terminal-progress-bar

One progress, two interfaces: terminal for you, MCP for the AI.

Shared terminal progress bars for parallel scripts and processes. Track multiple jobs from different terminals or scripts and watch them update in real time.

Install

uv tool install -e .

Or from a clone of this repository:

git clone https://github.com/you/terminal-progress-bar.git
cd terminal-progress-bar
uv tool install -e .

Editable install (-e) keeps tpb linked to the source tree, so local changes take effect without reinstalling.

Related MCP server: Terminally MCP

Usage

Run tpb --help for an overview, or tpb <command> --help for command details (e.g. tpb create --help).

Create a progress bar

tpb create backup-db 0 100 "Database backup"

Update progress

tpb backup-db 35        # set absolute value
tpb backup-db +5        # increment
tpb backup-db -2        # decrement
tpb message backup-db "Importing users table"

Finish or fail

tpb done backup-db "completed in 2m"
tpb error backup-db "connection timeout"

List, status, remove

tpb                     # visual progress bars (Rich)
tpb list                # plain text: slug, current, max, status, label
tpb status backup-db    # machine-readable plain text output for one bar
tpb rm backup-db        # remove a bar

Monitor in real time

tpb monitor

The monitor redraws the screen when any progress bar changes. Bars stay visible until removed with tpb rm. Press q to exit.

Storage

Each progress bar is stored as a separate JSON file:

~/.config/terminal-progress-bar/<slug>.json

Example:

{
  "slug": "backup-db",
  "label": "Database backup",
  "current": 35,
  "max": 100,
  "status": "active",
  "status_text": "",
  "created_at": "2026-07-30T12:00:00Z",
  "updated_at": "2026-07-30T12:05:00Z"
}

Bars are listed in creation order (created_at).

List output

tpb list prints one tab-separated line per bar:

import-data	25	100	active	Import data
backup-db	100	100	done	Database backup

Columns: slug, current, max, status, label, and status_text (only when set).

Status output

tpb status <slug> prints plain key: value lines for scripting and AI agents:

slug: backup-db
label: Database backup
current: 35
max: 100
status: active
status_text:
created_at: 2026-07-30T12:00:00Z
updated_at: 2026-07-30T12:05:00Z

MCP Server

The package includes an MCP server (tpb-mcp) for AI clients to manage progress bars programmatically over stdio.

Run

After install:

tpb-mcp

From a clone without global install:

uv run tpb-mcp

Client configuration

Example MCP client config:

{
  "mcpServers": {
    "terminal-progress-bar": {
      "command": "tpb-mcp",
      "args": []
    }
  }
}

From the repository:

{
  "mcpServers": {
    "terminal-progress-bar": {
      "command": "uv",
      "args": ["run", "tpb-mcp"],
      "cwd": "/path/to/terminal-progress-bar"
    }
  }
}

Tools

Example flow: tpb_create → tpb_update / tpb_increment → tpb_message → tpb_done.

Tools return structured JSON (bar fields as dict). The human tpb monitor view updates automatically when bars change on disk.

Development

uv sync --group dev
uv run pytest
