Rampart is a runtime policy engine for AI coding agents. Every tool call — bash commands, file reads, file writes, HTTP fetches — is evaluated against your YAML policies before it executes. Dangerous calls are blocked in microseconds. Everything is written to a hash-chained audit trail. Ambiguous calls can be held for human approval.

It works in `--dangerously-skip-permissions` mode. [Full setup guide →](https://docs.rampart.sh/getting-started/quickstart/)

### Get started in one command

```bash

# Install and set up in one command:

curl -fsSL https://rampart.sh/install | bash

```

`rampart quickstart` auto-detects Claude Code, Cursor, or Windsurf, installs `rampart serve` as a boot service, configures hooks, and runs a health check. Done.

Or set up manually:

```bash

rampart serve install                 # Install background service (saves token to ~/.rampart/token)

rampart setup claude-code             # Wire up Claude Code hooks

```

Once running, every command Claude executes goes through Rampart's policy engine first:

```

✅ 14:23:01  exec  "npm test"                          [allow-dev]

✅ 14:23:03  read  ~/project/src/main.go                [default]

🔴 14:23:05  exec  "rm -rf /tmp/*"                      [block-destructive]

🟡 14:23:08  exec  "curl https://api.example.com"       [log-network]

👤 14:23:10  exec  "kubectl apply -f prod.yaml"         [require-approval]

```

## Install

```bash

# One-line install (macOS & Linux, no sudo required):

curl -fsSL https://rampart.sh/install | bash

```

Or pick your preferred method:

```bash

# Homebrew (macOS and Linux)

brew install peg/rampart/rampart

# Go install (requires Go 1.24+)

go install github.com/peg/rampart/cmd/rampart@latest

# Or download a binary from GitHub Releases

# https://github.com/peg/rampart/releases

```

> **Tip:** The curl installer drops the binary in `~/.local/bin` and runs `rampart quickstart` automatically.

> Pin a version with `RAMPART_VERSION=v0.3.0 curl -fsSL https://rampart.sh/install | bash`.

>

> Run `rampart version` to confirm.

After installing the binary, run `rampart quickstart` to set everything up in one shot, or follow the manual steps below.

---

## Claude Code integration

Native integration through Claude Code's hook system:

```bash

# Start the background service (installs to systemd/launchd, saves token to ~/.rampart/token)

rampart serve install

# Wire up Claude Code hooks (auto-discovers the service — no env vars needed)

rampart setup claude-code

```

Every Bash command, file read, and file write goes through Rampart's policy engine before execution. Blocked commands never run.

Then just use Claude Code normally:

```bash

claude

```

See what's happening in real time:

```bash

rampart watch

```

## Wrap any agent

For agents without a hook system, `wrap` sets `$SHELL` to a policy-checking shim. Works with any agent that reads the `$SHELL` environment variable (Aider, OpenCode, Continue, Cline, and more):

```bash

rampart wrap -- aider

rampart wrap -- opencode

rampart wrap -- python my_agent.py

```

## Protect any process (LD_PRELOAD)

For agents with no hook system and no `$SHELL` support, `preload` intercepts exec-family syscalls at the OS level. This is the universal fallback — it works with **any** dynamically-linked process:

```bash

# Protect Codex CLI (no hooks, no $SHELL — preload is the only way)

rampart preload -- codex

# Protect any Python agent

rampart preload -- python my_agent.py

# Protect any Node.js agent

rampart preload -- node agent.js

# Monitor mode (log only, don't block)

rampart preload --mode monitor -- risky-tool

```

Preload intercepts `execve`, `execvp`, `system()`, `popen()`, and `posix_spawn()` — every way a process can spawn a command. Each call gets evaluated against your policy before executing. Denied calls return `EPERM`.

**Requires:** `librampart.so` (Linux) or `librampart.dylib` (macOS) installed to `~/.rampart/lib/`. Build from `preload/` or download from releases.

**Platform notes:**

- **Linux:** Works with all dynamically-linked binaries (~95% coverage)

- **macOS:** Works with Homebrew, nvm, pyenv, cargo binaries. Blocked by SIP for `/usr/bin/*` (but AI agents don't live there)

See [`preload/README.md`](preload/README.md) for build instructions and details.

