TwitterAPI MCP Server

A Model Context Protocol (MCP) server that provides access to Twitter data through the TwitterAPI.io service. This server enables Claude and other MCP clients to interact with Twitter's ecosystem without requiring Twitter developer account approval.

> Attribution: This project is a fork of kinhunt/twitterapi-mcp with bug fixes and improvements to match the official TwitterAPI.io documentation.

Features

- User Information: Get detailed user profiles, followers, and following lists
- Tweet Operations: Search tweets, get tweet details, replies, and user timelines
- Search Capabilities: Advanced search for both tweets and users
- Write Actions: Post tweets and interact with content (requires login)
- Pagination Support: All list endpoints support cursor-based pagination
- Enterprise Ready: Proxy support and robust error handling
- No Twitter Auth: Uses TwitterAPI.io which doesn't require Twitter developer approval

await login_user({
user_name: "your_username",
email: "your_email@example.com",
password: "your_password",

Pagination

All list endpoints return paginated results with cursor-based navigation:

`json
{
"data": [...],
"has_next_page": true,
"next_cursor": "cursor_string_for_next_page"
}
`

To get the next page, pass the next_cursor value as the cursor parameter in your next request.

Error Handling

The server handles common errors:

| Error | Cause | Solution |
|-------|-------|----------|
| 401 Unauthorized | Invalid API key | Check your TWITTERAPI_API_KEY |
| 402 Payment Required | Insufficient credits | Add credits at TwitterAPI.io dashboard |
| 429 Rate Limited | Too many requests | Wait and retry, or reduce request rate |
| 400 Bad Request | Invalid parameters | Check parameter names and formats |

Security Considerations

- Store API keys as environment variables, never in code
- Login credentials are used only for authentication, not stored persistently
- All API requests use HTTPS
- Proxy support available for enterprise security requirements
- The login_cookie from login is stored in memory only for the session

Troubleshooting

$3


- Verify your API key is correct
- Check that TWITTERAPI_API_KEY environment variable is set

$3

- Add credits to your TwitterAPI.io account
- Check your usage at the dashboard

$3

- Ensure Node.js >= 18.0.0 is installed
- Run npm run build to compile TypeScript
- Check for error messages in stderr

$3

- Verify proxy URL format: http://user:pass@host:port
- Test proxy connectivity independently
- For HTTPS proxies, use HTTPS_PROXY variable
