Common questions

Is Paper Plane Post safe?

It passed 3 of 3 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 9 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

Paper Plane Post for agents

Create and send an AI-illustrated postcard anywhere in the world.

Start an unpaid draft from your assistant, then open the returned link to review the photo, finish the note and address, and pay for printing and mailing on Paper Plane Post.

Connect

Add this remote MCP server with Streamable HTTP:

https://api.paperplanepost.com/v1/mcp

No account, API key, or authentication header is required. The root plugin.json and mcp.json form a portable Agent Plugin that Cursor Directory can discover from this repository URL. The MCP configuration is:

{

"mcpServers": { "paper-plane-post": { "type": "streamable-http", "url": "https://api.paperplanepost.com/v1/mcp" } } }

start_postcard accepts one photo source: a public HTTPS photo_url, actual file bytes encoded as photo_base64, or the host's supported file input. Include a note and any known recipient fields, or leave them for the website. show_postcard displays the handoff for an existing draft URL without creating another draft. Tool calls never charge money or mail a postcard. Draft links expire after seven days.

Use actual file bytes, never base64 invented from an image. Missing note or address fields don't block a draft. The website handles review, payment, and mailing; order lookup is unavailable through this server.

Packages

  • ChatGPT and Codex: plugin manifest, MCP configuration, icon, and packaging helper.
  • Claude: plugin manifest, MCP configuration, postcard skill, file-upload helper, and packaging helper.
  • server.json: official MCP Registry metadata for com.paperplanepost/office.

These are distribution sources. A package archive or registry listing does not imply approval in an AI app's directory. Build with Bun and the system zip command. From this repository's root:

bun chatgpt/docs/package.ts

bun claude/docs/package.ts

Archives are written under dist/ in the working directory. The builders use explicit file allowlists; environment files and review evidence aren't packaged.
