tai is the single command-line entrypoint for operating a server from the terminal. It groups every surface — tools, presets, agents, connectors, keys, schedules, and more — under one command tree. The per-group pages in this section render from the live command tree, so their usage and options never drift from the code.
Run tai --help, or tai <command> --help, for the same tree these pages document.

​
Command groups

serve

Boot a server locally.

tools

Inspect and manage registered tools.

agents

Inspect and manage agents.

presets

Manage versioned tool presets.

connectors

Manage OAuth connectors.

plugins

Browse the marketplace and install plugins.

keys

Mint and manage API keys.

config

Inspect the resolved configuration.

doctor

Diagnose the local environment.

​
Global options

These flags apply to every command:
There is no --api-key VALUE flag: a key on the command line leaks through ps and shell history. Supply the key through the environment, the config file, --api-key-stdin, or the interactive prompt.

​
Server URL resolution

tai resolves the server it talks to in this order, first match wins:
1

The --server flag

An explicit --server URL on the command line.
2

The TAI_SERVER_URL environment variable

Set it to point a shell session at a server.
3

The config file

The server_url key in config.toml.
4

The local default

http://127.0.0.1:8000 — the port comes from the same serve defaults tai serve uses, so the two always agree.

​
API-key resolution

The API key resolves in this order, first match wins:
1

--api-key-stdin

Read one line from stdin — the way to pass a key from a secret store.
2

The TAI_API_KEY environment variable

Set it for a shell session.
3

The config file

The api_key key in config.toml.
4

An interactive prompt

A hidden prompt, as a last resort.

​
Config file

tai reads a TOML config file at $XDG_CONFIG_HOME/tai/config.toml, or ~/.config/tai/config.toml when XDG_CONFIG_HOME is unset. It recognizes two keys:
A malformed config file raises loudly rather than being ignored.

​
Local vs remote commands

Most commands call the server’s HTTP API and so resolve a server URL and an API key. A few run locally and never contact a server — tai serve boots one, tai openapi emits the API spec offline, tai version and tai doctor inspect the local environment, and tai completion installs shell completion.
