Calibre vs Shynet: 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 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 Shynet?
Shynet went silent for two and a half years and a security audit is what woke it up.
Shynet's most recent release closes two externally reported vulnerabilities: a wildcard ALLOWED_HOSTS default enabling password reset poisoning, and stored XSS in two template filters, both credited to an outside security firm. It arrived after a gap of roughly two and a half years, and the release before it was a temporary dependency install workaround. The dashboard features people associate with the project — the annotated world map, the map-versus-table toggle — all date from 2021.

◆ 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.
Shynet
0.0ANALYTICS
Shynet went silent for two and a half years and a security audit is what woke it up.
◆ Current state
Shynet's most recent release closes two externally reported vulnerabilities: a wildcard ALLOWED_HOSTS default enabling password reset poisoning, and stored XSS in two template filters, both credited to an outside security firm. It arrived after a gap of roughly two and a half years, and the release before it was a temporary dependency install workaround. The dashboard features people associate with the project — the annotated world map, the map-versus-table toggle — all date from 2021.
◆ Where it's heading
The arc is a project that had real community momentum and then stopped. In 2021 releases were arriving monthly and were, by the maintainer's own note, driven entirely by contributors; by 2023 the content was dependabot bumps and build workarounds; after that, nothing until a security report forced a response. Nothing in the recent entry suggests development resumed more broadly — it is a targeted fix release, not a return to cadence.
◆ Prediction
These entries give no basis for expecting feature work to resume; the realistic expectation is that the next release, whenever it comes, is again driven by an external security report or a dependency that stops installing.
