Install Twitter Signal in Claude Code

What you need first

• Claude Code, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_CDP_API_KEY_ID,YOUR_CDP_API_KEY_SECRET,YOUR_CDP_WALLET_SECRET.

Steps

1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.

claude mcp add --env CDP_API_KEY_ID=YOUR_CDP_API_KEY_ID --env CDP_API_KEY_SECRET=YOUR_CDP_API_KEY_SECRET --env CDP_WALLET_SECRET=YOUR_CDP_WALLET_SECRET --transport stdio twitter-signal-mcp -- npx -y [email protected]

2. Replace YOUR_CDP_API_KEY_ID,YOUR_CDP_API_KEY_SECRET,YOUR_CDP_WALLET_SECRET with your own values.
3. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of twitter-signal-mcp.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Claude Code sees. Install it, or write the full path of npx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
