# MCP Governance Hook Config Changelog

> What changed in each version of the MCP Governance hook config your MDM deploys.

Each version below is a new hook config to download from the Deployment tab and re-upload to your MDM. Enrollment doesn't change between versions. For the full setup, see [Deploying to Your Fleet](/docs/mcp-governance-rollout).

## \[1.2] - 2026-10-15

### Changed

* Claude Cowork tool calls now appear under their own **Cowork** harness in MCP Tool Usage, instead of as Claude Code. The Claude Code hook sends which client made the call.
* The hooks ignore each user's personal `~/.curlrc`, so a local curl setting can't stop calls from reaching Lumos.

### Action

* Download the hook config and replace the old one in your MDM. Until you do, Cowork calls keep showing as Claude Code.
* Users who installed through the per-user install page re-run it. Codex asks them to trust the updated hooks again in `/hooks`.

## \[1.1] - 2026-10-15

### Changed

* On macOS, one configuration profile now carries the hooks for both Claude Code and Codex. Codex no longer needs a separate `requirements.toml`.
* The new profile replaces the Claude Code-only profile on each Mac instead of sitting beside it.
* Linux is no longer part of the MDM setup. Linux users install through the per-user install page.

### Action

* Download the macOS profile and replace the old one in your MDM.
* Don't deploy a second profile for the `com.openai.codex` preference domain. Two profiles for the same domain collide. A `/etc/codex/requirements.toml` file on disk is fine.

## \[1.0] - 2026-10-13

### Added

* Hook configs carry a version, and each tool call reports the version of the config that sent it. The Deployment tab shows how many calls come from each version.
* Calls from configs deployed before versioning appear as **No version reported**.

### Action

* Download the hook config and re-upload it to your MDM, so the Deployment tab can show which devices are current.