---

## Protect MCP servers

Drop-in proxy between your agent and any MCP server. Evaluates every `tools/call` against your policies:

```bash

# Instead of connecting directly to an MCP server:

rampart mcp -- npx @modelcontextprotocol/server-filesystem /path

```

In your MCP config (Claude Code, Cursor, etc.):

```json

{

  "mcpServers": {

    "filesystem": {

      "command": "rampart",

      "args": ["mcp", "--", "npx", "@modelcontextprotocol/server-filesystem", "."]

    }

  }

}

```

Denied tool calls return a JSON-RPC error — the MCP server never sees them. Safe calls pass through transparently. Tools with destructive keywords (delete, destroy, remove) are blocked out of the box.

### Auto-generate policies from MCP servers

Don't write policies from scratch — scan an MCP server's tool list and generate a deny-by-default policy:

```bash

rampart mcp scan -- npx @modelcontextprotocol/server-filesystem .

```

Review, customize, deploy. Each tool becomes an explicit rule you can allow or deny.

---

## Quick start

```bash

# One-shot setup: detects your agent, installs the service, wires hooks, runs health check

rampart quickstart

# Or set up for a specific agent

rampart setup claude-code     # Claude Code native hooks

rampart wrap -- aider         # Any agent that reads $SHELL

# Test a command against your policies without running it

echo '{"tool_name":"Bash","tool_input":{"command":"rm -rf /"}}' | rampart hook

# → {"hookSpecificOutput":{"permissionDecision":"deny","permissionDecisionReason":"Rampart: Destructive command blocked"}}

# Or test directly

rampart test "rm -rf /"

```

Three built-in profiles:

| Profile | Default | Use case |

|---------|---------|----------|

| `standard` | allow | Block dangerous, watch suspicious, allow the rest |

| `paranoid` | deny | Explicit allowlist for everything |

| `yolo` | allow | Log-only, no blocking |

---

## Writing policies

Policies are YAML. Glob matching, hot-reload on file change.

```yaml

version: "1"

default_action: allow

policies:

  - name: block-destructive

    match:

      tool: ["exec"]

    rules:

      - action: deny

        when:

          command_matches: ["rm -rf *", "mkfs.*", "dd if=*", ":(){ :|:& };:"]

        message: "Destructive command blocked"

  - name: block-credential-reads

    priority: 1

    match:

      tool: ["read"]

    rules:

      - action: deny

        when:

          path_matches: ["**/.ssh/id_*", "**/.aws/credentials", "**/.env"]

        message: "Credential access blocked"

  - name: block-exfil

    match:

      tool: ["fetch"]

    rules:

      - action: deny

        when:

          domain_matches: ["*.ngrok-free.app", "*.requestbin.com", "webhook.site"]

        message: "Exfiltration domain blocked"

```

**Evaluation:** Deny always wins. Lower priority number = evaluated first. Four actions: `deny`, `require_approval`, `watch`, `allow`. (`log` is a deprecated alias for `watch` — update your policies if you use it.)

### Project-local policies

Drop `.rampart/policy.yaml` in any git repo to add project-specific rules on top of your global policy. Commit it so every team member gets the same rules automatically — zero per-developer configuration.

```bash

# Scaffold a project policy in the current repo

rampart init --project

```

Or create it manually:

```bash

mkdir -p .rampart && cat > .rampart/policy.yaml << 'EOF'

version: "1"

policies:

  - name: myapp-no-prod-migrations

    match:

      tool: exec

    rules:

      - action: deny

        when:

          command_matches: ["*migrate*--env=production*"]

        message: "Production migrations require human review"

EOF

git add .rampart/policy.yaml && git commit -m "Add Rampart project policy"

```

Global policy always takes precedence for `default_action`. Set `RAMPART_NO_PROJECT_POLICY=1` to skip project policy loading.

Run `rampart doctor` in any repo — it reports whether a project policy is found.

### Session identity

Audit events are tagged with the current session, auto-detected from git as `reponame/branch` (e.g. `myapp/main`). Use `session_matches` in policy rules to apply stricter rules to specific repos or branches:

```yaml

rules:

  - action: require_approval

    when:

      session_matches: ["myapp/main", "myapp/production"]

    message: "Exec on production branch requires approval"

```

Override the auto-detected label with `RAMPART_SESSION=my-label`.

