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.

git clone https://github.com/Jing-yilin/twitterapi-mcp-server.git
cd twitterapi-mcp-server
npm install
npm run build

Running Tests

# Using bun
bun test

# Or with npm (requires bun installed)
npm test

Testing the Server Manually

# Set your API key
export TWITTERAPI_API_KEY="your_api_key"

# Test tools list
echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}' | node build/index.js

# Test a tool call
echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "get_user_by_username", "arguments": {"username": "elonmusk"}}}' | node build/index.js

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

"Unauthorized" error

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

"Credits not enough" error

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

Server not starting

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

Proxy issues

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