An open-source **[Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server** for **Atlassian Confluence** that lets AI assistants like **Claude** and **Windsurf** read, create, search, and manage Confluence wiki pages. Works with **Confluence Cloud**, **on-premise Server**, and **Data Center** deployments — connect your AI coding agent to your team's knowledge base in seconds via `npx`.

## Why atlassian-confluence-mcp-server?

- ✅ Only MCP server supporting **Cloud + Server + Data Center** in one package
- ✅ **47 tools** — most comprehensive Confluence MCP available
- ✅ Zero config via `npx` — no install needed
- ✅ PAT, Basic Auth, and API token support
- ✅ Actively maintained with provenance-signed releases

## Prerequisites

- **Node.js 22.12+**
- A Confluence instance (Cloud or Server/Data Center 7.9+)
- Authentication credentials (PAT or username/password)

## Installation

### Via npx (no install required)

```bash
npx atlassian-confluence-mcp-server
```

### Global install

```bash
npm install -g atlassian-confluence-mcp-server
```

### From source

```bash
git clone https://github.com/anuragagrawal0430/atlassian-confluence-mcp-server.git
cd atlassian-confluence-mcp-server
npm install
npm run build
```

## Configuration

All configuration is passed through **environment variables**. Never hard-code credentials.

| Variable | Required | Description |
|---|---|---|
| `CONFLUENCE_BASE_URL` | Yes | Root URL of your Confluence instance |
| `PAT` | See below | API token (Cloud) or Personal Access Token (Server/DC) |
| `CONFLUENCE_USERNAME` | Cloud only | Your Atlassian account email |
| `CONFLUENCE_PASSWORD` | Alt auth | Password or API token for Basic Auth |
| `CONFLUENCE_READ_ONLY` | No | Defaults to `true`; set to `false` to allow mutating tools |
| `CONFLUENCE_ENABLE_DESTRUCTIVE_TOOLS` | No | Defaults to `false`; set to `true` to allow delete/permission mutation tools |
| `CONFLUENCE_ENABLED_TOOLS` | No | Optional comma-separated allowlist of tool names to expose |
| `CONFLUENCE_ALLOWED_SPACES` | No | Optional comma-separated allowlist of space keys for requests with `spaceKey`/`destinationSpaceKey` |
| `CONFLUENCE_ALLOW_INSECURE_HTTP` | No | Defaults to `false`; only allows `http://` for localhost/loopback when set to `true` |
| `CONFLUENCE_MAX_ATTACHMENT_BYTES` | No | Client-side max file size for `confluence_upload_attachment` in bytes (default: `52428800` / 50 MB). Confluence may still enforce a lower instance limit. |
| `CONFLUENCE_UPLOAD_ALLOWED_DIRS` | No | **Security:** Comma-separated allowlist of absolute directory paths from which file uploads are allowed. Empty by default (uploads disabled). |

### Confluence Cloud

Cloud API tokens are generated from your Atlassian account and require **both** your email and the token:

```env
CONFLUENCE_BASE_URL=https://your-site.atlassian.net
CONFLUENCE_USERNAME=you@example.com
PAT=your-api-token
```

1. Go to <https://id.atlassian.com/manage-profile/security/api-tokens>
2. Click **Create API token**, give it a label, and copy the value
3. Set `CONFLUENCE_USERNAME` to your Atlassian account email
4. Set `PAT` to the copied API token

### Confluence Server / Data Center (7.9+)

Server and Data Center instances use a Personal Access Token with **Bearer** authentication. Only the token is needed:

```env
CONFLUENCE_BASE_URL=https://confluence.example.com
PAT=your-personal-access-token
```

1. Navigate to **Profile > Settings > Personal Access Tokens**
2. Create a token with the required permissions
3. Copy the token value

### Basic Authentication (fallback)

For older Server versions without PAT support, use username/password:

```env
CONFLUENCE_BASE_URL=https://confluence.example.com
CONFLUENCE_USERNAME=your-username
CONFLUENCE_PASSWORD=your-password
```

