Is Docfork MCP server safe?

The code builds an OS command out of values that can change at runtime, then runs it through a shell.

exec(`${cmd} "${url}"`, () => {

Why it matters: If any of those values come from untrusted input, an attacker can run their own commands on the machine.

Fix: Use execFile/spawn with an argument array instead of exec; never build a shell command string from external input.

package.json runs scripts automatically when the package is installed.

"preinstall": "npx only-allow pnpm",

Why it matters: Install scripts are a favorite supply-chain foothold — they execute on every machine that installs the package.

Fix: Inspect the hook command. Install-time scripts are a common supply chain execution vector; ensure they do nothing beyond a documented build step.

An MCP server entry launches a command on your host.

"command": "node",

Why it matters: Trusting the manifest means running that binary — verify what it is and where it comes from.

Fix: Verify the launched command and its source before trusting this MCP server configuration.

The component can run operating-system commands or spawn processes.

import { execFile } from "node:child_process";

import { exec } from "node:child_process";

exec(`${cmd} "${url}"`, () => {

Why it matters: Powerful and often legitimate — confirm the commands aren't built from untrusted input.

Fix: Confirm the command and its arguments are fully controlled and not derived from untrusted input; prefer execFile with an argument array.

The component makes outbound network requests.

response = await fetch(url.toString(), {

response = await fetch(url, {

response = await fetch(`${WORKOS_BASE_URL}/user_management/authorize/device`, {

response = await fetch(`${WORKOS_BASE_URL}/user_management/authenticate`, {

return fetch(TELEMETRY_URL, {

const response = await fetch(url.toString(), {

const response = await fetch(url.toString(), {

await fetch(TELEMETRY_URL, {

import { createServer, IncomingMessage, ServerResponse, Server } from "http";

const upstream = await fetch(`${AUTH_SERVER_URL}/.well-known/oauth-authorization-server`);

Why it matters: Usually legitimate, but confirm the destinations are expected and no sensitive data leaves.

Fix: Confirm the destination hosts are expected and that no sensitive data is sent off-host.

An MCP tool surface (manifest or tool definitions) was found.

"mcpServers": {

{

"mcpServers": {

{

{

const server = new McpServer(

server.registerTool(

server.registerTool(

const transport = new StreamableHTTPServerTransport({

const transport = new StdioServerTransport();

Why it matters: Just context — review which tools it offers and their permissions.

Fix: Review the declared MCP tools and their permissions.
