# XecGuard
|
||||
|
||||
Use [XecGuard](https://www.cycraft.com/) (CyCraft) to protect your LLM applications with multi-policy scanning (prompt injection, harmful content, PII, system-prompt enforcement, skills protection) and RAG context grounding validation. XecGuard is a cloud-hosted AI security gateway — there are no self-hosting requirements.
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Define Guardrails on your LiteLLM config.yaml
|
||||
|
||||
```yaml showLineNumbers title="config.yaml"
|
||||
model_list:
|
||||
- model_name: gpt-4
|
||||
litellm_params:
|
||||
model: openai/gpt-4
|
||||
api_key: os.environ/OPENAI_API_KEY
|
||||
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-guard"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
api_base: os.environ/XECGUARD_API_BASE # Optional
|
||||
policy_names: # Optional — defaults to System Prompt Enforcement + Harmful Content Protection
|
||||
- Default_Policy_SystemPromptEnforcement
|
||||
- Default_Policy_HarmfulContentProtection
|
||||
```
|
||||
|
||||
#### Supported values for `mode`
|
||||
|
||||
- `pre_call` — Run **before** the LLM call to validate **user input**
|
||||
- `post_call` — Run **after** the LLM call to validate **model output** (also runs context grounding when RAG documents are provided)
|
||||
- `during_call` — Run **in parallel** with the LLM call for input validation
|
||||
- `logging_only` — Run as an **observe-only** callback; records scan decisions without blocking
|
||||
|
||||
### 2. Set Environment Variables
|
||||
|
||||
```shell
|
||||
export XECGUARD_API_KEY="xgs_<your-service-token>"
|
||||
export XECGUARD_API_BASE="https://api-xecguard.cycraft.ai" # Optional, this is the default
|
||||
export XECGUARD_BLOCK_ON_ERROR="true" # Optional, fail-closed by default
|
||||
```
|
||||
|
||||
### 3. Start LiteLLM Gateway
|
||||
|
||||
```shell
|
||||
litellm --config config.yaml --detailed_debug
|
||||
```
|
||||
|
||||
### 4. Test request
|
||||
|
||||
<Tabs>
|
||||
<TabItem label="Blocked Request" value="blocked">
|
||||
|
||||
Test input validation with a prompt-injection / system-prompt bypass attempt:
|
||||
|
||||

|
||||
],
|
||||
"guardrails": ["xecguard-guard"]
|
||||
}'
|
||||
```
|
||||
|
||||
Expected response on policy violation:

|
||||

```
|
||||
|
||||
### Required
|
||||
|
||||
| Parameter | Description |
|
||||
|-----------|-------------|
|
||||
| `api_key` | XecGuard **Service Token** (prefix `xgs_`). Falls back to `XECGUARD_API_KEY` env var. |
|
||||
|
||||
### Optional
|
||||
|
||||
| Parameter | Default | Description |
|
||||
|-----------|---------|-------------|
|
||||
| `api_base` | `https://api-xecguard.cycraft.ai` | XecGuard API base URL. Falls back to `XECGUARD_API_BASE` env var. |
|
||||
| `xecguard_model` | `xecguard_v2` | XecGuard scanning model identifier. |
|
||||
| `policy_names` | `["Default_Policy_SystemPromptEnforcement", "Default_Policy_HarmfulContentProtection"]` | Policies applied on each scan. See [Available Policies](#available-policies) below. |
|
||||
| `block_on_error` | `true` | Fail-closed by default. Set to `false` for fail-open behaviour (requests pass through when the XecGuard API is unreachable). |
|
||||
| `grounding_strictness` | `BALANCED` | Either `BALANCED` or `STRICT`. Controls how strictly the `/grounding` endpoint evaluates response fidelity to supplied context documents. |
|
||||
| `default_on` | `false` | When `true`, the guardrail runs on every request without needing to specify it in the request body. |
|
||||
|
||||
## Available Policies
|
||||
|
||||
XecGuard ships with six built-in default policies. Select one or more via `policy_names`:
|
||||
|
||||
| Policy Name | Purpose |
|
||||
|-------------|---------|
|
||||
| `Default_Policy_SystemPromptEnforcement` | Ensures the user prompt stays within the tasks defined by the system prompt |
|
||||
| `Default_Policy_GeneralPromptAttackProtection` | Detects prompt injection, prompt extraction, encoded bypass attempts |
|
||||
| `Default_Policy_ContentBiasProtection` | Detects discrimination, harassment, harmful stereotypes |
|
||||
| `Default_Policy_HarmfulContentProtection` | Detects harmful speech/semantics violating public order and good morals |
|
||||
| `Default_Policy_SkillsProtection` | Detects malicious content in AI-agent skill files |
|
||||
| `Default_Policy_PIISensitiveDataProtection` | Detects personally identifiable information (PII) |
|
||||
|
||||
:::info
|
||||
The wildcard form `policy_names: ["*"]` is supported by the XecGuard API but requires your Service Token to be pre-bound to at least one policy in the XecGuard console.
