Single Grain keeps publishing AI-for-marketing how-tos, not product changes
A side-by-side editorial comparison of Bludit and Metricool — release velocity, themes, recent moves, and the top alternatives to consider.
A flat-file CMS with a long CVE history just wired its API up for MCP.
Bludit ships every few weeks, and almost every release carries a security fix: an authentication bypass and arbitrary file upload in 3.18.4, an authenticated RCE via file upload plus .htaccess bypass in 3.20.0, a path traversal in the API files endpoint in 3.21.0, and session invalidation for disabled users in 3.22.0. Around that, the work is editor and dashboard maintenance, theme additions and a plugin hook for injecting editor toolbar buttons.
Metricool's feed is all how-to guides, now including one for its ChatGPT connection.
Metricool published five more articles on November 12 and 13: lead generation, posting frequency, community building, holiday campaigns and a guide to connecting Instagram to ChatGPT through Metricool. The ChatGPT guide is the only one tied to a product capability, and it documents an existing connection rather than announcing a release. Earlier entries were careers explainers and walkthroughs of the approval and inbox tools.

Around that, the work is editor and dashboard maintenance, theme additions and a plugin hook for injecting editor toolbar buttons.
Two threads run in parallel. One is a sustained security cleanup, largely driven by external reports and handled release by release. The other is a quiet repositioning of the API: 3.22.0 improved it specifically to support MCP, which points a file-based CMS at agent-driven authoring. The plugin hook work in 3.20.0 fits the same pattern of opening the editor to programmatic control.
Expect the MCP-facing API work to continue — the initial support arrived as API improvements rather than a documented server, which is the piece still missing.

The feed is a content-marketing channel aimed at small businesses and agencies, not a changelog. The ChatGPT guide suggests Metricool wants its analytics data used inside AI assistants for post planning, but the entries never say when or how that connection shipped.
More evergreen guides are near certain; whether Metricool extends the AI-assistant connection beyond Instagram and ChatGPT is unclear from these entries.