### Security Controls (important)

The server now uses secure defaults to reduce prompt-injection blast radius and credential leakage risk:

- `CONFLUENCE_READ_ONLY=true` by default
  - Mutating tools are disabled unless you set `CONFLUENCE_READ_ONLY=false`.
- `CONFLUENCE_ENABLE_DESTRUCTIVE_TOOLS=false` by default
  - `confluence_delete_page`, `confluence_delete_space`, and `confluence_set_page_permissions` remain disabled unless explicitly enabled.
- `CONFLUENCE_ENABLED_TOOLS` (optional)
  - Restrict exposure to an explicit tool allowlist.
- `CONFLUENCE_ALLOWED_SPACES` (optional)
  - Restrict requests that include `spaceKey` / `destinationSpaceKey` to an approved set.
- `CONFLUENCE_ALLOW_INSECURE_HTTP=false` by default
  - HTTPS is required unless this is set to `true`.
  - Even when enabled, insecure HTTP is restricted to localhost/loopback only.
- `CONFLUENCE_MAX_ATTACHMENT_BYTES` (optional, default 50 MB)
  - Caps how large a host file `confluence_upload_attachment` will read before calling Confluence.
  - Independent of the instance "Attachment Maximum Size" admin setting (not exposed via public REST).
- `CONFLUENCE_UPLOAD_ALLOWED_DIRS` (optional, defaults to empty)
  - Explicitly restricts which host directories the MCP server is allowed to read files from when uploading attachments.
  - If not configured, file uploads from the host filesystem are entirely disabled.

Example (enable safe writes, keep destructive tools disabled):

```env
CONFLUENCE_READ_ONLY=false
CONFLUENCE_ENABLE_DESTRUCTIVE_TOOLS=false
```

Example (strict allowlist):

```env
CONFLUENCE_ENABLED_TOOLS=confluence_get_page,confluence_search_pages,confluence_get_page_body_chunk
```

Example (space-level allowlist):

```env
CONFLUENCE_ALLOWED_SPACES=ENG,SECURITY
```

type=page AND lastModified > now("-7d")

# Title search
type=page AND title~"Meeting Notes"

# Pages created by current user
type=page AND creator=currentUser()
```

## Page Body Format

Pages use Confluence storage format (XHTML):

```html
<p>This is a paragraph.</p>
<h1>Heading 1</h1>
<ul>
  <li>Item 1</li>
  <li>Item 2</li>
</ul>
<ac:structured-macro ac:name="code">
  <ac:parameter ac:name="language">javascript</ac:parameter>
  <ac:plain-text-body><![CDATA[console.log("Hello");]]></ac:plain-text-body>
</ac:structured-macro>
```

### Editing Very Large Pages

When a page body is very large (for example hundreds of KB), avoid sending the full body through `confluence_update_page`.

Recommended workflow:

1. Use `confluence_get_page_body_chunk` to inspect the relevant part of the page.
2. Use one of:
   - `confluence_patch_page` for exact find/replace edits.
   - `confluence_replace_page_range` for replacing a specific middle range.
   - `confluence_append_to_page` for incremental append/prepend updates.

Notes:

- Offset-based range replacement is the most reliable mode for storage XHTML.
- Line-based replacement requires actual newline characters in the stored body.
- These tools still perform a full Confluence update under the hood, but the full body remains server-side.

## Security

- **Credentials** are read exclusively from environment variables — never hard-coded.
- **Input validation** — all user-supplied parameters are validated and sanitized before use.
- **CQL injection prevention** — user input interpolated into CQL queries is escaped.
- **URL path encoding** — all dynamic path segments are encoded with `encodeURIComponent`.
- **Request timeouts** — all HTTP requests have a 30-second timeout to prevent hanging.
- **Error sanitization** — API error responses are truncated and stripped of HTML before surfacing.
- **Pagination limits** — query limits are clamped to a safe maximum (100) to prevent abuse.
