What is Sanity?

Sanity's MCP server now explains failed validations and stops skipping them.

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

What is Stirling-PDF?

Stirling PDF plans to drop LibreOffice for its own converter within two weeks

Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.

6.3

Sanity's MCP server now explains failed validations and stops skipping them.

◆ Current state

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

◆ Where it's heading

Sanity is making the agent-facing parts dependable: the MCP server is getting the error codes and validation rules a production client needs. Access visibility for tokens and members follows the same push to let teams audit what automated clients do.

◆ Prediction

Expect more MCP server point releases around validation and Knowledge Base commands, and more usage data on tokens and agents in the console.

S5.0

Stirling PDF plans to drop LibreOffice for its own converter within two weeks

◆ Current state

Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.

◆ Where it's heading

The project is replacing third-party dependencies with its own components. 3.3.0 says Office Convert should become the default next week and LibreOffice should be removed the week after, which would shrink the install and change conversion results for every user.

◆ Prediction

Expect Office Convert to become the default converter in the next release, then LibreOffice removed, as 3.3.0's notes lay out. Conversion bug reports will decide whether that schedule holds.
