Is Browserbase MCP server safe?

An MCP server entry launches a command on your host.

"command": "npx",

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 reads files from disk.

const configContent = await fs.readFile(configPath, "utf-8");

const packageJSONBuffer = fs.readFileSync(packageJSONPath);

Why it matters: Usually legitimate, but worth confirming it can't be steered into reading sensitive files.

Fix: Confirm which files are read and that paths cannot be influenced by untrusted input to reach sensitive locations.

The component writes or deletes files on disk.

await fs.writeFile(wfPath, JSON.stringify(wfConfig, null, 2));

await Promise.all(workflowFiles.map((f) => fs.unlink(f)));

await fs.rmdir(tmpDir);

await fs.writeFile(

Why it matters: Usually legitimate, but worth confirming the paths can't be controlled by untrusted input.

Fix: Confirm which files are written/deleted and that paths cannot be influenced by untrusted input.

package.json has a 'prepare' script (runs on git/local installs and before publishing).

"prepare": "husky && pnpm build",

Why it matters: Usually a build step, but confirm it doesn't fetch or run remote code.

Fix: Usually a legitimate build step; confirm it only builds and does not fetch or execute remote code.

The component makes outbound network requests.

import http from "node:http";

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": {

{

const server = new McpServer({

await server.connect(new StdioServerTransport());

const transport = new StreamableHTTPServerTransport({

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

Fix: Review the declared MCP tools and their permissions.
