Rankrat

rankrat

[CI] [coverage] [version] [license] [Docker Pulls]

Every SEO signal lives in its own walled garden with its own dashboard, its own API, and its own bullshit auth dance: Search Console over here, GA4 over there, Bing Webmaster somewhere else, plus Cloudflare, Clarity, PageSpeed, CrUX, GTM, and Bing's backlink data. Point an agent at your rankings and it drowns juggling eight consoles. Rankrat drags all of them behind one self-hosted service, so you tell an agent the outcome you want and it inspects, creates, updates, or rips out provider resources through a single surface — REST and MCP, no dashboards.

It's a rat, not a burglar. You hand it the provider accounts; those credentials are the only authority it has. The resource lists in boundaries.json are inventory and URL-containment data — not a second permission system pretending to keep you safe. Rankrat writes by default; set RANKRAT_READ_ONLY=true and every mutating route and tool disappears from discovery. That's the one switch.

It speaks MCP over stdio, MCP over Streamable HTTP at /mcp, and a FastAPI JSON API under /v1/. Wrapper-managed HTTP gets a bearer; a hand-rolled loopback-only launch can drop it if you know what you're doing.

Status: alpha. The API and tool surface can still move before 1.0 — minor releases may break things on purpose (documented), so pin an exact release if you need it to hold still.

Capabilities

What the runtime advertises is what it does — no hidden endpoints. A read-only deployment drops every write from discovery; a writable one exposes onboarding alongside the rest. The whole list is the MCP tool catalog and the generated OpenAPI document.

Quick start

Install the rankrat command, create the credentials for the providers you want, then run it. Docker is the only runtime requirement.

Install

Download the installer, read it, then run it — per-user (no root) or system-wide:

curl -fsSL https://raw.githubusercontent.com/psyb0t/rankrat/main/install.sh -o rankrat-install.shless rankrat-install.shbash rankrat-install.sh                # per-user   -> ~/.local/bin/rankratsudo bash rankrat-install.sh --system  # system-wide -> /usr/local/bin/rankrat

The mode auto-detects from who runs it; --user / --system force it and --uninstall removes the command. This puts the rankrat wrapper — a readable script that drives the published Docker images — on your PATH. Prefer to work from a source checkout? Clone the repo and use ./rankrat or the make targets instead; see Getting started.

Set up

Run setup. It lists every provider, you pick the ones you actually use, and it walks you through creating each credential — the exact console clicks for Google OAuth, the Bing Webmaster key, the Cloudflare token, the Clarity token — then hides every value you paste. No copying token permissions out of a README:

rankrat setup

Configuring Google? Paste the one-line Desktop OAuth client JSON at the hidden prompt when setup asks — same as every other credential.

Setup validates account access — it does not submit URLs or create properties. Your profile lives in ~/.config/rankrat; override it per launch with rankrat --data-dir /absolute/path or RANKRAT_DATA_DIR for a separate profile per account or workspace. Want to read the credential steps ahead of time, or what each provider actually gives you? See Providers and credentials. From a source checkout the setup step is make setup.

Run it

rankrat            # MCP over stdio (default)rankrat http -d    # REST + Streamable-HTTP MCP + Lighthouse, detached with restartsrankrat upgrade    # re-pin to the latest release, pull it, drop the previous image

From a source checkout: make run (stdio) and make run-http (HTTP over Compose, attached).

rankrat setup pins both psyb0t/rankrat and psyb0t/rankrat-lighthouse to the latest release tag — recorded, along with the HTTP port and read-only flag, in a .env at your profile root — rather than tracking the moving :latest. rankrat upgrade re-pins the images to the newest release, pulls both, restarts a running HTTP stack (reusing the recorded port and read-only flag), and removes the superseded images; it leaves the port and read-only lines untouched. Pass --rolling (or set RANKRAT_ROLLING=1) to use the moving :latest images for a single run without touching the recorded pin. RANKRAT_IMAGE, RANKRAT_LIGHTHOUSE_IMAGE, RANKRAT_HTTP_PORT, and RANKRAT_READ_ONLY still override the recorded values per run.

