Calibre vs Dovetail: 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 Dovetail?
Dovetail lets admins choose which connectors members can plug into the workspace.
Channels 2.0 reached general availability on October 21. In November Dovetail opened itself to outside assistants: Claude and ChatGPT can co-author docs, agents can be managed from MCP clients such as Claude and Cursor, and Jira roadmap items can pull in Dovetail evidence. On November 12 it added the matching control: workspace admins decide which connectors members may use.

◆ 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.
Dovetail
5.0ANALYTICS
Dovetail lets admins choose which connectors members can plug into the workspace.
◆ Current state
Channels 2.0 reached general availability on October 21. In November Dovetail opened itself to outside assistants: Claude and ChatGPT can co-author docs, agents can be managed from MCP clients such as Claude and Cursor, and Jira roadmap items can pull in Dovetail evidence. On November 12 it added the matching control: workspace admins decide which connectors members may use.
◆ Where it's heading
Dovetail is turning its research repository into a source that other tools and assistants read and write, rather than a place people must visit. The admin connector controls show the cost of that openness: each new integration needs a security gate before larger customers will turn it on.
◆ Prediction
With connectors now gated by admins, expect more connectors and MCP actions to ship behind the same controls, plus audit detail on what connected tools did.
