description: Call a Tauri IPC command with arguments and view the response
allowed-tools: mcp__tauri-mcp__call_ipc_command, mcp__tauri-mcp__list_ipc_handlers
author: Quintin Henry (https://github.com/qdhenry/)

<objective> Invoke a Tauri IPC command (same as frontend `invoke()` calls) directly from the command line. Useful for testing backend commands without UI interaction. </objective>

<instructions> Call IPC command: **$ARGUMENTS**

Arguments format: `[process_id] [command_name] [args_json]`

• `process_id`: Required - the process ID from `/tauri:launch`
• `command_name`: Required - the IPC command name (e.g., `get_projects`)
• `args_json`: Optional - JSON object with command arguments

Process

1. **Parse Arguments** Extract process_id, command_name, and optional args from $ARGUMENTS.

2. **Call the IPC Command** Use `mcp__tauri-mcp__call_ipc_command` with:

• `process_id`: Target process
• `command_name`: The Tauri command to invoke
• `args`: JSON object with parameters (if any)

3. **Format Response**

• Pretty-print JSON responses
• Highlight errors or unexpected results
• Show timing information if available

Usage Examples

# Simple command with no args
/tauri:call-ipc 12345 get_projects

# Command with arguments
/tauri:call-ipc 12345 get_project {"id": "abc-123"}

# Create operation
/tauri:call-ipc 12345 create_task {"title": "Test Task", "project_id": "proj-1"}

# Update with complex args
/tauri:call-ipc 12345 update_task_status {"task_id": "task-1", "status": "completed"}

</instructions>

<output_format>

=== IPC Call Result ===
Command: [command_name]
Process: [PID]

--- Request ---
Args: [formatted JSON args]

--- Response ---
[formatted JSON response]

--- Timing ---
Duration: [X]ms

For errors:

<common_patterns> **CRUD Operations:**

# Create
/tauri:call-ipc [pid] create_[entity] {"field": "value"}

# Read
/tauri:call-ipc [pid] get_[entity] {"id": "..."}
/tauri:call-ipc [pid] list_[entities] {}

# Update
/tauri:call-ipc [pid] update_[entity] {"id": "...", "field": "new_value"}

# Delete
/tauri:call-ipc [pid] delete_[entity] {"id": "..."}

**Query with Filters:**

/tauri:call-ipc [pid] search_tasks {"query": "bug", "status": "open"}

</common_patterns>

<troubleshooting> **"Command not found":**

• Run `/tauri:list-commands [pid]` to see available commands
• Check command name spelling (snake_case)

**"Invalid arguments":**

• Verify JSON syntax is valid
• Check required fields for the command
• Look at Rust command definition for expected types

**"Serialization error":**

• Ensure argument types match (string vs number vs boolean)
• Check for missing required fields
