Summary
The first release of InstaHost WordPress MCP provides secure content-management abilities on top of the official WordPress MCP Adapter, with direct configuration for Automattic's desktop-client bridge.
What's new
- Dedicated MCP Adapter endpoint at
/wp-json/mcp/instahost-wordpress. - WordPress Abilities to inspect site metadata, list content, retrieve content, and search posts and pages.

Security
- MCP Adapter rejects anonymous transport access.
- The dedicated server requires the WordPress
edit_postscapability. - Per-post read, edit, and delete capability checks protect content operations.
- Publishing, private status transitions, and trashing require the corresponding WordPress capabilities.
- Non-forced deletion fails closed if WordPress recoverable trash is disabled.
- Revisions and autosaves are excluded, and password-protected content requires edit access.
- Write abilities are disabled by default.
- Content passes through WordPress sanitization and content APIs.
- OAuth is preferred where available; HTTPS is required when using Application Passwords.

Known issues and residual risks
- MCP protocol support follows the installed MCP Adapter version.
