Local-first memory & context harness for coding agents

AI Security Review

scanned 27d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package can alter existing workspace MCP configurations and register a local MCP server. The installer also supports user-level configuration injection for detected AI coding tools.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm postinstall during package installation when a supported workspace configuration exists.

Impact

A project or agent can be configured to launch GraphFlow through npx without an explicit setup command from the user.

Mechanism

Automatic MCP configuration injection for coding-agent control surfaces.

Policy narrative

The postinstall hook runs automatically. For a local install, it checks for existing Cursor, VS Code, or OpenCode MCP configuration in the consumer workspace, adds a GraphFlow server entry that launches through npx, and writes the modified configuration. Its companion installer detects multiple agent products and can inject user-level MCP entries. This changes foreign AI-agent execution configuration as an installation side effect rather than requiring the advertised explicit setup command.

AI rationale

The package performs unconsented postinstall mutation of existing workspace and agent MCP control surfaces. That is a concrete install-hook abuse path even though the reviewed code did not show install-time secret theft.
