From Slack Threads to Specs: Custom MCP for Atlassian Workflows

When Slack conversations never make it to Confluence

Product discussions often happen where work is most active: Slack.
Ideas evolve through replies, someone points out an edge case, another person uploads a mockup.
At the end of the day, everything your team needs for a PRD already exists in the thread.

But the PRD itself does not.

Someone has to write it from scratch, gather context, copy content over, and organize it.
This becomes a recurring task for one unfortunate teammate.

Runbear and the official Atlassian MCP server remove this gap.
Your Slack thread becomes a structured Confluence PRD with a single request.

What this integration enables

After connecting the Atlassian MCP server to a Runbear Agent, you can capture any Slack conversation and generate a complete PRD inside Confluence.
The agent extracts the discussion, identifies key points, organizes them, and publishes a polished document.

It also supports creating related Jira tasks when needed.

This turns Slack into a starting point for documentation, not a dead end.

Setting it up

The workflow is straightforward. You only need one agent and one MCP connection.

1. Sign up for Runbear

Go to runbear.io and create an account.

2. Create your agent

Prepare the agent by defining:

• where PRDs are stored
• the sections you usually follow
• formatting or writing preferences

This gives the agent a consistent style to work with.

3. Connect the Atlassian MCP server using Custom MCP

In Integrations → Custom MCP, provide:

• Server name of your choice
• URL: https://mcp.atlassian.com/v1/sse
• Transport type: Server-Sent Events
• Authentication: OAuth

Once saved, call the agent in Slack.
A link will appear prompting you to approve access to your Atlassian site.

Using it in Slack

When you want to create a PRD, select a thread and ask the agent:

“Create a PRD from this conversation.”

The agent reads the messages, gathers context, and publishes a full document in Confluence.
If your team uses Jira, you can also request task creation in the same flow.

Why teams adopt this workflow

• Captures details directly from the real conversation
• Keeps Confluence and Jira continuously updated
• Reduces repetitive manual work
• Fits seamlessly into existing Slack-based workflows
• Helps teams move faster with less context loss

Slack becomes not only a communication tool but also a reliable entry point for documentation.
