# Rune ᚱ
A high-performance, zero-trust AI agent built in Rust. Single binary, triple mode: interactive CLI assistant, Concourse CI resource type, and AI-native Data Exchange Hub (**Rune Notes**).
## Features
- **Zero-Trust Sandbox** — ALL tool executions run through 5 isolation layers (best-effort; the runtime applies these protections when available):
- cgroups v2 resource limits (`systemd-run --scope`) — memory/PID limits
- Network isolation (namespace or net-guard) (`unshare --user --net` or internal net-guard) — namespace-based isolation or domain-allowlist filtering
- Seccomp BPF syscall filter (internal) — syscall filtering
- Landlock filesystem restriction (internal) — file access limits
- DNS / Domain allowlist — selective outbound network access (configured via `allowed_domains`)
- **Tool Calling** — 9 built-in tools (5 standard sandboxed tools + 4 serve-mode notes tools): `read_file`, `write_file`, `list_dir`, `execute_cmd`, `fetch_url`, `list_markdown`, `read_markdown`, `write_markdown`, `search_chat`
- **Rune Notes (Data Exchange Hub)** — AI-native Markdown hub served from the same single binary. Exposes Web UI, MCP endpoint, and REST API. Connects external agents (OpenClaw, Hermes, Copilot, OpenCode, Antigravity) with first-party browser extensions (Rune Chat) and built-in AI chat over plain Markdown files
- **Rich Markdown System** — Math notation (KaTeX inline/block), Mermaid diagrams-as-code, syntax highlighting (highlight.js), and raw inline SVG markup
- **Browser Extension (Rune Chat)** — Chrome and Firefox side-panel extension for contextual AI chat and seamless note sync
- **Command Policy** — Three modes: `allowlist` (default; whitelist only), `confirm` (interactive prompts), `unrestricted`
- **Skills System** — Load contextual abilities via `+skill_name` in prompts
- **Provider Registry** — GitHub Copilot (auto token refresh), OpenRouter (recommended), Google Gemini, any OpenAI-compatible
- **MCP Client & Server** — Stdio JSON-RPC client for external MCP servers + built-in HTTP MCP server endpoint (`POST /mcp`) for external agents
- **Streaming Output** — Interactive mode displays tokens incrementally as they arrive
- **Parallel Tool Calls** — Multiple independent tool calls execute concurrently
- **Context Window Management** — Auto-compact when context exceeds 85% of model limit
- **Vision / Image Input** — Multi-modal messages with text + images (base64 or URL)
- **Native Gemini Provider** — Google Gemini API with automatic message format conversion
- **Wildcard Domains** — `*.github.com` in allowed_domains matches all subdomains
- **Concourse CI** — Same binary acts as a resource type (`check`, `in`, `out`) via symlink
- **Trace Recording** — JSON trace files with sensitive info redaction
- **JSON Output** — `--json` flag for machine-readable output
- **Vim / Neovim Integration** — Native FIM ghost text completion and interactive commands (`:RuneAsk`, `:RuneEdit`, `:RuneStatus`, `:RuneLog`) built into the binary via `--features vim`
- **Non-Interactive Pipe Mode** — piped stdin runs once and exits; no interactive prompt loop
## Quick Start
```bash
# Build (single binary)
cargo build --release
# Interactive setup
./target/release/rune init

```
## MCP Client Configuration
Rune can connect to any number of external MCP servers (acting as an **MCP client**). Each server runs as a child process communicating over stdio JSON-RPC.
### Fields
| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `name` | string | — | **Required.** Unique identifier shown in `/tools` and `/info`. |
| `command` | string | — | **Required.** Executable to launch (resolved via `PATH`). |
| `args` | array | `[]` | Command-line arguments passed to the executable. |
| `env` | table | `{}` | Extra environment variables injected into the child process. |
| `timeout_secs` | integer | `30` | Per-call timeout in seconds. Set to `0` for no timeout. |
| `required` | bool | `false` | If `true`, Rune exits at startup when this server fails to connect. |
### Single MCP Server
```toml
[[mcp]]
name = "filesystem"
command = "npx"
args = ["-y", "@modelcontextprotocol/server-filesystem", "/home/user/docs"]
```
### Multiple MCP Servers
Repeat `[[mcp]]` for each server — TOML array-of-tables syntax:
```toml
[[mcp]]
name = "filesystem"
command = "npx"
args = ["-y", "@modelcontextprotocol/server-filesystem", "/home/user/docs"]
required = true
timeout_secs = 10
[[mcp]]
name = "github"
command = "npx"
args = ["-y", "@modelcontextprotocol/server-github"]
[mcp.env]
GITHUB_TOKEN = "ghp_your_token_here"
[[mcp]]
name = "zhtw-mcp"
command = "zhtw-mcp"
args = ["--stdio"]
required = false
timeout_secs = 60
```
### With Environment Variables
Use `[mcp.env]` (inline table notation) to inject secrets without hardcoding them in args:
```toml
[[mcp]]
name = "my-private-api"
command = "/usr/local/bin/my-mcp-server"
args = ["--port", "0"]
[mcp.env]
API_KEY = "secret"
BASE_URL = "https://api.example.com"
```
> **Note:** `[[mcp]]` configures Rune as an **MCP client** connecting to external servers.
