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 Deepnote?
Deepnote's agent now runs from first prompt to finished notebook without handoffs.
Deepnote's most recent entry, in October, makes Deepnote Agent a single agent that keeps context from the first instruction to the finished notebook, and lets private and shared projects sit in the same folder. It builds on June's native Codex connection to a workspace's notebooks, schedules and data, and July's MCP tools that let agents create and attach integrations. Spring releases added run snapshots, Git sync, Polars support, PDF export and AI usage metering.

Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
◆ 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.
Deepnote
2.5ANALYTICS
Deepnote's agent now runs from first prompt to finished notebook without handoffs.
◆ Current state
Deepnote's most recent entry, in October, makes Deepnote Agent a single agent that keeps context from the first instruction to the finished notebook, and lets private and shared projects sit in the same folder. It builds on June's native Codex connection to a workspace's notebooks, schedules and data, and July's MCP tools that let agents create and attach integrations. Spring releases added run snapshots, Git sync, Polars support, PDF export and AI usage metering.
◆ Where it's heading
The notebook is being repositioned as a workspace agents operate in, both Deepnote's own agent and external ones like Codex. Releases have slowed from monthly in spring to one entry each in July and October.
◆ Prediction
Further agent capabilities or more external agent connections are the likeliest next move; the slower cadence makes timing hard to read.
