Extensions and MCP servers

Add anything Jevie can't do yet: install from the store, bring your Raycast extensions over, have one written for you, or connect dozens of services through MCP.

From Raycast

• install the steam extension from raycastport the raycast spotify extensionA Raycast extension, run as it is: its lists, documents and forms as Jevie's own, on the Mac, Windows and Linux
• @hacker-news frontpage show hn@steam search games portalOne of its commands; the words after its name are what you would type in Raycast's search bar, or the dropdown entry they name
• import from raycastundo the raycast importSnippets, quicklinks, scripts, shortcuts and notes, from Raycast 1 or Raycast 2, all reversible. On Raycast 2, run its Export Settings & Data with no password first: Raycast 2 keeps its own data locked, so without an export Jevie reads Raycast 1's data as it was when Raycast 2 moved in
• script commandsadd script folder ~/raycast-scriptsYour own scripts, run by their title (see Script commands)

MCP servers

• mcp serversThe servers Jevie can call, connected or not
• connect lineardisconnect linearSign in to a service once, or forget it
• @github my open pull requests@context7 next.js caching docsA server named, its tool chosen for you
• @git git_log repo_path=~/code max_count=5A tool called exactly as written

How it works

An extension adds tools, commands or whole new things to ask about, and Jevie still decides what a sentence means and asks before anything that changes something. Extensions load only as you approved them; a changed one waits for your yes again.

Dozens of services connect through MCP, from open ones like web search and library docs to Linear, Notion, Figma, Slack and GitHub. Answers come back as Jevie's own tables, cards and lists. Tools that only read run at once; anything that writes is shown first and waits for your yes.

Limits

• Raycast extensions come over one at a time, never a whole setup in bulk; AI chats, history and extension settings stay behind.
• A Raycast command is run once for each sentence, so each search is a sentence of its own. Its menu-bar commands do not run, and it cannot use Raycast AI, your selected text or the Trash. When it asks are you sure?, nothing happens until you say yes.
• Calling a tool in words sends your sentence and the tool's description to Jevie's fast model; written-out calls send nothing.
• GitHub through gh is read-only; a GitHub server you add can never push or delete.
• Servers that drive a screen, a browser or another app are used only when you name them.

Where it's kept

~/.jevie/extensions (installed and made extensions), ~/.jevie/mcp.json (your servers), ~/.jevie/mcp-auth/ (sign-ins, readable only by you).

In Jevie, help extension answers from this page as you type.
