Quick Start

Get up and running in 2 minutes:

1. Get Your Jira Credentials

Generate a Jira API Token:

1. Go to Atlassian API Tokens
2. Click Create API token
3. Give it a name like "AI Assistant"
4. Copy the generated token immediately (you won't see it again!)

2. Try It Instantly

# Set your credentials
export ATLASSIAN_SITE_NAME="your-company"  # for your-company.atlassian.net
export ATLASSIAN_USER_EMAIL="your.email@company.com"
export ATLASSIAN_API_TOKEN="your_api_token"

# List your Jira projects
npx -y @aashari/mcp-server-atlassian-jira get --path "/rest/api/3/project/search"

# Get details about a specific project
npx -y @aashari/mcp-server-atlassian-jira get --path "/rest/api/3/project/DEV"

# Get an issue with JMESPath filtering
npx -y @aashari/mcp-server-atlassian-jira get --path "/rest/api/3/issue/PROJ-123" --jq "{key: key, summary: fields.summary, status: fields.status.name}"

Connect to AI Assistants

For Claude Desktop Users

Add this to your Claude configuration file (~/.claude/claude_desktop_config.json):

{
  "mcpServers": {
    "jira": {
      "command": "npx",
      "args": ["-y", "@aashari/mcp-server-atlassian-jira"],
      "env": {
        "ATLASSIAN_SITE_NAME": "your-company",
        "ATLASSIAN_USER_EMAIL": "your.email@company.com",
        "ATLASSIAN_API_TOKEN": "your_api_token"
      }
    }
  }
}

Restart Claude Desktop, and you'll see the jira server in the status bar.

For Other AI Assistants

Most AI assistants support MCP. Install the server globally:

npm install -g @aashari/mcp-server-atlassian-jira

Then configure your AI assistant to use the MCP server with STDIO transport.

Alternative: Configuration File

Create ~/.mcp/configs.json for system-wide configuration:

{
  "jira": {
    "environments": {
      "ATLASSIAN_SITE_NAME": "your-company",
      "ATLASSIAN_USER_EMAIL": "your.email@company.com",
      "ATLASSIAN_API_TOKEN": "your_api_token"
    }
  }
}

Alternative config keys: The system also accepts "atlassian-jira", "@aashari/mcp-server-atlassian-jira", or "mcp-server-atlassian-jira" instead of "jira".

Available Tools

This MCP server provides 5 generic tools that can access any Jira API endpoint:

Common API Paths

Projects:

• /rest/api/3/project/search - List all projects (paginated, recommended)
• /rest/api/3/project - List all projects (non-paginated, legacy)
• /rest/api/3/project/{projectKeyOrId} - Get project details

Issues:

• /rest/api/3/search/jql - Search issues with JQL (use jql query param). IMPORTANT: /rest/api/3/search is deprecated!
• /rest/api/3/issue/{issueIdOrKey} - Get issue details
• /rest/api/3/issue - Create issue (POST)
• /rest/api/3/issue/{issueIdOrKey}/transitions - Get/perform transitions

Comments:

• /rest/api/3/issue/{issueIdOrKey}/comment - List/add comments
• /rest/api/3/issue/{issueIdOrKey}/comment/{commentId} - Get/update/delete comment

Worklogs:

• /rest/api/3/issue/{issueIdOrKey}/worklog - List/add worklogs
• /rest/api/3/issue/{issueIdOrKey}/worklog/{worklogId} - Get/update/delete worklog

Users & Statuses:

• /rest/api/3/myself - Get current user
• /rest/api/3/user/search - Search users (use query param)
• /rest/api/3/status - List all statuses
• /rest/api/3/issuetype - List issue types
• /rest/api/3/priority - List priorities

TOON Output Format

By default, all responses use TOON (Token-Oriented Object Notation) format, which reduces token usage by 30-60% compared to JSON. TOON uses tabular arrays and minimal syntax, making it ideal for AI consumption.

To use JSON instead: Add --output-format json to CLI commands or set outputFormat: "json" in MCP tool calls.

Example TOON vs JSON:

TOON: key|summary|status
      PROJ-1|First issue|Open
      PROJ-2|Second issue|Done

JSON: [{"key":"PROJ-1","summary":"First issue","status":"Open"},
       {"key":"PROJ-2","summary":"Second issue","status":"Done"}]

JMESPath Filtering

All tools support optional JMESPath (jq) filtering to extract specific data:

# Get just project names and keys
npx -y @aashari/mcp-server-atlassian-jira get \
  --path "/rest/api/3/project/search" \
  --jq "values[].{key: key, name: name}"

# Get issue key and summary
npx -y @aashari/mcp-server-atlassian-jira get \
  --path "/rest/api/3/issue/PROJ-123" \
  --jq "{key: key, summary: fields.summary, status: fields.status.name}"

Response Truncation and Raw Logs

For large API responses (>40k characters ≈ 10k tokens), responses are automatically truncated with guidance. The complete raw response is saved to /tmp/mcp/mcp-server-atlassian-jira/<timestamp>-<random>.txt for reference.

When truncated, you'll see:

• A truncation notice with the raw file path
• Suggestions to refine your query with better filters
• Percentage of data shown vs total size

Real-World Examples

Explore Your Projects

Ask your AI assistant:

• "List all projects I have access to"
• "Show me details about the DEV project"
• "What projects contain the word 'Platform'?"

