Overview

Description from the maker (original English)

Hosted two-way SMS bridge: your coding agent texts you when it needs an answer; you reply by SMS.

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs in the cloud
Transport: Streamable HTTP
Category: Chat & email
You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Runs in the cloudNothing to install; it connects over the internet

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http campfire https://api.campfiresms.com/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "campfire": {
      "url": "https://api.campfiresms.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "campfire": {
      "type": "http",
      "url": "https://api.campfiresms.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your choice stays on this device in a cookie; no account needed.

Values you fill in

Authorization secret required HTTP header
Per-installation bearer credential from your campfiresms.com account (sign up and verify your phone first). Use: Bearer . Requests without it get HTTP 401.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Campfire SMS 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: Authorization

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 (0.1.0) reached the registry 28 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?

Campfire SMS MCP

Text your agent. Campfire SMS is a hosted two-way SMS bridge: your agent texts you when it needs an answer or has a result, and you reply by SMS from your normal text inbox.

Don't pip install this repo or use an npx package name without an installation code. Start at [campfiresms.com](https://campfiresms.com).

How it works

Your agent opens a bridge and sends you a text when it needs input or finishes something.
You reply from your phone's normal text inbox. No phone app to install.
The agent retrieves your reply and keeps working with its own model, tools, and permissions. Campfire SMS handles phone enrollment, SMS delivery, the authenticated message queue, and routing.

Campfire SMS is not a service that gives an agent a phone number for other people to text. It connects your agent to you, the person running it.

Install (through campfiresms.com)

Sign up at campfiresms.com.
Verify your phone to start a free demo, no card required.
Copy the one-time install command from your account (Add computers → Add a computer or Bot → Create install command).

Full instructions: campfiresms.com/install.html

Local agents

For Codex, Claude Code, Grok Build, OpenCode, or another compatible MCP host on your computer. Run the command your account shows:

npx -y @campfiresms/setup YOUR_INSTALLATION_CODE

YOUR_INSTALLATION_CODE comes from your account. The command is single use and expires after 10 minutes; if it expires, create a new one.
Requires Node.js 18+ (with npx) and Python 3.12+.
Setup stores the installation credential locally and registers detected Codex and Grok Build CLIs. For other hosts, add a local MCP server named campfire using the command setup prints.
On Linux or a VM, run setup as the same non-root user as the agent, inside a Python virtual environment. Don't use sudo pip, system pip, or --break-system-packages. See the Linux/VM instructions.
Keep the computer awake and online with the agent session running. Campfire SMS does not wake a stopped local session.

To refresh a saved local connection: npx -y @campfiresms/setup update

Hosted MCP

Streamable HTTP endpoint:

https://api.campfiresms.com/mcp

It requires a per-installation bearer credential from your account, sent as Authorization: Bearer . It does not work without that credential: adding the URL alone (for example, through a directory's one-click install) gets HTTP 401.

To get the credential, run your account's install command with --credential-only (needs Node.js 18+, no Python or pip). Put the credential only in your client's secure credential settings.

Example for Grok Bot cloud routines: connect the hosted MCP with the credential, then set up an active webhook routine and save its URL and key under Grok Bot 24/7 wake in your account. An incoming text can then start the routine while your PC is off. See the Grok Bot walkthrough.

Tools

Tool	Purpose
`campfire_open_bridge`	Open (or reuse) an SMS bridge to your verified phone
`campfire_send_message`	Send you a text
`campfire_check_messages`	Retrieve your pending replies (they repeat until acknowledged)
`campfire_ack`	Acknowledge message IDs after handling them
`campfire_close_bridge`	Close the bridge when the session is done

Limits and safety

SMS replies don't grant the agent new permissions. They can steer work within the agent's existing permissions; native approvals stay in the agent.
SMS is not end-to-end encrypted. Don't text passwords, credentials, payment details, or other secrets.
Each text sent or received counts as one message. Messaging pauses when your messages run out. See pricing.

About this repository

This repository holds the source of the earlier v0.1.1 Python connector, for reference. The current @campfiresms/setup installer bundles the maintained connector. For a new installation, use the steps above, not this source.
