Common questions

Is Txn MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: TXN_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@txn-dev/mcp-server

MCP server for txn.dev - let any AI assistant manage agent payments.

Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Setup

Add to your MCP client config:

"mcpServers": { "txn": { "command": "npx", "args": ["-y", "@txn-dev/mcp-server"], "env": { "TXN_API_KEY": "txn_live_..." } } } }

Get your API key at txn.dev/dashboard/api-keys. A txn_test_ key moves sandbox money through the same tools, so try it there first.

Claude Code, in one line:

claude mcp add txn -e TXN_API_KEY=txn_test_... -- npx -y @txn-dev/mcp-server
