# Connect an assistant to Threadpacket

Server address: `https://threadpacket.com/mcp`

Add the server once in each assistant you use, then sign in with your username and access code. No team yet? Choose **Create a team** on the sign-in page, or create one at https://threadpacket.com/join.

### Claude
Claude on the web, in the desktop app and in Cowork. Add it once: the connector follows your Claude account to every computer. Tested with Threadpacket in the Claude desktop app on Windows: sign-in, send, and files once the server is an allowed domain (below).
1. Open [Add Threadpacket to Claude](https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Threadpacket&connectorUrl=https%3A%2F%2Fthreadpacket.com%2Fmcp), or go to [Customize > Connectors](https://claude.ai/customize/connectors) and select **+ Add** > **Add custom connector**.
2. Confirm the name **Threadpacket** and the server address above, then select **Continue** and **Add**.
3. Select **Connect**, sign in with your username and access code, or choose **Create a team** if you're new, and approve access.

Shortcut: [open the dialog with the name and address filled in](https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Threadpacket&connectorUrl=https%3A%2F%2Fthreadpacket.com%2Fmcp), then continue from step 4.

**Note:** To attach files, add `threadpacket.com` to the allowed domains in Claude's Settings > Capabilities.

On Team or Enterprise plans, an owner adds the connector first in Organization settings > Connectors.

### ChatGPT
Add it once: the connection follows your ChatGPT account to chatgpt.com and the Codex app, on every computer. Tested with Threadpacket on Windows: sign-in, send and files, used from the Codex app.
1. Open [ChatGPT Plugins](https://chatgpt.com/plugins), click **+**, and select **Add custom MCP server**.
2. Name it **Threadpacket**, paste the server address above, choose **OAuth**, and select **Create as a plugin**.
3. Open [personal plugins](https://chatgpt.com/plugins?view=personal), install Threadpacket, then sign in with your username and access code, or choose **Create a team** if you're new, and approve access.
Custom MCP servers require a ChatGPT plan or workspace with developer mode enabled.

### Codex
The Codex app: add Threadpacket once in ChatGPT (ChatGPT tab) and it appears in the Codex app on every computer. Tested with Threadpacket in the Codex app on macOS and Windows: sign-in, send, read and files. The commands below are for the Codex CLI and IDE extension.

Using the Codex desktop app? Add Threadpacket once under **ChatGPT** and it syncs automatically. Below is for the Codex CLI.

   ```sh
   codex mcp add threadpacket --url https://threadpacket.com/mcp
   ```
2. Sign in with your username and access code, or choose **Create a team** if you're new, and approve access:

   ```sh
   codex mcp login threadpacket
   ```
3. Start a new Codex session.

### Hermes
Tested with Threadpacket on macOS (Hermes Agent CLI and gateway): sign-in, files, send, read and revoke.
1. Add the server with OAuth:

   ```sh
   hermes mcp add threadpacket --url https://threadpacket.com/mcp --auth oauth
   ```
2. Sign in and approve access:

   ```sh
   hermes mcp login threadpacket
   ```
3. Start a new chat or run `/reload-mcp`.
On a headless gateway (such as Telegram), approve sign-in from the Hermes dashboard under MCP Servers.

## Then

Say “send a packet to anna” in one assistant and “continue the packet from joe” in the other. To read a packet and see its files in a browser, or upload a file from a phone, sign in to Packets at https://threadpacket.com/packets.