To set the host settings once instead of per run, put them in a permanent host env file at ~/.config/rankrat/.env (override the path with RANKRAT_ENV_FILE). The wrapper reads it before selecting a profile, so it can set RANKRAT_DATA_DIR (which profile to use) along with RANKRAT_READ_ONLY, RANKRAT_IMAGE, RANKRAT_LIGHTHOUSE_IMAGE, RANKRAT_HTTP_PORT, RANKRAT_OAUTH_CALLBACK_PORT, and RANKRAT_ROLLING. It only fills a variable that is unset or empty, so a --data-dir flag or a real env var still overrides it. This is especially handy for MCP launchers that run rankrat with a minimal environment and never see your shell exports. It is separate from the per-profile .env: the host file selects the profile and the host defaults, while a profile's .env pins that profile's images, port, and read-only flag.

Over HTTP, MCP lives at http://127.0.0.1:8080/mcp and REST under /v1/; stdio needs no port and no bearer. HTTP treats your data directory as its Compose project — it drops a docker-compose.yml in there if one's missing and never touches yours if it isn't. Under the hood that's two long-lived services plus one one-shot volume initializer. The wrapper, plain docker run, raw Compose, HTTP auth, and client wiring all live in Transports and deployment.

Browser audits run in a separate psyb0t/rankrat-lighthouse image over a Unix socket, and it never sees a single provider credential. rankrat stdio brings up an ephemeral Lighthouse sidecar for the session — same capability as HTTP — and tears it down on exit; the wrapper launches it host-side, so the app stays off the Docker socket and reaches Lighthouse only over the socket. See Lighthouse.

Safety model

• Rankrat is writable by default. Configured account credentials authorize all supported provider operations and all resources those accounts can reach.
• RANKRAT_READ_ONLY=true removes write REST routes and MCP tools from runtime discovery. It is the only capability switch.
• The operator decides whether the caller is a careful human-directed agent or a fully autonomous one. Remote HTTP still uses the configured bearer.
• Resource arrays are cached inventory and containment data. Onboarding and discovery update them so retries reuse existing resources.
• Secrets are read-only mounts; OAuth records and monitor state have separate writable mounts.

See Configuration and Security before enabling writes or exposing HTTP beyond loopback.

The REST source is YAML-first: openapi.yaml, seo-openapi.yaml, and free-seo-openapi.yaml generate openapi.json. Agent clients can use the repository's skill, Claude Code and Codex manifests, or OpenClaw integration under .agents.

Agent integrations

The Rankrat skill works in agents that read .agents/skills/ (such as peen). The integrations below cover both MCP stdio and a shared Streamable HTTP server.

Claude Code

claude plugin marketplace add psyb0t/agentsclaude plugin install rankrat@psyb0t

Codex

codex plugin marketplace add psyb0t/agentscodex plugin add rankrat@psyb0t

Installed through the catalog, the skill invokes as $rankrat:rankrat. Codex also discovers it as $rankrat directly from a Rankrat checkout.

OpenClaw

openclaw skills install @psyb0t/rankratopenclaw plugins install clawhub:@psyb0t/rankrat

The plugin launches the published image over MCP stdio using the standard $HOME/.config/rankrat/ layout. Set one absolute RANKRAT_DATA_DIR in every client to reuse the same provider accounts, OAuth authorization, inventory, and monitor state from any site repository. To use an already-running shared server, configure OpenClaw for its authenticated http://127.0.0.1:8080/mcp Streamable HTTP endpoint. See Transports.

Development

Everything runs in containers — no "works on my machine" roulette:

make helpmake lintmake test

Mocked tests need zero credentials. Live tests are opt-in and pull their one account plus a safe target straight from your profile, so they can't wander off and touch something they shouldn't. Full contributor guide in Development.
