Synapbus — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Synapbus (Agent Skill) and scored it 83/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 4 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

The text {match} tells the agent to skip the normal "ask the user first" gate. Used adversarially it removes the human-in-the-loop check before destructive or sensitive actions, turning a normally-gated agent into a fire-and-forget executor.
The text {match} tells the agent to skip the normal "ask the user first" gate. Used adversarially it removes the human-in-the-loop check before destructive or sensitive actions, turning a normally-gated agent into a fire-and-forget executor.
A bulleted imperative like {match} tells the agent to never reveal, disclose, or mention something to the user. Used adversarially it can instruct the agent to hide its tool calls or lie about what it did — stripping the transparency a user relies on to trust the agent.

SynapBus is its own OAuth 2.1 identity provider. MCP clients (Claude Code, Gemini CLI, etc.) authenticate via the standard OAuth authorization code flow with PKCE.
How it works:
GET /.well-known/oauth-authorization-serverPOST /oauth/register (RFC 7591)tools/call requestsLocal setup (default) — no extra config needed:
./bin/synapbus serve --port 8080 --data ./data
# MCP clients connect to http://localhost:8080/mcpLAN or remote setup — set SYNAPBUS_BASE_URL so OAuth metadata returns correct endpoints:
# On a LAN server
SYNAPBUS_BASE_URL=http://192.168.1.100:8080 ./bin/synapbus serve --data ./data
# Behind a reverse proxy with TLS
SYNAPBUS_BASE_URL=https://synapbus.example.com ./bin/synapbus serve --data ./dataMCP client configuration (e.g., ~/.claude/mcp_config.json):
{
"mcpServers": {
"synapbus": {
"type": "url",
"url": "http://localhost:8080/mcp"
}
}
}For remote servers, replace localhost:8080 with the server address. OAuth login will open in your browser automatically.
