and threads, plus your code, pull requests, and other connected sources. Returns a synthesized answer with citations back to the Slack message it used.
• context_get_urls Fetches the full content behind a Slack message URL your agent encounters — plus GitHub, Jira, Linear, Confluence, Notion, and more.

Questions to ask an AI agent about Slack

Questions you (or your agent) can ask Unblocked about your Slack data:

• What did the team decide about the rate-limit change in #engineering?
• Who discussed the flaky deploy last week, and what was the resolution?
• What was the context behind reverting the caching PR?
• Where did we land on the API versioning debate?
