Mistral Vibe

Prerequisites

Mistral Vibe installed
A LightOn API key from the LightOn Console

Configuration

Mistral Vibe configures MCP servers via a TOML file. Add the following to ~/.vibe/config.toml:

[[mcp_servers]]
name = "lighton"
transport = "http"
url = "https://api.lighton.ai/mcp"
api_key_env = "LIGHTON_API_KEY"
api_key_header = "Authorization"
api_key_format = "Bearer {token}"

api_key_env takes the name of an environment variable. Mistral Vibe reads the value at runtime on every request. Make sure LIGHTON_API_KEY is set in your shell environment, you can grab your key from the LightOn Console. To scope the server to a single project instead, place the same snippet in .vibe/config.toml at the root of your project.

Verification

Start a Mistral Vibe session.
Check that the lighton server is listed among the active MCP servers in the session output.

Test the connection with a prompt like:

Search my LightOn workspaces for documents about [topic]

You’re all set. From any Mistral Vibe session you can now ask it to search or ingest documents in your LightOn workspaces directly.
