What is Bludit?
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.
What is Surfer SEO?
Surfer shipped the MCP server its May API release said it was building toward
Surfer has spent 2026 collapsing the distinction between ranking on Google and being cited by AI models, and the last month completes the delivery path it laid out in May. The API rebuild was described at the time as the foundation for an MCP server; that server is now in beta, exposing the Content Editor lifecycle, Auto-Optimize, SEO and AI Search guidelines, AI Tracker visibility data and Recommendations as tools an agent can call. Alongside it, Recommendations began consuming AI Tracker signals to prioritise which mentions to earn and which sentiment to fix.

A flat-file CMS with a long CVE history just wired its API up for MCP.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.

Surfer shipped the MCP server its May API release said it was building toward
◆ Current state
Surfer has spent 2026 collapsing the distinction between ranking on Google and being cited by AI models, and the last month completes the delivery path it laid out in May. The API rebuild was described at the time as the foundation for an MCP server; that server is now in beta, exposing the Content Editor lifecycle, Auto-Optimize, SEO and AI Search guidelines, AI Tracker visibility data and Recommendations as tools an agent can call. Alongside it, Recommendations began consuming AI Tracker signals to prioritise which mentions to earn and which sentiment to fix.
◆ Where it's heading
The direction is Surfer as a capability an agent uses rather than an application a writer opens. Everything shipped since May points that way: the API first, then the agent interface, with the scoring and guideline logic being the part that stays proprietary. The AI Tracker work suggests the second front is measurement — owning the data on whether models cite you, which is what makes the recommendations worth calling in the first place.
◆ Prediction
Expect the MCP beta to move to general availability with the Agentic Surfy work the May release named, and for AI Tracker data to keep spreading into the surfaces that already existed.