> The built-in MCP server endpoint (`POST /mcp`) exposed by `rune notes` is separate and
> always available when running in serve mode.
### Environment Variables
| Variable | Description |
|----------|-------------|
| `RUNE_API_KEY` | LLM provider API key |
| `RUNE_PROVIDER` | Provider name (github-copilot, gemini, openai, openrouter, ollama, anthropic) |
| `RUNE_MODEL` | Model name |
| `RUNE_BASE_URL` | Provider base URL |
| `RUNE_POLICY_MODE` | Policy mode override (legacy; prefer `[policy] mode` in config) |
| `RUNE_LOG_LEVEL` | Log level |
| `RUNE_TRACE` | Enable trace (true/false) |
| `RUNE_CONTEXT_WINDOW` | Model context window in tokens (default: 128000) |
| `RUNE_COMPACT_THRESHOLD` | Auto-compact trigger fraction (default: 0.85) |
| `RUNE_COMPACT_KEEP_LAST` | Keep last N messages during auto-compact (default: 6) |
| `RUNE_JSON_OUTPUT` | JSON output mode (`true` / `false`, also accepts `1` / `0`) |
| `RUNE_SYSTEM_PROMPT` | Custom system prompt (replaces default; AGENTS.md still appended) |
| `RUNE_YES` | Auto-approve dangerous tool execution (`true` / `false`, also accepts `1` / `0`) |
## Zero-Trust Sandbox
Every tool invocation passes through up to 5 isolation layers:
```
┌─────────────────────────────────────────────┐
│ Layer 1: cgroups (memory + pids limits) │
│ Layer 2: net-guard (seccomp user notif) │
│ Layer 3: Seccomp BPF (syscall filter) │
│ Layer 4: Landlock (filesystem restriction) │
│ Layer 5: DNS allowlist (domain control) │
└─────────────────────────────────────────────┘
```
### Sandbox Demo
#### ✅ ALLOWED — Operations that succeed:
```
ᚱ› (read /etc/hostname)
⚙ read_file({"path": "/etc/hostname"})
✓ read_file...ok → "u"
ᚱ› (write to /tmp)
⚙ write_file({"path": "/tmp/test.txt", "content": "hello"})
✓ write_file...ok → "Written 5 bytes"
ᚱ› (run allowed command)
⚙ execute_cmd({"cmd": "echo hello"})
✓ execute_cmd...ok → "hello"
```
#### ❌ BLOCKED — Operations that fail:
```
ᚱ› (fetch non-allowed URL)
⚙ fetch_url({"url": "https://example.com"})
✗ BLOCKED: domain 'example.com' is not in allowed_domains
ᚱ› (run non-allowed command in allowlist mode)
⚙ execute_cmd({"cmd": "rm -rf /"})
✗ BLOCKED by policy: command 'rm' is not in allowed_commands
ᚱ› (read sensitive file)
⚙ read_file({"path": "/etc/shadow"})
✗ Permission denied (Landlock + user namespace)
ᚱ› (ptrace attempt inside sandbox)
→ Seccomp BPF: Operation not permitted
```
### Command Policy
| Mode | Behavior | Default for |
|------|----------|-------------|
| `allowlist` | Auto-execute within allowlist, block everything else | Default for all modes (Interactive CLI, Pipe mode, Concourse CI) |
| `confirm` | Prompt Y/n before dangerous tool calls; blocked resources trigger Add-to-allowlist prompts | Opt-in via `mode = "confirm"` |
| `unrestricted` | All policy checks skipped | Opt-in via `--unrestricted` flag |
**Defaults by context:**
- **Interactive CLI** (`rune`): `allowlist` (default) — auto-executes within allowlist; use `mode = "confirm"` for interactive prompts
- **Pipe mode** (`echo "..." \| rune`): `allowlist` — runs within configured allowlists
- **Concourse CI** (check/get/put): `allowlist` — enforces sandbox policy from pipeline YAML
Override with `--unrestricted` flag or `RUNE_POLICY_MODE=unrestricted` env var:
```toml
[policy]
mode = "unrestricted"
```
In Concourse CI pipelines, set via `source.policy.mode`:
```yaml
resources:
- name: my-agent
type: rune-agent
source:
api_key: ((key))
policy:
mode: unrestricted
```
## JSON Output Mode
```bash
echo "What is 2+2?" | rune --json
```
```json
{"answer":"4","steps":1,"tokens":348,"tools_used":[]}
```
## CLI Flags
```bash
# Machine-readable output
rune --json
# Skip confirm prompts for dangerous tools
rune --yes
# or
rune -y
# Mount specified folder over real HOME in sandbox (defaults to CWD if omitted)
rune -H
# or specify a path
rune -H /path/to/home
