Calibre vs Apache Storm: 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 Apache Storm?
Storm 3.1 adds an Iceberg sink and closes a long list of security gaps in Nimbus and the UI.
Storm runs a 3.x line, started in July with 3.0.0's removal of all Clojure and a Java 21 baseline, alongside 2.8.x maintenance. 3.1.0 on September 12 adds a storm-iceberg module with an Apache Iceberg sink bolt and a setting to control JSONP wrapping, and spends most of its notes on hardening: log listings filtered by user permission, jar locations restricted to the Nimbus inbox, blobstore names confined to topology directories, TLS peer verification for worker connections and required Kryo class registration.

◆ 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.
Apache Storm
0.0ANALYTICS
Storm 3.1 adds an Iceberg sink and closes a long list of security gaps in Nimbus and the UI.
◆ Current state
Storm runs a 3.x line, started in July with 3.0.0's removal of all Clojure and a Java 21 baseline, alongside 2.8.x maintenance. 3.1.0 on September 12 adds a storm-iceberg module with an Apache Iceberg sink bolt and a setting to control JSONP wrapping, and spends most of its notes on hardening: log listings filtered by user permission, jar locations restricted to the Nimbus inbox, blobstore names confined to topology directories, TLS peer verification for worker connections and required Kryo class registration.
◆ Where it's heading
After the 2.8.6 and 2.8.7 CVE releases, the 3.x line is closing access-control gaps across Nimbus, the logviewer and worker transport. The Iceberg sink adds a direct path into lakehouse storage.
◆ Prediction
Expect 3.1.x follow-ups, possibly with security advisories for the hardened paths, and continued 2.8.x maintenance; whether more lakehouse connectors follow is unclear.
