Inspects and configures the security headers a Power Pages site sends to browsers — Content Security Policy, frame and clickjacking protection, cross-origin sharing, cookie behavior, and related site settings. Identifies gaps and walks the user through fixes. Use when the user wants to review headers, fix CSP errors, allow embedding in another site, control cross-origin access, harden cookie settings, or asks "are my browser settings safe?", "fix my CSP", "set up CORS" — even if they only…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Plugin check**: Run `node "${PLUGIN_ROOT}/scripts/check-version.js"` — if it outputs a message, show it to the user before proceeding.
# Manage Headers
Inspect and configure the HTTP security headers for a Power Pages site. Headers are configured as `HTTP/*` site settings stored in `.powerpages-site/site-settings/` YAML files.
**Initial request:** $ARGUMENTS
## Gotchas
- **Site settings are YAML files.** Each header is a separate `.yml` file in `.powerpages-site/site-settings/`. The file name uses `-` instead of `/` (e.g., `HTTP/X-Frame-Options` → `http-x-frame-options.sitesetting.yml`).
- **Absent = no header.** When a site setting is absent, the runtime omits that header entirely (except CSP on new sites — see headers-reference.md).
- **HSTS and Cache-Control are platform-managed.** Do not try to set `HTTP/Strict-Transport-Security` — the runtime does not recognize it and the setting has no effect.
- **Maker-mode bypasses headers.** Requests from Power Pages Studio skip all `HTTP/*` header emission. Verify headers in an incognito tab, not the studio preview.

How to install
mdr add microsoft/power-platform-skills/manage-headers@sha256:38d1cebd6184d27fThe line at the top of this page pins the label git:20260619.f001179, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
