Calibre vs ThingsBoard: at a glance
What is Calibre?
Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
Calibre now ships a read-only MCP server that gives Claude Code, Cursor, Codex, Copilot, Claude and ChatGPT access to an account's RUM, CrUX and Synthetic data, included on every plan. It came days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0. The latest entry is a design tidy-up that places each page's Guide link in the same top-right spot.
What is ThingsBoard?
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.

◆ Current state
Calibre now ships a read-only MCP server that gives Claude Code, Cursor, Codex, Copilot, Claude and ChatGPT access to an account's RUM, CrUX and Synthetic data, included on every plan. It came days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0. The latest entry is a design tidy-up that places each page's Guide link in the same top-right spot.
◆ Where it's heading
Calibre is turning its monitoring data into something agents act on rather than something people read in dashboards. The summer work on deployment markers, all-pages aggregates and the audit log built the context and governance an agent needs: which deploy, which page, who connected. Expect the remaining surface to follow the same path, with agents both querying performance and being measured by it.
◆ Prediction
The likely next step is write access or deploy-linked workflows over MCP, such as an agent opening a fix tied to a regression marker, since the current server is explicitly read-only and the launch frames fixing as the goal.
ThingsBoard
5.0ANALYTICS
ThingsBoard closes a script-sandbox file write and dozens of CVEs on its 4.3 and 4.2 lines.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
