atlassian-browser-mcp

rowser-backed MCP wrapper for mcp-atlassian with Playwright SSO auth. Enables AI tools to access Atlassian Server/Data Center instances behind corporate SSO (Okta, SAML, ADFS) where API tokens are not available.

MCP server that wraps the upstream mcp-atlassian toolset with browser-cookie authentication via Playwright. Designed for Atlassian Server/Data Center instances behind corporate SSO (Okta, SAML, etc.) where API tokens are not available.

How it works

  1. On first use (or when the session expires), Playwright opens a real Chromium window for manual SSO/MFA
  2. After login, cookies are saved to a Playwright storage-state file
  3. All subsequent MCP tool calls use those cookies via a custom requests.Session subclass
  4. If an API response looks like an SSO redirect, the browser reopens automatically

The server monkey-patches JiraClient and ConfluenceClient constructors in mcp-atlassian to inject the browser-backed session, giving full parity with the upstream tool surface (72 tools + 1 atlassian_login helper = 73 total).

Files

FilePurpose
atlassian_browser_mcp_full.pyEntrypoint. Patches upstream clients, registers atlassian_login tool, runs the MCP server
atlassian_browser_auth.pyShared auth: BrowserCookieSession, interactive_login(), SSO detection
run-atlassian-browser-mcp.shLauncher: creates venv, installs deps via uv, runs compatibility check, starts server
pyproject.tomlDependency pins

Usage

./run-atlassian-browser-mcp.sh

Or configure as an MCP server in your editor (Cursor, Claude Code, etc.) pointing to the launcher script.
