Installation

git clone https://github.com/DataWhisker/x-mcp-server.git
cd x-mcp-server
npm install
npm run build

Authentication

The server supports two authentication methods. You need at least one configured.

OAuth 1.0a (Required for basic operations)

Works for all post/engagement/search/user operations.

| Environment Variable | Description |
|---------------------|-------------|
| TWITTER_API_KEY | Consumer Key (API Key) |
| TWITTER_API_SECRET | Consumer Secret (API Key Secret) |
| TWITTER_ACCESS_TOKEN | User Access Token |
| TWITTER_ACCESS_SECRET | User Access Token Secret |

Setup: In the X Developer Portal:
1. Create a project and app
2. Enable OAuth 1.0a under "User authentication settings"
3. Set permissions to "Read and Write"
4. Generate Consumer Keys and Access Tokens

OAuth 2.0 (Required for media upload)

The v1.1 media upload endpoint was sunset in June 2025. Media upload now requires OAuth 2.0 via the v2 upload API.

Option A - Direct access token:

| Variable | Description |
|----------|-------------|
| TWITTER_OAUTH2_ACCESS_TOKEN | OAuth 2.0 user access token (expires in 2 hours) |

Option B - Auto-refresh (recommended for long-running servers):

| Variable | Description |
|----------|-------------|
| TWITTER_CLIENT_ID | OAuth 2.0 Client ID |
| TWITTER_CLIENT_SECRET | OAuth 2.0 Client Secret (optional for public clients) |
| TWITTER_OAUTH2_REFRESH_TOKEN | OAuth 2.0 Refresh Token |

Tokens are auto-refreshed and persisted to ~/.x-mcp-tokens.json.

Setup: In the X Developer Portal:
1. In your app settings, enable OAuth 2.0
2. Set type to "Confidential client" or "Public client"
3. Add a callback URL
4. Request scopes: tweet.read, tweet.write, users.read, media.write, offline.access, like.read, like.write, bookmark.read, bookmark.write, follows.read, block.read, mute.read, list.read

Media Support

- Images: PNG, JPEG, GIF, WEBP (max 5MB)
- Videos: MP4, MOV, AVI, WEBM, M4V (max 512MB, streamed chunked upload)
- Cannot attach both image and video to the same post
- Requires OAuth 2.0 credentials (v1.1 upload sunset June 2025)
- Path restriction: Only files within your home directory or system temp directory can be uploaded (prevents path traversal)

Security

- Input validation: Tweet IDs must be numeric (1-20 digits), usernames must match [A-Za-z0-9_]{1,15}
- Media path restriction: Upload paths are validated against an allow-list (home directory, temp directory)
- Token storage: OAuth 2.0 tokens persisted to ~/.x-mcp-tokens.json with 0o600 permissions (Unix). On Windows, file permissions are not enforced by the OS - protect the file via NTFS ACLs or use environment variables instead.
- Error sanitization: X API error details are logged server-side only; sanitized messages are returned to MCP clients
- Refresh mutex: Concurrent token refresh attempts are deduplicated to prevent race conditions

Pairing with GetXAPI for Cheaper Read Operations (Optional)

For users who need a cheaper or higher-rate-limit option for read-only Twitter (X) operations such as tweet search, profile lookup, and follower lists, this project can be paired with GetXAPI, a budget Twitter / X data API priced at $0.05 per 1K tweets versus the official X API basic tier at $200 / month.

Two integration patterns:

1. Run side-by-side in your AI client. Keep this project for its primary workflow and add the official GetXAPI MCP server for read-heavy tasks. Each tool name routes to the backend best suited for that operation.

2. Add a backend toggle. For a code-level reference of an optional alternative backend behind a single env variable, see the PR pattern merged into a sibling project.

GetXAPI quick start:

- Signup with $0.50 free credit (no card required): https://getxapi.com/signup
- Official GetXAPI MCP server: https://github.com/getxapi/getxapi-mcp
- npm: @getxapi/mcp
- Pay-per-call pricing: $0.001 / call, $0.05 / 1K tweets

This pairing is fully optional. No behavior change for existing users.
