Connect to an OpenWrt router via SSH. Must be called before using any other tools.

Disconnect from the currently connected OpenWrt router (SSH).

Connect to an OpenWrt router via serial port (UART/COM). Useful for boot logs, recovery, and low-level debugging.

Disconnect from the serial port.

List available serial ports on the system.

Read the serial port output buffer. Captures all serial output including boot messages, kernel logs, and command output.

Write raw data directly to the serial port. Use for sending special key sequences, break signals, or interacting with bootloaders.

Switch the active transport between SSH and serial. Both connections can be maintained simultaneously — this controls which one is used for command execution.

Check the current connection status to the router. Shows SSH, serial, and active transport info.

Execute a shell command on the OpenWrt router. Use for any command-line operation not covered by specialized tools.

Show UCI configuration. Can show all configs, a specific config, or a specific section/option.

Get a specific UCI option value.

Set a UCI option value.

Add an anonymous UCI section of a given type to a config.

Delete a UCI section or option.

Add an item to a UCI list option.

Remove an item from a UCI list option.

Commit pending UCI changes to make them persistent. Optionally restart the affected service.

Show pending (uncommitted) UCI changes.

Revert pending UCI changes.

List all network interfaces and their status on the OpenWrt router.

Get the status of a specific UCI network interface using netifd.

Get wireless radio and interface status.

Scan for nearby wireless networks.

List currently connected network clients (DHCP leases and ARP table).

Restart the network service or a specific interface.

Show the current firewall rules and zones.

Ping a host from the router to test connectivity.

Perform DNS lookup from the router.

Show the routing table.

Get comprehensive system information from the OpenWrt router.

Read the system log (logread) with optional filtering.

Read the kernel log (dmesg).

List running processes on the router.

List available init.d services and their status.

Perform an action on an init.d service (start, stop, restart, enable, disable).

Reboot the OpenWrt router. WARNING: This will disconnect the SSH session.

List current crontab entries on the router.

Read the contents of a file on the OpenWrt router. For large files, use offset and limit to read in chunks. Returns file metadata (total lines and size) alongside content.

Write content to a file on the OpenWrt router. Creates the file if it doesn't exist.

List files and directories at a given path on the router.

Delete a file or directory on the router.

Search for files or content within files on the router.

Read multiple files at once for better performance. Returns all file contents in one call.

Apply a unified diff patch to a file on the OpenWrt router. The patch is parsed and applied on the MCP server side — no 'patch' command needed on the router. Supports standard unified diff format (output of 'diff -u').

Add one or more sed expressions to the batch queue for a file. Expressions are NOT executed immediately — they accumulate until sed_execute is called. This allows building up complex multi-edit operations efficiently.

Preview all pending sed expressions in the batch queue. Optionally preview the result on a specific file (dry run with sed, no modification).

Execute all pending sed expressions in the batch queue. Each file is edited in-place with a backup (.sed.bak). All expressions for a file are combined into a single sed command for atomicity.

Clear pending sed expressions from the batch queue.

View modification history for files on the router. Shows all changes made through MCP tools (write, patch, sed, chmod, delete) with timestamps and details.

Change file permissions on the router.

Update the opkg package lists from configured repositories.

List available or installed packages.

Install a package via opkg.

Remove an installed package via opkg.

Show detailed information about a package.

List packages that have upgrades available.
