Send a letter from GitHub Copilot CLI.

Add paperplane to GitHub Copilot CLI with one command and it can quote and send a real USPS letter — no account required, free sandbox mode included.

Free to preview — see the exact PDF before you pay. Sending starts at $1.99, no account required.

Set it up in GitHub Copilot CLI

Step 1

Connect

The standalone terminal tool, distinct from VS Code Copilot.

copilot mcp add --transport http paperplane https://sendpaperplane.com/api/mcp

Try it: free, nothing mailed

Tell your agent:

Using the paperplane tools, quote a 1-page certified letter to Property LLC, 1 Main St, Richmond VA 23220, then send it in sandbox mode.

Not on GitHub Copilot CLI? Any surface works.

The same three calls from the CLI, any MCP client or plain REST. Sandbox is free and mails nothing.

Common questions

Is this the same as VS Code’s Copilot?

No — this is the standalone copilot terminal tool, distinct from the VS Code Copilot integration, with its own config at ~/.copilot/mcp-config.json.

What tools does it get?

quote_letter, send_letter, and get_letter_status for mailing, plus buy_credits for pre-funding sends. Postcards are live (from $1.99) via the REST API’s format field, though not yet an MCP tool argument.

How much does sending cost?

Letters start at $1.99 for First-Class; Certified Mail starts at $12.99. Every quote shows the exact total before you approve anything, and sandbox mode is free.
