AltoRank

AltoRank (https://altorank.co) is open-source SEO content software. Its tools come from the altorank MCP server. You can audit whether search engines and AI assistants can read a site, read an account, create drafts, move planned keywords, edit a draft by find-and-replace, and pause or resume a workspace. A person decides what publishes. There is no approve, hold or delete tool and no tool that publishes a draft, and you must not look for a way around that. The one publish-side tool, altorank_retry_publish, only re-runs a failed publish of an article a person already approved.

When to Use

• Use when the user asks about SEO or AI-search (GEO) readiness of a site, Search Console numbers, keyword research, or drafting articles for their site with AltoRank.
• Use when the user wants missing JSON-LD proposed for a page, or a readiness report for any public domain.
• Requires an AltoRank account (hosted, or a self-hosted install) and the altorank MCP server connected.

Connect once

If the altorank tools are missing, tell the user:

• Claude Code: claude mcp add --transport http altorank https://app.altorank.co/api/mcp, then /mcp → altorank → Authenticate (OAuth in the browser)
• Claude Code plugin (bundles this skill and the server): claude plugin marketplace add AltoRank/altorank, then claude plugin install altorank@altorank
• Other MCP clients: add a Streamable HTTP server at https://app.altorank.co/api/mcp and sign in with OAuth. Self-hosted installs use their own origin.

Two kinds of tools

• Any domain: altorank_check_readiness, altorank_propose_schema, altorank_generate_machine_readable, altorank_readiness_report. Work on any public domain, not only the person's own sites.
• Workspace tools: everything else. They act on the person's AltoRank account. Write access is opt-in on the OAuth consent screen; a forbidden error means they did not grant it. unauthorized means the connection expired and the person has to reconnect.

Reading results

Every tool returns { ok, data | error, agent_guidance }.

• Read agent_guidance first. It is written for you.
• _human, when present, is how to describe a record to a person. Use its labels, not raw field names or enum values.
• Articles and keywords carry allowed_mutations. If a verb is allowed: false, tell the person the reason and do not retry.
• Articles carry editor_url. That is the link you give a person.
• null means unknown or unmeasured. Say "unknown", never 0.

Preflight

1. altorank_whoami: confirms the connection, lists workspaces and quota.
2. One workspace: use it. Several: ask which, unless the conversation says.
3. altorank_get_workspace: no CMS connected means the person publishes by hand.
4. altorank_readiness_report: if the score is low, fixing readiness comes before writing more content.

Writing a draft

1. altorank_list_keywords. Prefer a keyword whose allowed_mutations.generate_draft.allowed is true.
2. Nothing fits: altorank_suggest_keywords. It spends research credits, so ask first. Results are candidates, not saved.
3. Agree the keyword (and optionally a title) with the person.
4. altorank_generate_draft with one idempotency_key per intended draft. Nothing is published.
5. Poll altorank_get_article every 30-60 seconds until status is review (about two minutes). error means the run failed; generation says why.
6. Tell the person the draft is ready at its editor_url, then stop.

A timeout is not a failure: the draft has usually started. Repeat the call with the same idempotency_key, never a fresh one.

Changes (need write access)

Always inspect, propose, confirm, then write.

• altorank_replace_in_article / altorank_bulk_replace_in_articles: the first call is a preview. Show the hits, get a yes, then apply. Approved, scheduled and live articles are refused.
• altorank_reschedule_keywords, altorank_remove_keywords_from_plan: only unwritten planned entries move. Removing keeps the keyword tracked.
• altorank_retry_publish: only when allowed_mutations.retry_publish.allowed is true (approved, then the publish failed). Tell the person first.
• altorank_pause_workspace / altorank_resume_workspace: pause stops drafting and publishing; resume re-plans from today.

Search Console

altorank_gsc_performance, altorank_gsc_cannibalization, altorank_gsc_coverage and altorank_gsc_url_inspection read stored data; nothing calls Google. Keep these states apart:

• not_available: Search Console is not connected, Google refused the stored token (a person reconnects), or no sync has succeeded (relay the error in agent_guidance). No data; do not say "no traffic".
• has_data: false: connected, nothing synced for the window. Never report 0.
• has_data: true with zeros: Google measured nothing. The site is not being shown in search.
