Reading the table

  • Governed AI (per the tool notes): Lightdash and Hex describe agents answering from a semantic layer of defined metrics; Metabase documents permission-scoped MCP/Metabot, and Preset describes RBAC for its MCP.
  • Developer-first: Evidence and Lightdash keep analytics as files in git.
  • Time-series and ops dashboards: Grafana, not a business-metrics tool.
  • Legacy (author’s characterisation): the Redash note describes mostly maintenance/security releases; no formal maintenance status was verified and the GitHub page shows no archived flag.
  • Not to confuse: Superset coding orchestrator.
  • Related: looker-studio, business-intelligence.

Open items

  • Verified 2026-10-07 against primary pages: licences of Metabase (AGPL plus commercial enterprise directory), Superset (Apache 2.0), Lightdash (MIT with ee carve-out), Evidence (MIT), Redash (BSD-style licence file), Grafana (AGPL-3.0), mcp-grafana (Apache 2.0); Metabase built-in MCP server with its own OAuth 2.0 (docs, v0.64); Lightdash AI agents GA as a paid add-on with content-editing and coding-agent parts in beta, and an MCP server.
  • Not confirmed: Superset 6.1 MCP service (the 6.1.0 GitHub release text, dated 13 May, does not mention it; the vault note relies on Preset posts), Preset MCP Enterprise-only and 2026-04-01 launch (docs URL 404), Metabot per-edition availability, Hex and Grafana Assistant claims, Evidence MCP, Redash being in “maintenance mode” as a formal status.
  • Redash licence: LICENSE file is BSD-style (Arik Fraimovich); the specific “2-Clause” label was not checked.