# Mount path(s) or file(s) as Read-Write in sandbox (defaults to CWD if omitted, repeatable)
rune -M
# or specify paths
rune -M ./dist -M ./coverage.json
# Mount path(s) or file(s) as Read-Only in sandbox (defaults to CWD if omitted, repeatable)
rune -m
# or specify paths
rune -m ~/.rustup -m ~/.gitconfig
```
## Pipe / Non-Interactive Mode
When stdin is piped into Rune, it runs in one-shot non-interactive mode:
```bash
echo "Get weather for Taoyuan from wttr.in" | rune --json --yes
```
Behavior in pipe mode:
- reads all stdin as a single prompt
- does **not** enter the interactive prompt loop
- exits immediately after one run
- if confirm mode would require approval, Rune stops with an error unless `--yes` is provided
## Skills
```
skills/
├── sysadmin/
│ └── SKILL.md
└── launchpad/
├── SKILL.md
└── references/
```
Use `+skill_name` in prompts:
```
ᚱ› Use +sysadmin skill. Check disk usage.
📚 Loaded skill: sysadmin
```
For scripting, combine skills with pipe mode:
```bash
echo "Use +sysadmin skill. Check disk usage." | rune --json --yes
```
## Rune Notes (AI-Native Data Exchange Hub)
Rune Notes is a responsive web app and an **AI-native Markdown system**, acting as the central **Data Exchange Hub**. It ships as a **single self-contained executable** — one process serves the web UI, the MCP endpoint, and the REST API.
All clients converge on plain Markdown files stored on the local filesystem as the **single source of truth**.
```bash
# Start Rune Notes server
rune notes --bind 0.0.0.0 --port 9527
```

### Key Highlights
- **Single Self-Contained Binary** — Zero external runtime, no VM or dependency chain. Self-contained on Linux with kernel-level isolation.
- **Universal Client Access**:
- **External Agents over MCP**: Antigravity, OpenClaw, Hermes Agent, GitHub Copilot, and OpenCode interact directly with notebook workspaces via the built-in MCP endpoint (`POST /mcp`).
- **First-Party Browser Extension**: **Rune Chat** (Chrome and Firefox) connects via REST API from the browser side-panel to chat about the active webpage and update notes in real-time.
- **In-App Native**: Built-in AI chat agent and human editor manipulate the same Markdown files in place.
- **Rich Markdown Engine**:
- **LaTeX / KaTeX Math** — Inline `$E=mc^2$` and display blocks `$$\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}$$`.
- **Mermaid Diagrams** — Flowcharts, sequence diagrams, and class diagrams rendered directly from text.
- **Raw Inline SVG** — Directly embed `<svg>` markup for custom visual diagrams without image hosting.
- **Syntax Highlighting** — Fenced code blocks with automatic language styling.
- **Adaptive Responsive Layout**:
- **Desktop**: 3-column view (file navigator, Markdown editor, and AI chat side by side).
- **Tablet**: Collapsible panels and touch-friendly targets.
- **Mobile**: Single-column adaptive view with fast switching.
- **Real-Time Collaboration** — Server-Sent Events (SSE) stream AI tokens, user presence, and file changes live.
### Browser Extension (Rune Chat)
Rune includes a first-party browser extension located in `browser-extension/`:
- **Side Panel UI** — Chat with your Rune server about the webpage you're viewing without leaving the tab.
- **Chrome MV3 & Firefox MV3** — Shared codebase using WebExtension standards.
- **OAuth 2.1 PKCE** — Secure authentication flow directly to your Rune Notes server.
- **Build**:
```bash
node browser-extension/build.js
# Produces dist/chrome/ and dist/firefox/
# Zipped automatically in CI as rune-extension-chrome.zip & rune-extension-firefox.zip
```
### Authentication & Providers
Rune Notes supports three authentication strategies:
1. **GitHub OAuth 2.0** — Easy login with role mapping via usernames or organizations/teams (`org:my-org/team`).
2. **OAuth 2.0 / OIDC** — Connect to Google, Okta, Authentik, Keycloak, or any standard OIDC identity provider.
