Claude Code

Hosted (recommended)

claude mcp add --transport http alt https://mcp.altlaboratories.com/mcp \
  --header "Authorization: Bearer alt_live_..."

Local stdio via the CLI

npm install -g @altlabs/cli
alt auth login          # paste your key once
claude mcp add alt-local -- alt mcp serve

alt mcp serve runs the same server locally using your stored key - useful when you want the key kept in ~/.config/alt/config.json instead of the MCP client’s config.
