--- id: integrations/openseo-a-plugin-candidate title: 'OpenSEO — a strong plugin candidate, checked rather than assumed' theme: integrations status: open created: 2026-08-27 date_source: stated order: 1 --- **OpenSEO (`every-app/open-seo`) — worth building a plugin around.** Asked to be evaluated 2026-08-27; checked against gitea rather than taken on the README's word. **What it is:** a self-hosted, open-source alternative to Semrush/Ahrefs — keyword research, rank tracking, competitor insights, backlinks, site audits, AI visibility. MIT licensed, TypeScript, **14.4k stars, 1.7k forks, pushed 3 days ago** (verified via `gh repo view`, not the README's own framing) — a real, active project, not an abandoned demo. **Why it fits this platform specifically, more than most tools would:** it ships **its own MCP server and Agent Skills**, built explicitly to be driven by "Claude Code, OpenClaw, or Hermes." That is Officer's whole plugin thesis already built by someone else — most candidates need Officer to invent the agent-facing surface; this one already has one. **The self-hosting shape is the easy case, verified from `compose.yaml` and the docs, not assumed:** - **One container, no separate database.** Cloudflare D1 (SQLite) by default — Postgres is opt-in only for installs that outgrow it (`docs/LOCAL_POSTGRES.md`). Same shape as Jellyfin, Gitea, Transmission: a single sidecar, nothing extra to provision. - **One required credential**: a DataForSEO API key, paid pay-as-you-go DIRECTLY to DataForSEO — not a subscription to OpenSEO itself unless using their hosted version. Two more are optional (OpenRouter for its own AI features, Google OAuth for Search Console). Real cost, worth saying plainly: this is free software over a metered API, not a free service. - **Self-hosting runs `AUTH_MODE=local_noauth` by design** — their own docs say explicitly _"only expose it behind your own auth-protected reverse proxy, tunnel, or private network."_ That sentence describes exactly what an Officer plugin already is: mounted behind Officer's own permission gate, never exposed on its own. This is the ordinary case for a plugin here, not a special risk to design around. **What a plugin would actually need to add, and it may be less than usual:** because OpenSEO already runs its own MCP server, the plugin's job is closer to credential plumbing and a UI surface (`osDependencies`-style container/sidecar, the DataForSEO key in the per-user/server credential store, a panel embedding or proxying its web UI) than inventing new MCP tools from scratch — most of the agent-facing work is already done upstream. Open, for whoever picks this up: whether Officer's agents call OpenSEO's own MCP endpoint directly (simplest, if reachable over whatever network the plugin runs on) or Officer wraps it as Officer-native MCP tools for consistency with how other plugins expose theirs; and where the container runs given `todo/infra/opm-officer-s-own-process-manager` is heading toward the Docker network specifically so container-backed dependencies like this one need no published host port.
