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 with nothing to install. It lands days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0, which added audits for how AI agents read pages. Admins can disable MCP per organisation and revoke connections, and the Company-plan audit log records them.
What is Usermaven?
Usermaven is rebuilding analytics around Maven AI agents that report without being asked.
Usermaven shipped Maven AI Agents in September, which run scheduled analyses and surface insights proactively, and now lets users save AI-generated charts to dashboards and share agent reports by public link. Over the summer it added an MCP server, a Salesforce integration with reverse ETL, and Event Sources for importing conversions from other tools.

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 with nothing to install. It lands days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0, which added audits for how AI agents read pages. Admins can disable MCP per organisation and revoke connections, and the Company-plan audit log records them.
◆ 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.
Usermaven
2.5ANALYTICS
Usermaven is rebuilding analytics around Maven AI agents that report without being asked.
◆ Current state
Usermaven shipped Maven AI Agents in September, which run scheduled analyses and surface insights proactively, and now lets users save AI-generated charts to dashboards and share agent reports by public link. Over the summer it added an MCP server, a Salesforce integration with reverse ETL, and Event Sources for importing conversions from other tools.
◆ Where it's heading
The product is moving from a web analytics dashboard to a data layer that AI agents query and act on, with data flowing in from CRMs and payment tools and back out to operational tools. Recent releases tie agent output back into the classic dashboard.
◆ Prediction
Expect deeper agent actions, such as alerts or audience syncs triggered from agent findings, building on the agents and reverse ETL already shipped.
