influship-api-mcp@0.20.1

The official MCP Server for the Influship API

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The package exposes an MCP API client with explicit remote or local code-execution modes, but has no install hook or hidden persistence behavior. The flagged primitives are package-aligned and tool-invoked rather than a concrete malicious chain.

Static reason

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

Trigger

An MCP client invokes the execute tool.

Impact

The configured API key and submitted code are provided to the selected code-execution service.

Mechanism

User-requested API code execution through a configured sandbox.

Decision evidence

public snapshot

AI called this Clean at 84.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

The execute tool sends submitted code and the Influship API key to a Stainless-hosted endpoint when invoked.
The optional local mode evaluates caller-supplied code in a Deno worker.
Startup fetches MCP instructions from a Stainless endpoint.
The reviewed local documentation module contains embedded method data, not collection logic.
The declared scripts are test, build, format, tsn, lint, and fix.
The remote code-tool handler sends a POST request to its configured endpoint.
The TypeScript source sends remote code-tool requests with POST.
The worker evaluates the supplied code and invokes its exported run function with an SDK proxy.

Evidence against

package.json has no preinstall, install, or postinstall hook.
The executable entry point runs only when invoked as the command-line program.
Remote calls and code evaluation are explicit MCP tool behavior, not import-time activity.
No source showed persistence, broad file harvesting, destructive actions, or unrelated exfiltration.
