Do you need an account

No: the server works without sign-in

The GEO check every vibe coder runs before they launch.

Synapse is the GEO (Generative Engine Optimization) growth layer for new products. This MCP server gives any coding agent — Cursor, Claude Code, Windsurf, Cline, Continue, Zed — the ability to audit, fix, and track how AI agents discover and recommend a project.

Tools

  • geo_check — Run the 24-rule GEO linter on a URL or local path. Returns a 0–100 Growth Score and a list of failing rules with evidence.
  • geo_fix — Apply auto-fixers: writes llms.txt, robots.txt (with the AI-bot allowlist), and /.well-known/agent-answer.json to the project. Never touches your content.
  • geo_track_init — Register the site with the Synapse dashboard to start tracking AI-agent referrals.
  • geo_prompts — Generate a visibility-test prompt pack for ChatGPT / Claude / Perplexity.
  • geo_status — Live Growth Score, agent mentions, and visits for an installed site.
  • geo_corpus_query — Query the public Synapse corpus to find products matching a user intent.

Resources

  • synapse://docs/llms-txt-spec — the canonical llms.txt reference
  • synapse://docs/geo-checklist — the full 24-rule rubric
  • synapse://corpus/latest — recent agent-recommendation tuples
