Sendible is steadily hardening publishing reliability and reporting accuracy across networks
Sendible's changelog is genuine product work focused on two areas: making publishing more reliable (rebuilt media infrastructure, universal media validation) and improving cross-network reporting (Facebook Reels analytics, corrected LinkedIn follower data). Recent additions include image alt text for accessibility and a redesigned Unified Calendar for managing drafts, scheduled posts, and queues in one view. The feed shows some duplicate entries for the same feature on different dates.
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.

The direction is operational dependability for social-media managers — fewer failed posts, accurate analytics, and a single workspace for scheduling. Sendible is deepening the core publish-and-measure loop rather than chasing new surfaces. Accessibility (alt text) and unified scheduling suggest attention to workflow polish on top of the reliability foundation.
Expect continued reporting-accuracy work across more networks and further consolidation of the scheduling/calendar experience, with reliability remaining the throughline.

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.
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.
