Nash MCP Server
local-only server
The server can only run on the client’s local machine because it depends on local resources.
Integrations
Nash MCP uses .env files to specify data file paths for configuration
Nash MCP provides command execution capabilities that can run git commands with proper error handling and output capture
Nash MCP enables execution of Python code snippets with full access to installed packages and provides information about available Python packages
Nash MCP Server
Nash MCP (a Model Context Protocol (MCP) server) enables seamless execution of commands, Python code, web content fetching, and reusable task management.
Requirements
- Python 3.11+
- Poetry package manager (recommended)
Installation
Features
- Command Execution: Run shell commands with error handling
- Python Execution: Execute Python code with error handling
- Secure Credentials: Store and access API keys without exposing sensitive data to the LLM
- Web Content Access: Fetch and parse webpage content for analysis
- Task Repository: Save and organize reusable workflows and scripts
Tools
Execute Module
- execute_command: Run shell commands with proper error handling and output capture
- execute_python: Execute Python code snippets with full access to installed packages
- list_installed_packages: Get information about available Python packages
Web Interaction
- fetch_webpage: Retrieve and convert webpage content to readable text format
Secrets Management
- nash_secrets: Access stored API keys and credentials securely. Accessible via environment variables in scripts.
Task Management
- save_nash_task: Create reusable tasks with embedded scripts
- list_nash_tasks: View all available saved tasks
- run_nash_task: Retrieve and display a previously saved task
- execute_task_script: Run a specific script from a saved task
- view_task_details: See complete details of a task, including script code
- delete_nash_task: Remove tasks that are no longer needed
Running
This is the command to use for MCP config files
As an example, if you were to use this MCP with Claude Desktop, you would change your ~/Library/Application Support/Claude/claude_desktop_config.json to:
Environment Variables
Nash MCP requires environment variables to specify all data file paths. Create a .env file in the root directory with the following variables:
There are no default values - all paths must be explicitly configured.
Security Considerations
- Commands and scripts run with the same permissions as the MCP server
- API keys and credentials are stored locally and loaded as environment variables
- Always review scripts before execution, especially when working with sensitive data
Development
Logs
Detailed timestamped logs of all operations and tool executions are emitted by the server. These logs are stored in the directory specified by the NASH_LOGS_PATH environment variable.
