Laika Orbit MCP Server

Laika Orbit

A cockpit for your coding agents. Run many Claude Code chats at once. Orbit keeps them moving, puts what needs you first, and sits beside the editor you already use. Open source, and it all runs on your own Mac.

Status: macOS preview. Built and used daily on macOS, and built with itself (how). The recall engine, CLI and MCP server run anywhere Node runs; the desktop app is macOS first, Linux best effort, Windows untested.

What it does

Give it a goal. It runs the fleet. A conductor chat sends each of your chats its next step. Switch to Away and it keeps them going: plainly safe steps are approved, stuck chats are brought back, and anything that reaches outside your Mac waits for you. Come back to one summary card. Away mode.

Every chat, and what each one needs. Chats run side by side, one per task, on any of your Claude accounts, and come back after a restart or a crash. The fleet board puts the ones waiting on you at the top.

Long jobs report themselves. Builds, test runs and batch jobs share one runs page, with progress, an ETA, and before/after compares. A job that goes quiet is flagged as stalled.

Work that waits its turn. A queue of next tasks that survives restarts. With autopilot on, the next item starts by itself when a chat frees up.

Heavy work goes to your other machines. Tests, builds and captures run on a Linux box under the desk and the files come back (below). Windows PCs for GPU work are in testing.

And the rest of your day in the same window: panels you dock and lay out, a real Chromium browser with a profile per account, inbox and calendar widgets, and a live map of everything you know. Hidden panels stop drawing: idle, the app went from 41% of one CPU core to 11%, and to 5.5% while you're in another window.

Finished work folds itself into main (new). Each chat shows its branch, its commits and its uncommitted files. Mark a chat's work ready and the merge train lands it on your local main once the repo's own check passes. If the check goes red, it finds which chat's work broke it, lands the rest, and sends that chat the failing output. Pushing stays with you.

Laika Orbit recall

Underneath is Laika Orbit recall, a retrieval engine that answers questions about your files without calling a model: the exact section and the file it came from, in about a millisecond, with 97.8% fewer tokens than an agent grepping and reading whole files (bench/RESULTS.md). It works in any Claude Code session on its own:

claude mcp add laikaorbit -- npx -y laikaorbit mcp

Requirements

• Node 22.18 or newer (runs TypeScript directly) and pnpm 10. mise install sets up both.
• macOS for the desktop app. pdftotext for PDF indexing: brew install poppler.
• Your own Claude account for chats. Sign in from the Claude panel; it runs Claude Code's own login, and Laika Orbit never sees or stores your credentials. Until then, a demo agent runs offline so you can try the panel.

Quick start

git clone https://github.com/Laika-Dynamics-Ltd/laika-orbit.git && cd laika-orbit
mise install && pnpm install

cd packages/app && node server.mjs    # the app at http://localhost:5200
pnpm shell                            # (from the root) the same app in its own window, with real browser tabs

The first run indexes this folder only. Add your own folders (notes, projects, documents) from the index settings (i); nothing outside the repo is read until you add it.

The engine on its own

node packages/cli/src/index.ts index                          # build the index
node packages/cli/src/index.ts recall "which TTS voice do we use"
node packages/cli/src/index.ts lint                           # router-file diagnostics

Claude Code picks up the MCP server from .mcp.json when you open this folder. BRAIN_ROOT points any of it at another corpus:

cd packages/app && BRAIN_ROOT="$HOME/Documents" PORT=5201 node server.mjs

Configuration

Everything is optional. Copy .env.example to .env.local for the feeds:

Files ending .local.json, .env.local, and the settings the app writes as you use it are gitignored, so pulling updates never conflicts with your setup.

Privacy and security

• Local only. The server listens on 127.0.0.1 and refuses requests with any other Host, and cross-site requests that would change something are refused. There is no login, so don't expose the port.
• What leaves your machine: chats go to Anthropic through Claude Code under your account; the inbox and calendar widgets fetch from Google with the credentials you configure. After each chat turn a short summary is written by a small model on the same account; LAIKA_BRIEFS=0 turns that off.
• Chats ask before acting. New chats start in Claude Code's default permission mode; you choose when to allow more.
• Usage reporting is opt-in and anonymous. Off until you turn it on, and declining never creates an identifier. It sends daily counts of coarse actions (recall_run: 40) and never a path, query, file, prompt, URL or IP. Turning it off destroys the id and the queue. PRIVACY.md lists the whole payload.

Other machines

Claude sessions and terminals can run on other machines on your network, so their builds and tests don't load your Mac. pnpm node:bundle builds one archive per platform (Linux x64 and arm64 by default; darwin-arm64 and darwin-x64 on request) in tools/node-bundle/dist/. Copy one to the machine, then tar -xzf it and run ./install.sh as the user the sessions should run as. It bundles Node and Claude Code, installs the agent host as a user service listening on loopback only, and lets this Mac's Laika Orbit key (~/.laika/node/) open an SSH tunnel to it and nothing else. See tools/node-bundle/README.txt.

packages/app/offload.mjs sends a command to the least busy machine as if it ran here: it copies the project over (rsync, without Unity's Library), runs the command there, streams the output back, brings its result files home and exits with its code. For Unity, offload unity -- -nographics -runTests -testResults out/tests.xml runs the project's own Unity version and brings the results back. offload add user@host adds a machine, offload machines shows them, offload discover lists the ones announcing themselves on the network.

How recall works

Seven steps, each a pure function with its own tests, none of them a model call:

1. tokenise: lowercase, strip punctuation, drop a stop list, matched on word boundaries so everyone and milestone survive.
2. score: sum weights across the inverted index. No file is opened yet.
3. select: top 5 with a confidence margin; two sources come back when the result is ambiguous, and say so.
4. read: open only the winner.
5. sliceOf: keep the ## section whose heading matches, or a window around the densest line.
6. hop: follow at most one pointer out of that slice. Hard cap, enforced by test.
7. buildAsk: question, evidence, one instruction. 9KB cap.

Recall quality is bounded by your router files, not the engine. brain/routers/ holds typed pointer files that act as a curated index:

- Skills:    script-writing — full script generation
- Files:     shared/projects/C-*/script.md — in-progress scripts
- Rules:     brain/rules/feedback_au_english.md — AU spelling always

Write descriptions the way a question is phrased. Pointed at a folder with no routers, recall is a very fast filename and content search; with them, it answers.
