mcp_call_conda_info
Retrieve Conda installation details and environment information to diagnose Python configuration issues and understand system setup.
Instructions
Get comprehensive information about the Conda installation on this system.
If env_name is provided, it will return the information for the specified
environment as well.
Returns detailed information including:
- Conda version and configuration
- Python version and virtual packages
- Base environment location
- Channel URLs and package cache locations
- Platform and system details
- Complete list of all Conda environments with their paths
- Complete list of all packages in the specified environment and their versions
This is useful for diagnosing Conda-related issues or understanding
the Python environment configuration on this system.Input Schema