Search and Track Issues

Ask your AI assistant:

• "Find all high priority issues in the DEV project"
• "Show me issues assigned to me that are in progress"
• "Search for bugs reported in the last week"
• "List all open issues for the mobile team"

Manage Issue Details

Ask your AI assistant:

• "Get full details about issue PROJ-456 including comments"
• "What's the current status and assignee of PROJ-123?"
• "Display all comments on the authentication bug"

Issue Communication

Ask your AI assistant:

• "Add a comment to PROJ-456: 'Code review completed, ready for testing'"
• "Comment on the login issue that it's been deployed to staging"

CLI Commands

The CLI mirrors the MCP tools for direct terminal access:

# GET request (returns TOON format by default)
npx -y @aashari/mcp-server-atlassian-jira get --path "/rest/api/3/project/search"

# GET with query parameters and JSON output
npx -y @aashari/mcp-server-atlassian-jira get \
  --path "/rest/api/3/search/jql" \
  --query-params '{"jql": "project=DEV AND status=\"In Progress\"", "maxResults": "10"}' \
  --output-format json

# GET with JMESPath filtering to extract specific fields
npx -y @aashari/mcp-server-atlassian-jira get \
  --path "/rest/api/3/issue/PROJ-123" \
  --jq "{key: key, summary: fields.summary, status: fields.status.name}"

# POST request (create an issue)
npx -y @aashari/mcp-server-atlassian-jira post \
  --path "/rest/api/3/issue" \
  --body '{"fields": {"project": {"key": "DEV"}, "summary": "New issue title", "issuetype": {"name": "Task"}}}'

# POST request (add a comment)
npx -y @aashari/mcp-server-atlassian-jira post \

# DELETE request
npx -y @aashari/mcp-server-atlassian-jira delete \
  --path "/rest/api/3/issue/PROJ-123/comment/12345"

Note: All CLI commands support:

• --output-format - Choose between toon (default, token-efficient) or json
• --jq - Filter response with JMESPath expressions
• --query-params - Pass query parameters as JSON string

Troubleshooting

"Authentication failed" or "403 Forbidden"

1. Check your API Token permissions:

   • Go to Atlassian API Tokens
   • Make sure your token is still active and hasn't expired

2. Verify your site name format:

   • If your Jira URL is https://mycompany.atlassian.net
   • Your site name should be just mycompany

3. Test your credentials:

   npx -y @aashari/mcp-server-atlassian-jira get --path "/rest/api/3/myself"
   

"Resource not found" or "404"

1. Check the API path:

   • Paths are case-sensitive
   • Use project keys (e.g., DEV) not project names
   • Issue keys include the project prefix (e.g., DEV-123)

2. Verify access permissions:

   • Make sure you have access to the project in your browser
   • Some projects may be restricted to certain users

"No results found" when searching

1. Try different search terms:

   • Use project keys instead of project names
   • Try broader search criteria

2. Check JQL syntax:

   • Validate your JQL in Jira's advanced search first

Frequently Asked Questions

What permissions do I need?

Your Atlassian account needs:

• Access to Jira with the appropriate permissions for the projects you want to query
• API token with appropriate permissions (automatically granted when you create one)

Can I use this with Jira Server (on-premise)?

Currently, this tool only supports Jira Cloud. Jira Server/Data Center support may be added in future versions.

How do I find my site name?

Your site name is the first part of your Jira URL:

• URL: https://mycompany.atlassian.net -> Site name: mycompany
• URL: https://acme-corp.atlassian.net -> Site name: acme-corp

What AI assistants does this work with?

Any AI assistant that supports the Model Context Protocol (MCP):

• Claude Desktop
• Cursor AI
• Continue.dev

Is my data secure?

Yes! This tool:

• Runs entirely on your local machine
• Uses your own Jira credentials
• Never sends your data to third parties
• Only accesses what you give it permission to access

Can I search across multiple projects?

Yes! Use JQL queries for cross-project searches. For example:

npx -y @aashari/mcp-server-atlassian-jira get \
  --path "/rest/api/3/search/jql" \
  --query-params '{"jql": "assignee=currentUser() AND status=\"In Progress\""}'

Debugging

Enable debug logging by setting the DEBUG environment variable:

# In Claude Desktop config
{
  "mcpServers": {
    "jira": {
      "command": "npx",
      "args": ["-y", "@aashari/mcp-server-atlassian-jira"],
      "env": {
        "DEBUG": "true",
        "ATLASSIAN_SITE_NAME": "your-company",
        "ATLASSIAN_USER_EMAIL": "your.email@company.com",
        "ATLASSIAN_API_TOKEN": "your_api_token"
      }
    }
  }
}

Debug logs are written to ~/.mcp/data/mcp-server-atlassian-jira.<session-id>.log

Check raw API responses: When responses are truncated, the full raw response is saved to /tmp/mcp/mcp-server-atlassian-jira/<timestamp>-<random>.txt with request/response details.

Migration from v2.x

Version 3.0 replaces 8+ specific tools with 5 generic HTTP method tools. If you're upgrading from v2.x:

Before (v2.x):

jira_ls_projects, jira_get_project, jira_ls_issues, jira_get_issue,
jira_create_issue, jira_ls_comments, jira_add_comment, jira_ls_statuses, ...

After (v3.0+):

jira_get, jira_post, jira_put, jira_patch, jira_delete

Migration examples:

• jira_ls_projects -> jira_get with path /rest/api/3/project/search
• jira_get_project -> jira_get with path /rest/api/3/project/{key}
• jira_get_issue -> jira_get with path /rest/api/3/issue/{key}
• jira_create_issue -> jira_post with path /rest/api/3/issue
• jira_add_comment -> jira_post with path /rest/api/3/issue/{key}/comment
• jira_ls_statuses -> jira_get with path /rest/api/3/status

Benefits of v3.0+:

• Full access to any Jira REST API v3 endpoint (not just predefined tools)
• JMESPath filtering for efficient data extraction
• Consistent interface across all HTTP methods
• TOON format for 30-60% token savings
