Exposed MCP Tools (3)

high

wcgw

Provides general system operations and file management capabilities.

Allows file system writes and potentially execution of system commands.

moderate

fetch

Enables making HTTP requests to external resources.

Can be used to access external resources, potentially leading to data exfiltration or SSRF attacks.

Allows searching the web using the Brave search API.

Primarily a read-only operation, limited to searching and retrieving information.

Safety Assessment

ws-mcp's safety depends heavily on the configuration and the security of the underlying MCP servers it exposes. It is relatively safe when used with read-only servers and properly configured access controls. However, it becomes risky when exposing servers with write or execute capabilities without adequate security measures.

Relies on underlying MCP servers for security.
Configuration file allows control over exposed servers.
WebSocket provides a standardized communication channel.
Can be deployed in sandboxed environments.

Exposes MCP servers to network access.
Security depends on the configuration of individual MCP servers.
Improper configuration can lead to unauthorized access.
Potential for command injection if input sanitization is lacking in underlying servers.
Secrets management depends on the underlying servers.
