Social layer for Claude Code - DMs, presence, Matrix multiplayer rooms, and connection between AI-assisted developers

AI Security Review

scanned 2d ago · by lpm-firewall-ai

No confirmed malicious attack surface was found. Network calls, config writes, local auth storage, git inspection, and optional hook helpers are aligned with the advertised /vibe MCP collaboration product and require runtime/user-invoked actions.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User runs the MCP server or setup command, then invokes vibe tools/authentication.

Impact

Stores auth/config under ~/.vibe, sends social/presence/messaging data to slashvibe.dev, and can add a Claude MCP server entry during setup.

Mechanism

User-invoked MCP social client with OAuth, presence, messaging, and optional local configuration writes.

Rationale

Static source inspection found broad network and local configuration behavior, but it is tied to the package's declared MCP social/collaboration functionality and user-invoked setup/auth flows. No lifecycle execution, hidden exfiltration, destructive persistence, or unconsented AI-agent control-surface mutation was identified.

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with medium false-positive risk.

Evidence for block

Evidence against

package.json has no preinstall/postinstall lifecycle scripts; bin entries are cli.js and setup.js only.
setup.js modifies Claude MCP config only when user runs setup/TTY CLI, adding npx slashvibe-mcp@latest for the advertised MCP server.
index.js starts an MCP server and exposes vibe_* social/presence/messaging tools; no import-time credential harvesting found.
tools/subscriptions.js sends the stored auth token only as Authorization to configured VIBE_API_URL/default slashvibe.dev for the subscription feature.
tools/_work-context.js gathers bounded git/project context, uses execFileSync with shell:false, redacts common secrets, and is used for presence context.
hooks/check-guest-messages.* are shipped helper hooks but are not installed by package lifecycle; injected external messages include safety warnings.
