jira-dev-mcp

A local MCP server for Jira Cloud-driven development. Connects Claude Code, OpenCode, Codex, and other MCP clients to your Jira instance — search issues, read task details, parse attachments, and map Jira projects to local repositories.

Other languages: 中文 · 日本語

Features

• Search Jira issues with natural language or raw JQL

• Read full task details: description, subtasks, changelog, comments, attachments

• Download and parse CSV, XLSX, XLS, PDF attachments via Python

• Images and binary files passed to AI client as base64

• Map Jira project keys to local repository paths

• OAuth 2.0 (3LO) browser-based login — no manual token management

• Auto-refresh OAuth tokens before expiry

• Post comments on Jira issues with clickable URL response

• Token-only comment confirmation: confirm pending comments with just the token, no need to re-send body

• Edit existing comments with the same confirmation flow

• Batch download all attachments from an issue in a single call with optional MIME filter

• Auto-retry on transient API errors (429/503) with Retry-After header support

• Rich ADF parsing: code blocks, tables, mentions, links, panels, and more

• Multi-paragraph and fenced code block support in posted comments

• Typed error hierarchy for programmatic error handling

• OAuth callback port auto-fallback when default port is busy

• Read and write Jira access

Install

npm install -g jira-dev-mcp

Authentication

Option A: OAuth 2.0 (Recommended)

Just run:

jira-dev login

A browser window opens for Jira authorization. Tokens are saved to ~/.jira-dev/config.json and auto-refreshed. No manual Client ID or Secret required.

Advanced: To use your own OAuth app, set JIRA_CLIENT_ID and JIRA_CLIENT_SECRET before running jira-dev login.

Option B: API Token (Basic Auth)

export JIRA_BASE_URL="https://your-domain.atlassian.net"
export JIRA_EMAIL="you@example.com"
export JIRA_TOKEN="your-jira-api-token"

Optional — store token in macOS Keychain instead of env var:

security add-generic-password -a "$USER" -s "jira-dev-mcp:JIRA_TOKEN" -w "your-token"

MCP Client Configuration

Auto-register (easiest)

jira-dev setup

This creates or updates ~/.claude.json (Claude Code) and ~/.opencode/config.json (OpenCode) automatically. If an existing config file contains invalid JSON, jira-dev setup now fails with an explicit error instead of silently skipping it.

Manual — Claude Code (~/.claude.json)

{
  "mcpServers": {
    "jira": {
      "command": "jira-dev",
      "args": ["server"]
    }
  }
}

Manual — OpenCode / Codex

{
  "mcpServers": {
    "jira": {
      "command": "jira-dev",
      "args": ["server"]
    }
  }
}

With environment variables

{
  "mcpServers": {
    "jira": {
      "command": "jira-mcp-server",
      "env": {
        "JIRA_BASE_URL": "https://your-domain.atlassian.net",
        "JIRA_EMAIL": "you@example.com",
        "JIRA_TOKEN": "your-token"
      }
    }
  }
}

Tools

CLI Commands

jira-dev status    # Show current auth mode, token state, and mapped projects
jira-dev doctor    # Run environment and config health checks
jira-dev upgrade   # Upgrade jira-dev-mcp from npm
jira-dev setup     # Register jira-dev into supported MCP clients
jira-dev read AT-123             # Read issue details from the terminal
jira-dev comment AT-123 "Done"   # Post a comment directly (bypasses manual mode)
jira-dev download AT-123         # Download all attachments
jira-dev download AT-123 spec.xlsx  # Download a single attachment

Development Workflow

Standard usage with Claude Code

Step 1 — One-time setup: map your project

jira_set_project_path(jiraProject: "AT", localPath: "/path/to/your/repo")

Step 2 — Find your task

jira_my_tasks(status: "In Progress")

or search by keyword / JQL:

jira_search_issues(query: "login timeout bug")
jira_search_issues(query: "project = AT AND sprint in openSprints()")

Step 3 — Read the task

jira_read_task(key: "AT-123", includeComments: true)

Returns: description, subtasks, changelog, comments, attachment list, and the local repo path.

Step 4 — Download attachments if needed

jira_download_all_attachments(key: "AT-123")
jira_download_all_attachments(key: "AT-123", mime_filter: "image/")
jira_download_attachment(key: "AT-123", filename: "spec.xlsx")

Use jira_download_all_attachments to grab everything in one call, or filter by MIME type. Use jira_download_attachment for a single file. CSV / XLSX / XLS / PDF are parsed and returned as structured text. Images are returned as base64.

Step 5 — AI implements the fix

With the task details and local repo path in context, ask Claude Code to:

• Explain the root cause

• Propose a plan with impact scope

• Implement the fix

• Write test cases

Project Path Mapping

Map a Jira project key to a local repo so the AI knows where to look:

jira_set_project_path(jiraProject: "AT", localPath: "/Users/you/projects/my-app")

Python Dependency (Attachment Parsing)

Python 3 is required for CSV, XLSX, XLS, and PDF parsing. For XLS and PDF, additional packages are auto-installed on first use, or install manually:

python3 -m pip install -r $(npm root -g)/jira-dev-mcp/scripts/requirements.txt

Security

• OAuth tokens stored at ~/.jira-dev/config.json with 600 permissions

• API tokens: prefer env vars or macOS Keychain over config file

• Attachment size and MIME type allowlist enforced before download

• OAuth client credentials injected at build time — never committed to source

• Secrets are never written to logs

Local Development

git clone https://github.com/nianyi778/jira-dev-mcp.git
cd jira-dev-mcp
npm install
npm run generate-defaults   # required before first build (uses env vars or empty placeholders)
npm test
npm run build
