Local System Tools
Tools for local filesystem operations, shell commands, and calculations.
File System Operations
Write file
result = await filesystem_write_file(
content="Hello, World!",
filename="example.txt",
directory="/path/to/dir"
)
Read file
result = await filesystem_read_file(filename="example.txt", directory="/path/to/dir")
# Returns: {"success": True, "data": {"content": "Hello, World!", ...}}
List files
result = await filesystem_list_files(
directory="/path/to/dir",
pattern="*.txt",
recursive=True
)
File operations
# Check existence
result = await filesystem_file_exists(filename="test.txt")
# Get info
result = await filesystem_get_file_info(filename="test.txt")
# Delete
result = await filesystem_delete_file(filename="test.txt")
# Append
result = await filesystem_append_to_file(content="More text", filename="test.txt")
# Copy
result = await filesystem_copy_file(
source_filename="original.txt",
destination_filename="copy.txt"
)
Create directory
result = await filesystem_create_directory(directory="/new/path", parents=True)
Security
By default, file operations are restricted to the current working directory.
Set HUMCP_ALLOW_ABSOLUTE_PATHS=true to allow operations outside cwd.
Shell Commands
Run script
result = await shell_run_shell_script(
script="echo 'Hello'\nls -la",
shell="/bin/bash",
timeout=30
)
Check command exists
result = await shell_check_command_exists(command="git")
# Returns: {"success": True, "data": {"exists": True, "path": "/usr/bin/git"}}
Get environment variable
result = await shell_get_environment_variable(variable_name="HOME")
Get system info
result = await shell_get_system_info()
# Returns OS, platform, Python version, hostname, etc.
Get current directory
result = await shell_get_current_directory()
Calculator
Basic operations
result = await calculator_add(a=5, b=3) # 8
result = await calculator_subtract(a=10, b=4) # 6
result = await calculator_multiply(a=6, b=7) # 42
result = await calculator_divide(a=20, b=4) # 5.0
Advanced operations
result = await calculator_power(base=2, exponent=10) # 1024
result = await calculator_sqrt(number=144) # 12.0
result = await calculator_percentage(value=50, total=200) # 25.0
Response Format
All tools return:
{
"success": true,
"data": { ... }
}
On error:
{
"success": false,
"error": "Error description"
}
