Hosted two-way SMS bridge between a phone and coding agents.
Copy the AI prompt to install this server into Claude Code, Cursor, or another agent β or use 1-click editor setup below.
Clients with native remote MCP support can connect directly to this URL instead of the install method above.
Campfire MCP connects a local Codex session to the Campfire SMS transport. Campfire carries messages; your Codex runtime supplies the model, tools, and permissions.
Requires Python 3.12 or newer.
configure asks for the service URL and the one-time installation credential
shown after signup. It stores the credential under your local user profile with
restricted permissions, validates it with Campfire, and registers the STDIO
server through codex mcp add when the Codex CLI is available.
Restart ChatGPT desktop, Codex CLI, or the IDE extension after configuration.
The clients share the same Codex MCP configuration on a host. You can inspect
the connection with /mcp or:
Then ask Codex to open the Campfire bridge. While the Codex session is active, use the Campfire tools to check and acknowledge inbound SMS or send a concise SMS update.
A message matching the enrolled number means Campfire verified control of that number during enrollment and received this message through an authenticated provider webhook. It is not permanent proof of human identity.
Campfire SMS is a lower-trust steering channel. It cannot grant tools, permissions, credentials, secret disclosure, destructive authority, or replace Codex's native approval system. SMS is not end-to-end encrypted; do not send passwords, payment details, or sensitive data.
Advanced users may set CAMPFIRE_API_URL, CAMPFIRE_CREDENTIAL,
CAMPFIRE_CONFIG_PATH, and CAMPFIRE_BRIDGE_STATE_PATH. Environment values
override the saved local configuration.
Revoke the installation from Campfire setup, then run:
