jira-issue-context-mcp

Read-only MCP server that gives Codex, Claude, Cursor, or any MCP client the context for a specific Jira issue.

It intentionally does one thing: fetch a single issue by key and return the issue title, description, comments, attachment summary, and image attachments.

Features

• Single read-only tool: jira_issue_context

• No board listing, sprint browsing, JQL search, transitions, comments, or writes

• Converts Jira ADF descriptions/comments into plain Markdown-ish text

• Paginates all issue comments

• Returns image attachments as MCP image content

• Supports Atlassian Cloud API token auth, bearer auth, or browser/session cookie auth

• Optional Playwright login helper for cookie-based SSO setups

Install

Authentication

Set JIRA_BASE_URL plus one auth method.

You can put these variables in the shell environment or in a .env file in the directory where the MCP command is started. The package also checks its own local .env as a fallback.

Recommended for Atlassian Cloud:

JIRA_BASE_URL=https://your-domain.atlassian.net
JIRA_EMAIL=you@example.com
JIRA_API_TOKEN=your-atlassian-api-token

Bearer token:

JIRA_BASE_URL=https://your-domain.atlassian.net
JIRA_BEARER_TOKEN=your-token

Cookie/session token:

JIRA_BASE_URL=https://your-domain.atlassian.net
JIRA_SESSION_TOKEN=your-cookie-value
JIRA_COOKIE_NAME=tenant.session.token

For SSO environments where API tokens are not available, the login helper can capture a browser cookie:

npx -y --package github:formonkey/jira-issue-context-mcp#main jira-issue-login \
  --base-url=https://your-domain.atlassian.net \
  --cookie-name=tenant.session.token \
  --browser-channel=msedge

Run it from your project root. The login helper writes JIRA_SESSION_TOKEN to .env in the current directory and uses a persistent Playwright profile at .auth/browser-profile by default. --browser-channel=msedge uses your installed Edge instead of downloading Playwright's Chromium. You may need to complete SSO/MFA manually the first time; later runs reuse the browser session while it remains valid.

If Microsoft SSO blocks the automated browser, start Edge yourself with remote debugging and let the helper connect to that real Edge session:

npx -y --package github:formonkey/jira-issue-context-mcp#main jira-issue-login \
  --base-url=https://your-domain.atlassian.net \
  --cookie-name=tenant.session.token \
  --launch-browser=msedge \
  --cdp-port=9222 \
  --default-profile=true \
  --close-existing-browser=true

This closes existing Edge processes, launches a real Edge process with the installed browser's default profile, connects to it over CDP, waits for you to finish Microsoft SSO, captures the Jira session cookie, and writes it to .env.

Advanced manual mode:

start msedge --remote-debugging-port=9222

Then run:

npx -y --package github:formonkey/jira-issue-context-mcp#main jira-issue-login \
  --base-url=https://your-domain.atlassian.net \
  --cookie-name=tenant.session.token \
  --cdp-url=http://127.0.0.1:9222

Both CDP modes are useful for corporate SSO because the browser is launched as a normal installed browser instead of a Playwright-managed browser.

Codex Project Config

Example .codex/config.toml:

[mcp_servers.jira_issue]
command = "node"
args = ["/absolute/path/to/jira-issue-context-mcp/dist/index.js"]
cwd = "/absolute/path/to/jira-issue-context-mcp"
env_vars = [
  "JIRA_BASE_URL",
  "JIRA_EMAIL",
  "JIRA_API_TOKEN",
  "JIRA_BEARER_TOKEN",
  "JIRA_SESSION_TOKEN",
  "JIRA_COOKIE_NAME",
  "JIRA_MAX_IMAGE_MB"
]
enabled = true
startup_timeout_sec = 20
tool_timeout_sec = 90
default_tools_approval_mode = "auto"

Then ask your agent:

JIRA CORE-7584: read the issue context and prepare an implementation plan.

The agent should call:

{ "issueKey": "CORE-7584" }

Tool

jira_issue_context

Parameters:

• issueKey required in normal chat-driven usage, e.g. CORE-7584

• includeComments optional, defaults to true

• includeImages optional, defaults to true

• maxImageSizeMB optional, defaults to JIRA_MAX_IMAGE_MB or 8

The server also supports --issue=KEY or JIRA_ISSUE_KEY as fallback defaults, but passing the issue key from chat is usually cleaner.