---

## Approval flow

For the grey area — commands that need a human to decide:

```yaml

policies:

  - name: production-deploys

    match:

      tool: ["exec"]

    rules:

      - action: require_approval

        when:

          command_matches: ["kubectl apply *", "terraform apply *"]

        message: "Production deployment requires approval"

```

Pending approvals expire after **1 hour** by default (configurable with `--approval-timeout`).

How approval reaches you depends on your environment:

```mermaid

graph LR

    PE[Policy Engine] -->|require_approval| D{Environment}

    D -->|Claude Code| CC["Native prompt
(ask hook)"]

    D -->|MCP Client| MCP["Block & wait

    D -->|OpenClaw| OC["Chat message

    style R fill:#238636,stroke:#fff,color:#fff

```

```bash

rampart pending                # What's waiting

rampart approve abc123         # Let it through

rampart deny abc123            # Block it

```

---

## Preflight API

Check if a call would be allowed without executing it:

```bash

curl -s localhost:9090/v1/preflight/exec \

  -H "Authorization: Bearer $TOKEN" \

  -H "Content-Type: application/json" \

  -d '{"agent":"a","session":"s","params":{"command":"rm -rf /"}}'

# → {"allowed":false,"decision":"deny","matched_policies":["block-destructive"]}

```

No side effects. For agents that plan before acting.

---

## Audit trail

Every tool call is logged to hash-chained JSONL. Each entry includes a SHA-256 hash of the previous entry — tamper with any record and the chain breaks.

```bash

rampart audit tail --follow     # Stream events

rampart audit verify            # Check chain integrity

rampart audit stats             # Decision breakdown

rampart audit search            # Query by tool, agent, decision, time range

```

Why hash-chained: in regulated environments, you need to prove what your agent did. A hash chain means no one can edit history without detection.

---

## Live dashboard

```bash

rampart watch           # TUI — live colored event stream in your terminal

```

When `rampart serve` is running, a web dashboard is also available at **http://localhost:9090/dashboard/** (or **http://localhost:18275/dashboard/** if installed via `rampart serve install`).

The dashboard has three tabs:

- **Active** — live stream of tool calls; approve or deny queued requests in real time

- **History** — browse past tool calls with filtering by tool, decision, and time

- **Policy** — view loaded rules; test commands against your policy with the **"Try a command"** REPL before they ever run

Supports dark and light theme. No extra setup needed — it's built into `rampart serve`.

```

```

---

## Webhook notifications

Get real-time alerts when Rampart blocks something. Add a `notify` section to your policy file:

```yaml

version: "1"

default_action: allow

notify:

  url: "https://discord.com/api/webhooks/your/webhook"

  # Or Slack: "https://hooks.slack.com/services/your/webhook"

  on: ["deny"]  # Only notify on denied commands (options: deny, watch)

policies:

  # ... your policies

```

Rampart sends a JSON payload to your webhook URL whenever a matching event occurs:

```json

{

  "timestamp": "2026-02-11T21:03:38Z",

  "decision": "deny",

  "tool": "exec",

  "command": "rm -rf /tmp/*",

  "policy": "protect-sys",

  "message": "Destructive command blocked",

  "agent": "claude-code",

  "session": "myapp/main"

}

```

Works with Discord webhooks, Slack incoming webhooks, or any HTTP endpoint that accepts POST requests.

---

## SIEM integration

Send audit events to your existing security stack. Three output formats, works with any SIEM:

```bash

# RFC 5424 syslog (Wazuh, QRadar, ArcSight, LogRhythm, Sentinel)

rampart serve --syslog localhost:514

# Common Event Format (Splunk, QRadar, ArcSight, Exabeam)

rampart serve --syslog localhost:514 --cef

# CEF to file (when you don't have a syslog collector)

rampart serve --cef

```

All three outputs run alongside the default JSONL audit trail — you don't lose anything by enabling SIEM output.

**Wazuh users**: See [`docs/guides/wazuh-integration.md`](docs/guides/wazuh-integration.md) for a complete setup guide with custom decoder, alerting rules, and FIM recommendations for AI agent hosts.

