Exposed MCP Tools (5)

critical

execute_shell_command

Unrestricted shell access can lead to arbitrary code execution.

moderate

read_file

Reads the content of a file from the filesystem.

Can expose sensitive information if not properly controlled.

high

write_file

Writes content to a file on the filesystem.

Can modify system files or user data.

safe

search_web

Searches the web for information.

Read-only operation with no direct side effects.

safe

get_current_time

Retrieves the current date and time.

Read-only operation with no side effects.

Safety Assessment

The MCP CLI offers a balance of functionality and security. It is relatively safe when used with local LLMs and filesystem access disabled. However, using cloud providers and enabling tool execution introduces risks that require careful configuration and monitoring.

Supports local LLMs (Ollama) for privacy-focused operation.
Offers configurable access to cloud-based LLM providers.
Includes middleware for tool execution (retry, circuit breaker, rate limiting).
Provides options to disable filesystem access.

Can execute tools with potentially destructive capabilities.
Relies on user-provided API keys for cloud providers.
Configuration errors could expose sensitive information.
Tool execution is not fully sandboxed by default.