|
||||
:::
|
||||
|
||||
## Context Grounding (RAG)
|
||||
|
||||
When scanning in `post_call` mode, XecGuard can additionally validate the assistant's response against reference documents via the `/grounding` endpoint. This catches hallucinations and factual drift in RAG applications.
|
||||
|
||||
Supply grounding documents at request time via the `metadata.xecguard_grounding_documents` field. Each document is `{document_id, context}`:
|
||||
|
||||
```shell
|
||||
curl -i http://0.0.0.0:4000/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "gpt-4",
|
||||
"messages": [
|
||||
{"role": "user", "content": "What nationality was Peggy Seeger?"}
|
||||
],
|
||||
"guardrails": ["xecguard-guard"],
|
||||
"metadata": {
|
||||
"xecguard_grounding_documents": [
|
||||
{
|
||||
"document_id": "peggy_seeger_bio",
|
||||
"context": "Peggy Seeger (born June 17, 1935) is an American folk singer."
|
||||
}
|
||||
]
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
If the assistant's response contradicts or is unsupported by the provided documents, the request is blocked with a grounding violation (`CONFLICT`, `BASELESS`, or `INCOMPLETE`):
|
||||
|
||||
```json
|
||||
{
|
||||
"error": {
|
||||
"message": "Blocked by XecGuard grounding: rules=[CONFLICT] trace_id=fabcde7890123456abcdef1234567829 rationale=Response states Peggy Seeger was British, but the document indicates she is American.",
|
||||
"type": "None",
|
||||
"param": "None",
|
||||
"code": "400"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Grounding only runs when:
|
||||
- `mode` includes `post_call`
|
||||
- `metadata.xecguard_grounding_documents` is a non-empty list
|
||||
- The messages contain both a user prompt and an assistant response
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Fail-Open Mode
|
||||
|
||||
By default XecGuard operates in **fail-closed** mode — if the API is unreachable, the request is blocked. Set `block_on_error: false` to allow requests through when the guardrail API fails:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-failopen"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
block_on_error: false
|
||||
```
|
||||
|
||||
### Input + Output Pipeline
|
||||
|
||||
Apply one guardrail for input validation and another for output scanning + grounding:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-input"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
policy_names:
|
||||
- Default_Policy_GeneralPromptAttackProtection
|
||||
- Default_Policy_SystemPromptEnforcement
|
||||
|
||||
- guardrail_name: "xecguard-output"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "post_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
policy_names:
|
||||
- Default_Policy_HarmfulContentProtection
|
||||
- Default_Policy_PIISensitiveDataProtection
|
||||
grounding_strictness: "STRICT"
|
||||
```
|
||||
|
||||
### Always-On Protection
|
||||
|
||||
Enable the guardrail for every request without specifying it per-call:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-guard"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
default_on: true
|
||||
```
|
||||
|
||||
### Logging-Only Mode
|
||||
|
||||
Observe scan decisions without blocking — useful for shadow-mode deployment before enforcement:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-monitor"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "logging_only"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
```
|
||||
|
||||
Scan results are attached to the standard logging payload (`standard_logging_guardrail_information`) and surface in Langfuse / DataDog / OTEL without ever blocking a request.
