Install: uvx mcp-atlassian-extended | PyPI | MCP Registry | Changelog

mcp-atlassian-extended is a Model Context Protocol (MCP) server for Jira and Confluence. It gives an AI assistant 22 tools, 15 resources, and 5 prompts for Jira and Confluence work. The tools create and update issues with custom fields, link issues, manage attachments, and search users. They also run agile boards and sprints, track project versions (API v2), read team calendars, and plan sprint capacity. It extends mcp-atlassian with zero tool overlap.

The server supports the MCP 2026-07-28 specification (often called MCP 2.0) and stays compatible with 2025-11-25 clients. It works with Claude Desktop, Claude Code, Cursor, Windsurf, VS Code Copilot, and any MCP-compatible client.

The server supports Jira Cloud, Jira Data Center, Confluence Cloud, and Confluence Data Center (self-hosted). It needs no Atlassian Premium plan.

Built with FastMCP, httpx, and Pydantic.

Protocol support

• The server implements the MCP 2026-07-28 specification, often called MCP 2.0.
• It stays compatible with 2025-11-25 clients.
• Transports: stdio (default) and streamable-http (recommended for remote clients). The sse transport still works, but the 2026-07-28 specification deprecates it, so the server prints a warning.
• The server uses no roots, sampling, logging, elicitation, or resource subscriptions. The 2026-07-28 deprecations do not affect it.
• Built on FastMCP 4.x and the MCP Python SDK 2.x.

Relationship to mcp-atlassian

This project runs alongside mcp-atlassian, not as a replacement. Configure both servers:

• mcp-atlassian handles: issues, search, transitions, comments, worklog, pages, Confluence search
• mcp-atlassian-extended handles: attachments, agile, users, fields, versions (API v2), calendars, time-off

There is no tool overlap — this server only implements tools that mcp-atlassian lacks.

Configuration

Jira Cloud (Basic Auth)

Jira Data Center / Self-Hosted (Bearer Token)

The server checks these environment variables in order — first match wins:

1. JIRA_PAT
2. JIRA_PERSONAL_TOKEN
3. JIRA_TOKEN

Basic auth wins. If you set both JIRA_USERNAME and JIRA_API_TOKEN, the server uses Basic auth and ignores any personal access token. The server uses Bearer auth only when the Cloud pair is incomplete. To force Bearer, unset JIRA_USERNAME and JIRA_API_TOKEN.

Confluence Cloud (Basic Auth)

Confluence Data Center / Self-Hosted (Bearer Token)

The server checks these environment variables in order — first match wins:

1. CONFLUENCE_PAT
2. CONFLUENCE_PERSONAL_TOKEN
3. CONFLUENCE_TOKEN

Basic auth wins here too: CONFLUENCE_USERNAME + CONFLUENCE_API_TOKEN take precedence over any personal access token.

All Confluence calendar tools require the Team Calendars add-on (/rest/calendar-services/1.0/). On instances without it every calendar tool returns a 404 with a hint naming the add-on.

    custom_fields={"customfield_10004": 5})

Security Considerations

• Token scope: For Jira Cloud, use API tokens scoped to the minimum required permissions. For Data Center, use PATs with project-level access.
• Read-only mode: Set ATLASSIAN_READ_ONLY=true to disable all write operations (create, update, delete, upload). The server enforces this before any API call.
• File upload validation: jira_upload_attachment validates file paths (no traversal, max 100MB, file must exist).
• Download path restriction: jira_download_attachment accepts only relative paths resolved within the working directory. It rejects absolute paths and path traversal (../).
• Download URL validation: The server validates each attachment download URL against the configured Jira URL domain to prevent SSRF.
• SSL verification: The server enables SSL verification by default for Jira and Confluence. Disable it only for self-signed certificates in trusted networks.
• MCP tool annotations: Each tool declares readOnlyHint, destructiveHint, and idempotentHint for client-side permission prompts.
• No credential storage: The server reads tokens from environment variables at startup. It never stores them.

Rate Limits & Permissions

Rate Limits

Jira Cloud enforces per-user rate limits. When rate-limited, tools return a 429 error with a hint to wait. Confluence Calendar API calls may be slower due to the Team Calendars plugin architecture.

Required Permissions

CLI & Transport Options

# Default: stdio transport (for MCP clients)
uvx mcp-atlassian-extended

# HTTP transport. Use streamable-http for remote clients.
uvx mcp-atlassian-extended --transport streamable-http --port 9000

# sse still works, but the MCP 2026-07-28 spec deprecates it. The server prints a warning.
uvx mcp-atlassian-extended --transport sse --host 127.0.0.1 --port 8000

# CLI overrides for config
uvx mcp-atlassian-extended --jira-url https://jira.example.com --jira-token xxx --read-only

The server loads .env files from the working directory automatically via python-dotenv.

Partial configuration: You configure Jira and Confluence independently. Set either or both. The server always advertises all 22 tools. A tool for an unconfigured product returns a "not configured" error that names the variables to set. The server does not fail at startup.

FAQ

Does it support the MCP 2026-07-28 spec (MCP 2.0)?

Yes. It implements the MCP 2026-07-28 specification (MCP 2.0) and stays compatible with 2025-11-25 clients.

Which transports does it support?

It supports stdio (the default) and streamable-http (recommended for remote clients). The sse transport still works, but the 2026-07-28 specification deprecates it.

Is it read-only safe?

Yes. Set ATLASSIAN_READ_ONLY=true to disable every write operation. The server enforces this before any API call.

Does it work with self-hosted Jira and Confluence?

Yes. It supports Jira Cloud, Jira Data Center, Confluence Cloud, and Confluence Data Center. It uses the Jira REST API v2, which works on both Cloud and Server/Data Center.

What permissions and token scopes does it need?

It needs a Jira API token (Cloud) or a personal access token (Data Center). Each operation needs the matching Jira permission. See Required Permissions.

Does it replace mcp-atlassian?

No. It runs alongside mcp-atlassian with zero tool overlap. mcp-atlassian handles core search and CRUD. This server adds attachments, agile boards, versions, and calendars.

Do the Confluence tools need an add-on?

Yes. The three Confluence calendar tools need the Team Calendars add-on. Without it, they return a 404 with a hint that names the add-on.

How many tools does it provide?

It provides 22 tools, 15 resources, and 5 prompts for Jira and Confluence.
