# MCP-Tasks CLI Reference

This skill provides comprehensive CLI reference for the mcp-tasks command-line tool.

## Overview

The mcp-tasks CLI provides task management via command-line interface for scripting and automation. For agent workflows, use the MCP server instead.

## Installation

The CLI is distributed as a pre-built Babashka uberscript in this plugin:
```bash
plugins/mcp-tasks-cli/bin/mcp-tasks
```

Add to PATH or invoke directly:
```bash
# Add to PATH (example)
export PATH="$PATH:/path/to/plugins/mcp-tasks-cli/bin"

# Or invoke directly
/path/to/plugins/mcp-tasks-cli/bin/mcp-tasks --help
```

## Configuration Discovery

No `--config-path` required. The CLI automatically searches for `.mcp-tasks.edn`:
- Starts from current directory
- Traverses up directory tree
- Stops at filesystem root or when found

Example:
```bash
# Project structure:
# /project/.mcp-tasks.edn
# /project/src/

# Works from any subdirectory:
cd /project/src
mcp-tasks list  # Finds /project/.mcp-tasks.edn
```

mcp-tasks delete --title-pattern "old-task"

# Delete with human-readable output
mcp-tasks delete --id 42 --format human
```

## Output Formats

### EDN (Default)

Clojure EDN format suitable for programmatic consumption:
```clojure
{:tasks [{:id 42 :title "Fix bug" :status :open ...}]
 :metadata {:open-task-count 5 :returned-count 1}}
```

### JSON

JSON format for integration with non-Clojure tools:
```json
{
  "tasks": [{"id": 42, "title": "Fix bug", "status": "open", ...}],
  "metadata": {"open_task_count": 5, "returned_count": 1}
}
```

### Human

Human-readable tabular format:
```
Tasks (1 found, showing 1):

ID  | Status | Category | Type | Title
----|--------|----------|------|--------
42  | open   | simple   | task | Fix bug

Metadata:
  Open tasks: 5
  Returned: 1
```

## Common Workflows

### Query and Display
```bash
# Find tasks by status and category
mcp-tasks list --status open --category medium --format human

# Show specific task details
mcp-tasks show --task-id 42 --format human
```

### Create and Manage Tasks
```bash
# Create simple task
mcp-tasks add --category simple --title "Fix parser"

# Create story with child tasks
mcp-tasks add --category large --title "User auth" --type story
mcp-tasks add --category medium --title "Login" --parent-id 100

# Update task status
mcp-tasks update --task-id 101 --status in-progress

# Complete task with comment
mcp-tasks complete --task-id 101 --comment "Implemented"
```

### Scripting Examples
```bash
# Get open task count (JSON + jq)
mcp-tasks list --status open --format json | jq '.metadata.open_task_count'

# List all story tasks
mcp-tasks list --type story --status any --format human

# Batch update tasks (shell loop)
for id in 42 43 44; do
  mcp-tasks update --task-id $id --status closed
done
```

## File Locations

The CLI operates on these files within the `.mcp-tasks/` directory:

| File | Purpose |
|------|---------|
| `.mcp-tasks.edn` | Configuration file (searched automatically) |
| `.mcp-tasks/tasks.ednl` | Incomplete tasks |
| `.mcp-tasks/complete.ednl` | Completed/deleted tasks archive |
| `.mcp-tasks/prompts/<category>.md` | Category-specific prompts (not used by CLI) |

## CLI vs MCP Server

**Use CLI for:**
- Shell scripting and automation
- CI/CD pipelines
- Batch operations
- Quick queries from terminal
- Integration with non-agent tools

**Use MCP Server for:**
- Agent-driven task execution
- Interactive task refinement
- Workflow automation with prompts
- Story-based development
- Git integration (branches, worktrees)

The CLI and MCP server operate on the same `.mcp-tasks/` data files and can be used interchangeably.

## Error Handling

**Configuration not found:**
```
Error: Could not find .mcp-tasks.edn in current directory or any parent directory
```
Solution: Initialize project with `.mcp-tasks.edn` or run from correct directory.

**Unknown option:**
```
Unknown option: --invalid. Use --help to see valid options.
```
Solution: Check command-specific help with `mcp-tasks <command> --help`.

**Invalid format:**
```
Invalid format: xml. Must be one of: edn, json, human
```
Solution: Use one of the supported format values.

**Missing required argument:**
```
Required option: --task-id (or --id)
```
Solution: Provide all required arguments for the command.

**Task not found:**
```
Error: No task found with task-id: 999
```
Solution: Verify task ID exists using `mcp-tasks list`.

## Limitations

- No interactive prompts (use flags for all input)
- No task execution workflows (use MCP server)
- No git integration (use MCP server)
- No worktree management (use MCP server)
- No branch automation (use MCP server)