|
||||
|
||||
## Full Conversation History
|
||||
|
||||
XecGuard always receives the **full conversation history** — system, user, and assistant messages — for both input and response scans. This is required for policies such as `Default_Policy_SystemPromptEnforcement` to work correctly. There is no configuration option to disable this behaviour; the framework-wide `skip_system_message_in_guardrail` setting is intentionally ignored for XecGuard.
|
||||
|
||||
## Error Handling
|
||||
|
||||
**Missing API Credentials:**
|
||||
```
|
||||
XecGuardMissingCredentials: XecGuard API key is required.
|
||||
Set XECGUARD_API_KEY in the environment or pass api_key in the guardrail config.
|
||||
```
|
||||
|
||||
**API Unreachable (fail-closed, default):**
|
||||
The request is blocked and a `GuardrailRaisedException` is raised.
|
||||
|
||||
**API Unreachable (fail-open, `block_on_error: false`):**
|
||||
The request passes through unchanged and a warning is logged.

# LiteLLM Plugin Architecture
|
||||
|
||||
Plugins let external services appear as selectable modes in the litellm UI sidebar alongside the AI Gateway.
|
||||
|
||||
---
|
||||
|
||||
## Quick start
|
||||
|
||||
### 1. Configure the plugin
|
||||
|
||||
Add a `plugins` block to your litellm `config.yaml`:
|
||||
|
||||
```yaml
|
||||
general_settings:
|
||||
master_key: sk-...
|
||||
plugins:
|
||||
- name: my-plugin # unique identifier (no spaces)
|
||||
display_name: My Plugin # shown in the UI dropdown
|
||||
url: "https://my-plugin.example.com"
|
||||
plugin_key: "sk-..." # plugin's own auth credential
|
||||
```
|
||||
|
||||
`plugin_key` is injected as `Authorization: Bearer <plugin_key>` on every
|
||||
request proxied through `/plugin-proxy/my-plugin/*`. The caller's litellm
|
||||
credential is stripped before forwarding so the plugin never receives a live
|
||||
litellm API key.
|
||||
|
||||
### 2. Implement two endpoints on your service
|
||||
|
||||
| Endpoint | Method | Purpose |
|
||||
|---|---|---|
|
||||
| `GET /api/plugin-manifest` | public | Returns plugin metadata for the UI |
|
||||
| `POST /api/plugin-auth` | public | Decrypts the identity claim for seamless sign-in |
|
||||
|
||||
#### `GET /api/plugin-manifest`
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "my-plugin",
|
||||
"display_name": "My Plugin",
|
||||
"version": "1.0.0",
|
||||
"nav_items": [
|
||||
{ "key": "home", "label": "Home", "icon": "HomeOutlined", "path": "/" },
|
||||
{ "key": "reports", "label": "Reports", "icon": "BarChartOutlined", "path": "/reports" }
|
||||
],
|
||||
"capabilities": ["reports", "data"]
|
||||
}
|
||||
```
|
||||
|
||||
#### `POST /api/plugin-auth`
|
||||
|
||||
Receives `{ "session_claim": "<fernet-ciphertext>" }`.
|
||||
|
||||
The proxy never shares `LITELLM_SALT_KEY` with your plugin. Each plugin is
|
||||
provisioned with its own dedicated key, derived as
|
||||
`HMAC-SHA256(LITELLM_SALT_KEY, plugin_name)`. Compute it once on the proxy
|
||||
host and hand the result to your plugin as a secret (e.g. `PLUGIN_AUTH_KEY`):
|
||||
|
||||
```bash
|
||||
python -c 'import base64,hmac,hashlib,os; \
|
||||
print(base64.urlsafe_b64encode(hmac.new(os.environ["LITELLM_SALT_KEY"].encode(), b"my-plugin", hashlib.sha256).digest()).decode())'
|
||||
```
|
||||
|
||||
A compromised plugin holding only this scoped key cannot recover
|
||||
`LITELLM_SALT_KEY` or decrypt any other litellm secret.
