Searchlight

Technical SEO that fixes itself.

An autonomous technical-SEO and analytics agent, delivered as a Model Context Protocol (MCP) server. Point it at your site: it finds what's broken, explains it in plain language, fixes it in your repository, deploys, and verifies the fix is live.

The loop

Most SEO tools stop at the diagnosis. Searchlight runs the whole loop and proves the last step.

Proof

A live run on zawaaj.in (a custom Next.js site with a host and canonical conflict and missing analytics) went from audit 90 → 98 — canonical set, host redirect aligned (www → apex), meta trimmed, GA4 installed and verified firing, sitemap submitted — in about 50 minutes (≈25 minutes active; the rest idle waiting on a redeploy), versus a 4–6 hour manual baseline for a skilled developer. The full annotated run is on the website.

Searchlight automates the diagnosis and the fix. It does not design your ecommerce event-tracking plan — that part is still a human's job.

Quickstart

1. Add it to your MCP client (Claude Code shown; works in any MCP client):

claude mcp add searchlight -- npx -y @ajmalaksar/searchlight serve --setup

Or, in a generic client config:

{
  "mcpServers": {
    "searchlight": { "command": "npx", "args": ["-y", "@ajmalaksar/searchlight", "serve"] }
  }
}

2. Sign in with Google (one local OAuth sign-in for Search Console and Analytics; the token is stored only on your machine):

npx -y @ajmalaksar/searchlight login --setup

3. Install the /searchlight skill so your agent runs the whole loop with one command:

npx -y @ajmalaksar/searchlight skill install

4. Ask:

/searchlight audit zawaaj.in

First time on Google Cloud? The bundled client lets most users skip setup. To bring your own (Tier 0), create a Desktop app OAuth client (enable the Google Search Console API and PageSpeed Insights API, add yourself as a test user) and pass SEARCHLIGHT_OAUTH_CLIENT_ID / SEARCHLIGHT_OAUTH_CLIENT_SECRET to login.

Renamed from gsc-mcp: the legacy ~/.gsc-mcp directory and GSC_* environment variables still resolve, so an existing install keeps working without re-authenticating.

The /searchlight skill

skill install drops a skill into your AI client so the agent orchestrates the full loop instead of you calling raw tools. It routes on the first word:

It always confirms before any provisioning, code edit, sitemap submit, or deploy.

Tools

auth_status, auth_login, list_sites, use_site, get_active_site, set_default_site, account_overview, gsc_deep_link, query_search_analytics (presets: top_queries/top_pages), find_opportunities, compare_periods, inspect_url, coverage_report, refresh_coverage, crawl_site, site_audit, export_report, diagnose_site, audit_page, page_speed, snapshot_baseline, list_snapshots, progress_report, ga_list_properties, ga_measurement_id, ga_report (presets: traffic/top_pages), list_sitemaps. With --write / --setup: submit_sitemap, delete_sitemap, and the GA4 / verification provisioning tools.

crawl_site → site_audit → export_report crawl your live site directly (no Google scope, no quota), then produce a triaged, site-wide technical-SEO report (status/redirects/ canonicals/orphans/link-graph/schema/hreflang) you can share as Markdown.

Coverage report reconstructs the "Page indexing" report the GSC API won't export in bulk: it gathers candidate URLs from sitemaps and analytics, inspects them within the 2,000/day per-property quota (resumable), caches the results under ~/.searchlight/sites/, and buckets them by index status.

Baseline & progress (snapshot_baseline → … fix … → snapshot_baseline → progress_report) freeze a site's health on a given day, then diff two days into a plain-English before→after of what improved — which issues resolved, which are new, and how score and traffic moved.

Local-first & private

Searchlight runs as a local server. You sign in with your own Google account; the token is stored only on your device. There is no hosted backend and no data warehouse — each person runs their own. Read-only by default; write and provisioning scopes are opt-in, requested only when you start a setup action. Open source and MIT licensed. See the Privacy Policy.

CLI

searchlight login            Sign in with Google (opens a browser)
searchlight logout           Remove the stored token
searchlight status           Authentication + onboarding status
searchlight setup            Guided first-run
searchlight sites …          Manage the property registry (list / add / remove / default)
searchlight skill install    Install the /searchlight skill into your AI client (--here for this project)
searchlight serve            Start the MCP server over stdio (default)

Develop

npm install
npm run build
npm test

The server is a tool registry. To add a capability, create src/tools/<group>.ts exporting register: ToolModule, then add it to MODULES in src/tools/index.ts. See SPEC.md for the architecture.
