Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

BACKLNK runs evidence-based technical SEO and AI-visibility checks on public web pages and reports what it measured. Work in a loop: (1) run_checks on the page's public URL: you get the issues and warnings, most important first, each with evidence and a recommendation. (2) Fix them in the codebase, starting with the first findings. Changes are only visible to the checks once they are deployed to that public URL. (3) verify_fixes with each audit_id: it re-runs the same check fresh and reports what is fixed, new, still open or not re-checked. Use get_report for the report of an earlier check (detail: "all" for every finding), list_checks for all check ids, ai_crawler_policy for robots.txt rules for AI crawlers and usage for the key's remaining quota. Status NotAssessed means the check could not determine the result: do not treat it as a pass. Only Issue and Warning findings need action.

list_checks — List BACKLNK checks
Advertised by the server during the last successful anonymous check.
Advertised read-only

Lists every check BACKLNK can run (id, what it looks at, its scope and limits). Use the ids with run_checks.

run_checks — Check a page
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Runs BACKLNK checks on one public URL and waits up to about 40 seconds. Returns, per check, its state, summary, counts and the issues and warnings to fix (most important first, with evidence and a recommendation), plus the audit ids for get_report and verify_fixes. Default checks: meta-tags, page-structure, ai-crawler-access, redirects-headers, entity-schema.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
