synapse-geo — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited synapse-geo (MCP Server) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

npx synapse checkSynapse is a CLI + MCP server + linter that makes a new product discoverable and recommendable by AI coding agents (Cursor, Claude Code, Windsurf, v0, Bolt, Lovable). Run synapse check against a project path or URL and get a 0–100 Growth Score plus a list of failing rules and one-command auto-fixes.
| Package | Description |
|---|---|
@synapse/geo-lint | 24-rule GEO linter. Programmatic API: lint(target) → LintReport. |
@synapse/cli | CLI with init, check, fix, deploy, status. Installs as synapse. |
synapse | Thin meta-wrapper for the npx synapse UX. |
@synapse/mcp-server | MCP server exposing 6 tools, 3 resources, 3 prompts. Stdio + streamable HTTP. |
# In a fresh project:
npx @synapse/cli init # scaffolds synapse.config.json + tracker stub
npx @synapse/cli check # 24-rule lint, prints scored report
npx @synapse/cli fix # apply auto-fixes (llms.txt, robots.txt, agent-answer)
# With an account:
export SYNAPSE_API_KEY=…
npx @synapse/cli deploy # register the site, get a /s/<slug> dashboard
npx @synapse/cli status # live agent-mention statsSynapse runs as an MCP server so any agent can call geo_check, geo_fix, geo_track_init, geo_prompts, geo_status, and geo_corpus_query directly during a build session.
