How to install synapse

npx -y synapse-os                      # no args → stdio MCP server (existing configs keep working)
npx -y synapse-os mcp                  # explicit MCP mode

Taken from the project's README on GitHub. Check the security audit before running it.

Security audit verdict: SAFE · quality 65/100

None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours. Full audit →

The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

About synapse

Synapse — Personal AI Memory OS Chat history is a log. Synapse is a brain. Synapse is a local-first personal memory operating system that gives AI agents durable, typed long-term memory. It extracts semantic facts from episodic conversations, anchors single-current-value facts to entity keys so new values supersede old ones, detects and resolves conflicts, decays stale information, and retrieves...

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
