Fulcrum lets AI assistants sign in to its MCP server with a normal account.
Fulcrum, a field data collection platform, opened its Insights AI assistant to all customers in October. Its weekly web release now adds OAuth sign-in for the Fulcrum MCP server in alpha, so outside AI assistants connect with a user account and see only what that role allows. The rest is GPS Device Capture support on repeatables and fixes across the web, iOS and Android apps.
ThingsBoard closes a script-sandbox file write and dozens of CVEs on its 4.3 and 4.2 lines.
ThingsBoard keeps three lines patched in parallel: 4.4, 4.3.1 and the 4.2 LTS. On October 27, 4.3.1.8 and 4.2.2.8 shipped a large security batch, including a fix for arbitrary file writes from the TBEL script sandbox and tamper protection for the OAuth2 authorization cookie. On October 30, 4.4.0.2 followed with security patches, though its notes list no details.

The rest is GPS Device Capture support on repeatables and fixes across the web, iOS and Android apps.
Fulcrum is opening its data to AI from both sides: Insights inside the product and MCP for assistants outside it. Role-scoped OAuth is the piece that makes the outside route usable without sharing API tokens.
The MCP sign-in is likely to move from alpha to beta in the weekly web notes, following how Insights and GPS Integration were labeled as they matured.

On October 30, 4.4.0.2 followed with security patches, though its notes list no details.
After the 4.4 feature release the project is back to maintenance on all supported lines, mostly security and runtime fixes, with the IoT Hub catalogue getting steady UI work alongside. Feature work arrives in larger, infrequent releases.
Expect the next entries to be routine patches across all three lines. The notes do not say whether 4.4.0.2 carries the same fixes as the 4.3 batch.
