Jira MCP Server

A Model Context Protocol (MCP) server for Jira API integration. This server enables AI assistants like Claude to interact with Jira Cloud instances for issue management, search, comments, workflow transitions, and attachment handling.

Features

• Issue Management: Get, create, update, and assign Jira issues with custom field support
• JQL Search: Search issues using Jira Query Language
• Comments: Add and retrieve comments on issues
• Workflow: Get available transitions and change issue status
• Metadata Discovery: Get field requirements and allowed values for projects
• User Search: Find users by email or name for assignments
• Projects: List all accessible projects
• Attachments: List, upload, delete attachments and retrieve their content — text files returned as text, images rendered inline via Claude vision
• Token Efficient: 5 compound tools instead of 16 flat tools — ~50% fewer tokens per session

Tool Architecture

This server exposes 5 compound tools — each with an action parameter that selects the operation. This design reduces the token overhead of tool definitions by ~50% compared to 16 flat tools, leaving more context for actual work.

Tool	Actions	Description
jira_issues	get create update assign	Full issue lifecycle management
jira_search	issues projects users create_metadata	Search and discovery
jira_comments	get add	Read and write comments
jira_workflow	get_transitions transition	Status transitions
jira_attachments	list get_content upload delete	File attachments

---

Available Tools

jira_issues

Manage the full lifecycle of Jira issues.

Required: action

Action	Description	Required params	Optional params
get	Fetch full issue details	issueKey	—
create	Create a new issue	projectKey, summary, issueType	description, priority, assignee, labels, customFields
update	Edit fields on an existing issue	issueKey	summary, description, priority, assignee, labels, customFields
assign	Set or clear the assignee	issueKey, assignee	—

Tips:

• Always call jira_search with action=create_metadata before creating issues to discover required custom fields and allowed values.
• Pass assignee: "-1" to unassign an issue.
• description accepts plain text or an Atlassian Document Format (ADF) object.
• customFields is a key-value map: {"customfield_10000": "value"}.

Examples:

Get details for PROJ-123
Create a Bug in project PROJ with summary "Login button broken"
Update PROJ-123 priority to High
Assign PROJ-123 to john.doe@company.com

---

jira_search

Search and discover Jira resources.

Required: action

Action	Description	Required params	Optional params
issues	Search issues via JQL	jql	maxResults
projects	List all accessible projects	—	maxResults
users	Find users by name or email	query	maxResults
create_metadata	Get field requirements for creating issues	projectKey	issueType

Common JQL examples:

project = PROJ AND status = Open
assignee = currentUser() AND status != Done
priority = High AND created >= -7d

Tips:

• Use create_metadata before jira_issues create to understand what fields are required for a project/issue type.
• Use users to look up account IDs for assignments — pass the returned account ID or email to jira_issues assign.

---

jira_comments

Read and write comments on a Jira issue.

Required: action, issueKey

Action	Description	Required params
get	Fetch all comments on an issue	—
add	Post a new comment	comment

comment accepts plain text or an ADF object.

Examples:

Get all comments on PROJ-123
Add a comment to PROJ-123: "Fixed in PR #456"

---

jira_workflow

Manage issue status transitions.

Required: action, issueKey

Action	Description	Required params	Optional params
get_transitions	List available status transitions	—	—
transition	Move issue to a new status	transitionId	comment

Tip: Always call get_transitions first — transition IDs vary per project and issue type. The transitionId from the response is what you pass to transition.

Examples:

Get available transitions for PROJ-123
Move PROJ-123 to "In Progress" (use get_transitions first to find the ID)

---

jira_attachments

Manage file attachments on Jira issues.

Required: action

Action	Description	Required params	Optional params
list	List all attachments with metadata	issueKey	—
get_content	Download and return file content	attachmentId	mimeType
upload	Attach a local file to an issue	issueKey, filePath	fileName
delete	Remove an attachment by ID	attachmentId	—

Content types returned by get_content:

• Text files (text/*, application/json, application/xml): returned as readable text
• Images (image/*): returned as base64 — Claude will render them inline
• Other types (PDF, zip, etc.): returns file metadata with a descriptive message

Tips:

• Use list first to get attachment IDs before calling get_content or delete.
• fileName in upload overrides the filename shown in Jira (defaults to the file's basename).

Examples:

List attachments on PROJ-123
Get the content of attachment 136904
Upload /tmp/report.pdf to PROJ-123
Delete attachment 136904

API Reference

This server uses the Jira REST API v3.

Troubleshooting

"Error: JIRA_EMAIL and JIRA_API_TOKEN are required"

Make sure you've set the environment variables in your MCP configuration.

Authentication errors

• Verify your API token is correct
• Ensure your email matches your Atlassian account
• Check that your JIRA_BASE_URL doesn't have a trailing slash

Permission errors

The API token uses the permissions of the user who created it. Make sure your account has the necessary permissions for the actions you're trying to perform.
