Open-source SEO content software: audits, keywords, Search Console, drafts
About
AltoRank is open-source SEO content software (AGPL-3.0). Its hosted MCP server (Streamable HTTP, OAuth) gives an agent 26 tools:
- Nine readiness checks against any public domain (AI-crawler rules, sitemaps, structured data, machine-readable content) - Keyword suggestions based on what a site's buyers search for, and moving the content plan - Google Search Console performance, coverage, cannibalization and URL inspection - Drafts in the site's voice with sources attached and a fact check, which land in a person's review queue
There is no approve, publish or delete tool: every publish is attributed to a named person, by a click or by a rule they set. The account tools need an AltoRank workspace (self-host free, or hosted from €69/month with a 7-day trial). Also in the official MCP registry as co.altorank/altorank.
Security Report
AltoRank is an open-source, self-hosted AI SEO content writer whose MCP server and agent API are designed so agents can research and draft but cannot approve or publish articles; the code shown is largely documentation and package manifests, so the analysis is limited to what was provided. Permissions (network_http for DataForSEO, Supabase, CMS adapters, and env_vars for API keys) match the stated purpose and the Marketing & Social category baseline, and no hardcoded secrets or malicious patterns were visible in the excerpts. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 1 high severity).
