The Statsig plugin currently connects to
/v1/mcp. Switch it tohttps://api.statsig.com/v3/mcpfor the v3 rollout and bump the plugin to 2.0.0 because v3 changes tool names and input schemas.Update the README and changelog with tool discovery and migration guidance: reconnect after upgrading, start a new chat to refresh the catalog, and sign in again if prompted. Manually configured connections require a separate update. Preserve the plugin/server identifiers and OAuth HTTP transport.
Validation:
node scripts/validate-plugins.mjspassed for all plugins.git diff --checkpassed.Release prerequisite: confirm v3 is enabled for all companies receiving the public plugin update before publishing. Keep v1 available for older and manually configured clients. This PR changes the Cursor package only; the separate Statsig skills update is statsig-io/agent-skills#3.
Note
Medium Risk
Major-version plugin bump changes the live MCP tool surface users rely on; mis-timed rollout or stale manual v1 configs could break Statsig agent workflows until reconnect/migration.
Overview
Bumps the Statsig Cursor plugin to 2.0.0 and points the packaged OAuth HTTP MCP server at
https://api.statsig.com/v3/mcpinstead of/v1/mcp(mcp.json, README example, docs link).Documentation now covers MCP v3 breaking changes (renamed tools and input schemas): reconnect after upgrade, start a new chat to refresh the tool catalog, re-auth if prompted, and separately update any manual MCP entries to avoid duplicate connections. The README also steers agents toward the advertised tool list and
discover_toolsfor hidden capabilities, and generalizes write guidance away from legacyUpdate_*_Entirelytool names.Reviewed by Cursor Bugbot for commit 742e96e. Bugbot is set up for automated code reviews on this repo. Configure here.