3. **Local Static Password** — Standalone accounts for air-gapped or home-server environments.
**Supported LLM Providers:** OpenRouter (recommended), GitHub Copilot (auto token refresh), Google Gemini, and OpenAI-compatible endpoints.
### Configuration
```toml
[notes]
port = 9527
bind = "0.0.0.0"
thinking = "high"
# GitHub OAuth 2.0 Login
[notes.github]
client_id = "your_github_client_id"
client_secret = "your_github_client_secret"
admins = ["fourdollars", "org:my-org/ops"]
users = ["org:my-org"]
guests = []
# Local Static Password Login
[notes.local]
admins = ["admin:admin123"]
users = ["user:user123"]
guests = ["guest:guest123"]
# Third-party OAuth2/OIDC Login (multiple providers)

### Public Pages
Admin can toggle visibility (public/private) for individual notes and files. When set to public, anyone can view rendered Markdown without authentication at:
- **Index:** `http://host:port/notes/` — lists all public notes
- **Preview:** `http://host:port/notes/{note}/{filename}` — rendered Markdown page with KaTeX math, Mermaid diagrams, and syntax highlighting
- **Raw content:** `http://host:port/raw/{note}/{filename}`
## Concourse CI Resource Type
### Quick Start — Weather Check
The simplest possible pipeline using Rune as a Concourse CI resource type:
```yaml
resource_types:
- name: rune-agent
type: registry-image
source:
repository: ghcr.io/fourdollars/rune
tag: latest
resources:
- name: weather
type: rune-agent
check_every: 1h
source:
api_key: ((copilot-pat))
model: gpt-4o-mini
prompt: "Fetch the weather for Taoyuan from wttr.in using curl."
policy:
allowed_commands: ["curl"]
allowed_domains: ["wttr.in"]
jobs:
- name: weather-check
plan:
- get: weather
trigger: true
- task: show
config:
platform: linux
image_resource:
type: registry-image
source: { repository: ghcr.io/fourdollars/rune, tag: latest }
inputs: [{name: weather}]
run:
path: sh
args: [-c, "cat weather/response.txt"]
```
That's it! Rune handles:
- AI prompt → tool selection → sandboxed execution → response
- Network filtering (only `wttr.in` allowed)
- Automatic version tracking (content hash)
### Detailed Usage
Rune acts as a content-aware Concourse CI resource type. **All three resource steps (`check` / `in` / `out`) run through the same sandboxed Rune agent pipeline as pipe mode.**
- `check` executes the prompt, hashes the final answer, and returns `{"ref":"sha256:..."}`
- `in` re-executes the prompt and writes `payload.json` + `response.txt`
- `out` executes `params.prompt` and returns a new version
When tool usage is needed, configure sandbox allowlists in the resource source (domains, paths, commands via Rune policy).
```yaml
resource_types:
- name: rune-agent
type: registry-image
source:
repository: ghcr.io/fourdollars/rune
tag: latest
resources:
- name: ai-news
type: rune-agent
source:
api_key: ((copilot_key)) # ghu_/ghp_ auto-refreshed
model: gpt-4o-mini
prompt: "List top 3 trending AI topics today. One line each."
policy:
allowed_commands: ["curl", "ls", "cat"]
allowed_domains: ["news.google.com", "api.github.com"]
jobs:
- name: news-digest
plan:
- get: ai-news # triggers when content changes
trigger: true
- task: translate
config:
platform: linux
image_resource:
type: registry-image
source: { repository: ghcr.io/fourdollars/rune, tag: latest }
inputs: [{name: ai-news}]
run:
path: sh
args: [-c, "cat ai-news/response.txt"]
- name: ask-ai
plan:
- put: ai-news
params:
prompt: "Translate to zh-TW: AI is transforming healthcare."
```
### Resource Lifecycle
| Mode | Behavior |
|------|----------|
| `check` | Run sandboxed agent on `source.prompt` → sha256(final answer) → version `{"ref":"sha256:..."}` |
| `in` (get) | Run sandboxed agent again → write `payload.json` + `response.txt` to dest dir |
| `out` (put) | Run sandboxed agent on `params.prompt` → return version + print response to build log |
### Supported Providers
GitHub Copilot tokens (`ghu_`/`ghp_`) are auto-detected and refreshed. Google Gemini (`AIza*` keys) uses the native Gemini API format. OpenAI, OpenRouter, Ollama, Anthropic, and any OpenAI-compatible endpoint work via `base_url`. Use `--provider <name>` or `provider = "..."` in config to override auto-detection.
### Output Files (get step)
| File | Content |
|------|---------|
| `payload.json` | `{prompt, response, ref, model, timestamp}` |
| `response.txt` | Raw LLM response text |
