lmstudio-agent-config

lmstudio-agent-config discovers models from LM Studio and generates local agent configuration for common developer clients.

Supported targets:

• VS Code + GitHub Copilot
• OpenCode
• Pi
• Codex

About

This tool reads LM Studio’s /api/v1/models endpoint, detects model capabilities, and produces client-specific configuration. You can print a model list or write config files directly for the supported targets, with optional filters for context length and capabilities.

Features

• Auto-discover LM Studio models from /api/v1/models.
• Detect tool calling, vision support, and context length.
• Generate configs for VS Code Copilot, OpenCode, Pi, and Codex.
• Preview changes with a focused diff and a confirmation prompt.
• Create dated backups before writing files.
• Filter by minimum context length, tools, and vision support.

How it works

• Queries LM Studio’s local server for available models.
• Builds target-specific configuration payloads.
• Either prints results or updates config files in place.

Safety behavior

When writing files, the tool is intentionally conservative. It prints a focused diff of only the changed lines, asks for confirmation (y/N), and only then writes the file. Before any modification, it creates a dated backup next to the original file (for example: settings.260215-0.backup.json), so you can roll back easily if needed.

Install

Run without install (PyPI):

uvx lmstudio-agent-config --help

Install with pip:

pip install lmstudio-agent-config

From source:

uv tool install .

Requirements

• LM Studio is running.
• The local server is enabled in LM Studio.
• The model listing endpoint is reachable (default: http://localhost:1234/api/v1/models).
• If LM Studio runs on another machine, use --base-url to point at that host and port.

Quick start

List discovered models:

lmstudio-agent-config

Write config for one target:

lmstudio-agent-config --settings code

Use a remote LM Studio server:

lmstudio-agent-config --base-url http://LMSTUDIO_HOST:1234/v1

Update all installed targets at once (skips missing default files):

lmstudio-agent-config --settings all

Usage

Use filters to control which models are included:

lmstudio-agent-config --min-context 32768
lmstudio-agent-config --tools
lmstudio-agent-config --no-tools
lmstudio-agent-config --vision
lmstudio-agent-config --no-vision
lmstudio-agent-config --min-context 32768 --tools --vision

Targets and default paths

Use --settings-path to override any default path.

Codex profiles

For Codex, the tool also generates one profile per discovered LM Studio model under profiles.*. Switch models with:

codex --profile lmstudio-your-model

Codex does not show these generated LM Studio profiles in a model picker, so use --profile explicitly when you want a non-default LM Studio model. The tool does not change top-level model_provider, so your default provider stays as-is.

Custom base URL

Use a custom LM Studio URL:

lmstudio-agent-config --base-url http://localhost:1234/v1

If LM Studio runs on another machine, you must point --base-url at that host and port.
