influship-api-mcp@0.21.0

The official MCP Server for the Influship API

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The package is not proven malware, but its default MCP execution feature exposes inherited environment data to caller-controlled code. This warrants a warning as a dangerous capability rather than a publication block.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

An MCP caller invokes the execute tool with code.

Impact

A malicious MCP request or agent prompt could access inherited environment variables and use the permitted API connection.

Mechanism

Dynamic execution of caller-supplied TypeScript in a privileged worker.

AI rationale

Evidence

src/server.tssrc/code-tool.tssrc/code-tool-worker.ts

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The default MCP tool exposes caller-supplied TypeScript execution.
The worker dynamically imports and invokes supplied code.
The worker receives the parent environment and permits environment access.

Evidence against

package.json has no preinstall, install, or postinstall lifecycle hook.
No package code directly harvests or sends credentials to a hard-coded external receiver.
The worker limits network permission to the configured API host.