---

## Webhook actions

Delegate allow/deny decisions to an external service — LLM-based intent verification, Slack approval bots, custom logic:

```yaml

rules:

  - action: webhook

    when:

      command_matches: ['*production*']

    webhook:

      url: 'http://localhost:8090/verify'

      timeout: 5s

      fail_open: true

```

The webhook receives the full tool call context and returns `{"decision": "allow"}` or `{"decision": "deny", "reason": "..."}`. Fail-open by default so a down webhook doesn't break your agent.

**Reference implementation**: See [`rampart-verify`](https://github.com/peg/rampart-verify) — an optional sidecar that uses LLMs (gpt-4o-mini, Claude Haiku, or local Ollama) to classify ambiguous commands. Pattern matching handles 95% of decisions for free; the sidecar reviews the rest at ~$0.0001/call.

---

## Integration

### HTTP proxy

Anything that can make HTTP requests works with Rampart. Point your agent's tool calls at the proxy:

| Method | Endpoint | Purpose |

|--------|----------|---------|

| `POST` | `/v1/tool/{toolName}` | Evaluate and execute |

| `POST` | `/v1/preflight/{toolName}` | Dry-run check |

| `GET` | `/v1/approvals` | Pending approvals |

| `POST` | `/v1/approvals/{id}/resolve` | Approve or deny |

| `GET` | `/healthz` | Health check |

### Framework examples

```python

# Python (LangChain, CrewAI, any framework)

response = requests.post("http://localhost:9090/v1/tool/exec",

    headers={"Authorization": f"Bearer {token}"},

    json={"agent": "my-agent", "session": "s1", "params": {"command": cmd}})

if response.json()["decision"] == "deny":

    return f"Blocked: {response.json()['message']}"

```

### OpenClaw

For [OpenClaw](https://github.com/openclaw/openclaw) users — one command sets up a shell shim and background service:

```bash

rampart setup openclaw

```

This covers all `exec` tool calls. For full file tool coverage (Read, Write, Edit), run:

```bash

rampart setup openclaw --patch-tools

```

This patches OpenClaw's Read, Write, Edit, and Grep tools to check Rampart before file operations. Requires write access to the OpenClaw installation directory (typically needs `sudo` for global npm installs).

Supports recent OpenClaw versions with shell shim capabilities.

⚠️ **Re-run after OpenClaw upgrades** — the patch modifies files in `node_modules` that get replaced on update. Between upgrade and re-patch, file tools bypass Rampart (exec shim remains active).

Works on Linux (systemd) and macOS (launchd).

---

## Performance

Policy evaluation in single-digit microseconds:

| Command | Decision | Time |

|---------|----------|------|

| `rm -rf /` | deny | 8µs |

| `sudo reboot` | watch | 6µs |

| `.ssh/id_rsa` read | deny | 3µs |

| `git status` | allow | 4µs |

| `curl ngrok.io` | deny | 3µs |

The proxy adds negligible latency. Agents wait seconds for LLM responses — a few microseconds of policy evaluation is invisible.

---

## Security recommendations

**Don't run your AI agent as root.** If the agent runs as root, no user separation can protect policy files or audit logs — root can read everything. Run your agent framework (OpenClaw, Claude Code, etc.) as an unprivileged user.

**Run `rampart serve` as a separate user.** If Rampart runs as the same user as your AI agent, the agent can read audit logs and modify policy files. A dedicated `rampart` user prevents this:

```bash

# Create a service account

sudo useradd -r -s /usr/sbin/nologin rampart

# Move config and audit to the new user

sudo mkdir -p /etc/rampart /var/lib/rampart/audit

sudo cp ~/.rampart/policies/*.yaml /etc/rampart/

sudo chown -R rampart:rampart /etc/rampart /var/lib/rampart

sudo chmod 700 /etc/rampart /var/lib/rampart/audit

# Run serve as the rampart user

# (update your systemd service with User=rampart)

rampart serve --config /etc/rampart/standard.yaml --audit-dir /var/lib/rampart/audit

```

The agent communicates with Rampart over HTTP on localhost — no file access needed. This means:

- **Audit logs** are protected from agent tampering or credential harvesting

- **Policy files** can't be modified by the agent to weaken its own rules

- **The agent loses zero capability** — it still executes commands normally

For single-user or development setups, running as the same user works fine. The separation matters most in production where agents run unsupervised.

For a full discussion of what Rampart does and doesn't protect against, see [`docs/THREAT-MODEL.md`](docs/THREAT-MODEL.md).
