Eliodata MCP Bridge

Changelog

4.2.2

• New: a header with the plugin navigation (Snippets, New snippet, Assignments, Import / Export, MCP tools) stays at the top of every plugin screen.
• Fix: snippets written to the Code Snippets tables are now checked for PHP syntax errors before they are stored (PHP scopes only), as native snippets already were.
• Fix: the Code Snippets cache is cleared after a snippet is created, updated or deleted through the API.
• Removed the permanent information notice shown on every plugin screen; runtime notices are now in French.

4.2.1

• MCP screen redesigned: one catalog listing every tool once, with where it is visible (read and write, or write only), its parameters and its JSON schema on demand.
• The catalog explains why a custom tool is hidden from the read profile (not declared read-only, or declared read-only but not called with GET).
• Tester: the profile follows the tool, required arguments are prefilled from the schema, the last arguments are kept after a run, a write tool asks for confirmation, and the result shows status, duration and a copy button.
• Custom tool form: folded until needed, live JSON check, method and argument mode kept consistent, and a failed save keeps what was typed.
• Admin menu and page titles are now all in French, like the rest of the screens.

4.2.0

• Plugin renamed to “Eliodata MCP Bridge” (same slug, settings and snippets are preserved).
• New: MCP endpoints to discover and run tools (/mcp/tools, /mcp/call).
• New: per-site custom MCP tools, managed from the admin screen or through /mcp/custom-tools.
• New: “MCP” admin screen to browse and test tools from WordPress.
• New: built-in MCP tools for snippets (list, get, create, update, delete) with read and write profiles.
• New: read-only Application Passwords. Add [readonly] to the password name: every write request made with it is refused on the whole REST API (not only the plugin routes), and XML-RPC is blocked.
• New: PHP syntax check before a snippet is saved. The REST API rejects invalid code; the admin screen and the importer keep it but deactivated.
• New: a snippet that causes a fatal error is deactivated automatically, including errors raised later by its callbacks. The error is shown in the admin.
• New: safe mode. Add define('ELIODATA_SNIPPET_HUB_SAFE_MODE', true); to wp-config.php to stop running snippets.
• Improved: snippets never run on the plugin admin screens and on the /ide/v1/ routes, so a broken snippet can always be fixed.
• Changed: snippets that target all content now run on init on every request, including REST API, cron and AJAX requests. Snippets that target post types or specific posts still wait for the main query on the front end. Conditional tags such as is_page() must be called inside a hook. To keep the previous timing, add define('ELIODATA_SNIPPET_HUB_LEGACY_TIMING', true); to wp-config.php.
• Changed: snippet code is compiled once per version in a private folder of uploads (eliodata-snippet-hub), instead of a temporary file on every request.
• Changed: on multisite, managing snippets requires the manage_network_options capability (super admins). Filterable with eliodata_snippet_hub_required_capability.
• Fixed: custom MCP tools are listed in the MCP catalog (read-only GET tools for the read profile, all tools for the write profile).
• Fixed: snippet changes made through the REST API and bulk actions now clear the object cache.
• New: optional support for the Code Snippets plugin tables as a secondary snippet engine.
• New: dedicated eliodata_snippet_hub_manage capability, filterable via eliodata_snippet_hub_api_capability and eliodata_snippet_hub_mcp_capability.
• Improved: snippet code can be sent base64-encoded (code_b64) to avoid transport issues with special characters.
• Security: removed all site-specific code from the public package; only generic snippet tools and site-defined custom tools are exposed.

2.0.0

• Native snippet engine and secure REST bridge for remote snippet management from Trae AI and VS Code.
• Admin screens for snippets, content targeting, and import/export (JSON, NDJSON).