|
||||
|
||||
Decrypt and validate the claim with that key:
|
||||
|
||||
```python
|
||||
import json, os, time
|
||||
from cryptography.fernet import Fernet
|
||||
|
||||
_CLAIM_TTL_SECONDS = 30
|
||||
|
||||
def plugin_auth(session_claim: str) -> dict:
|
||||
cipher = Fernet(os.environ["PLUGIN_AUTH_KEY"].encode())
|
||||
claim = json.loads(cipher.decrypt(session_claim.encode(), ttl=_CLAIM_TTL_SECONDS))
|
||||
if claim.get("plugin") != "my-plugin":
|
||||
raise ValueError("claim audience mismatch")
|
||||
if int(claim.get("exp", 0)) < int(time.time()):
|
||||
raise ValueError("claim expired")
|
||||
return claim
|
||||
```
|
||||
|
||||
The claim is `{ "plugin", "user_id", "user_role", "exp" }`; it carries no
|
||||
litellm bearer token. Establish the plugin's own session from `user_id` /
|
||||
`user_role` and authenticate API calls back to litellm through the
|
||||
`/plugin-proxy/my-plugin/*` reverse proxy, which injects `plugin_key` for you.
|
||||

## How iframe auth works
|
||||
|
||||
```
|
||||
litellm UI
|
||||
├─ GET /api/plugins/auth-token -> { session_claim }
|
||||
└─ postMessage({ type:"litellm-auth", session_claim }, pluginOrigin)
|
||||
│
|
||||
▼
|
||||
Plugin iframe browser
|
||||
└─ POST /api/plugin-auth { session_claim }
|
||||
│
|
||||
▼
|
||||
Plugin server
|
||||
├─ decrypt(session_claim, PLUGIN_AUTH_KEY) -> { user_id, user_role, exp }
|
||||
└─ establish plugin session -> stored in sessionStorage
|
||||
```
|
||||
|
||||
No litellm bearer token ever leaves the proxy; the claim only conveys the
|
||||
caller's identity and expires after 30 seconds. A postMessage intercept
|
||||
yields ciphertext that is useless without the plugin's scoped key.
|
||||
|
||||

|
||||
|
||||
## Proxy routes
|
||||
|
||||
- `GET /api/plugins` — list registered plugins (`name`, `display_name`, `url`). `plugin_key` is **never** returned; it stays server-side. Requires an authenticated caller.
|
||||
- `GET /api/plugins/auth-token?plugin_name=<name>` — short-lived encrypted identity claim for the named plugin. Requires `LITELLM_SALT_KEY` to be set (503 otherwise) and the plugin to be registered (404 otherwise).
|
||||
- `ANY /plugin-proxy/{name}/{path}` — authenticated reverse proxy to the plugin backend. Restricted to `proxy_admin`.
|
||||
|
||||
---
|
||||
|
||||
## Reverse proxy behaviour
|
||||
|
||||
When an admin (or server-to-server caller) hits `/plugin-proxy/<name>/<path>`, the proxy authenticates the caller locally, then rewrites the request before forwarding it to the plugin's `url`:
|
||||
|
||||
- **Every litellm credential header is stripped** — `Authorization`, `x-api-key`, `API-Key`, `x-goog-api-key`, `Ocp-Apim-Subscription-Key`, `x-litellm-api-key`, any configured `litellm_key_header_name`, plus `Cookie`. The plugin can never be handed the caller's live litellm key.
|
||||
- **`plugin_key` is injected** as `Authorization: Bearer <plugin_key>` — the only credential the plugin receives.
|
||||
- **Caller identity is forwarded** as `x-litellm-user-id` and `x-litellm-user-role` so the plugin can run its own authorization. These are informational, not credentials.
|
||||
- **Responses are sandboxed** — `Content-Security-Policy: sandbox` and `X-Content-Type-Options: nosniff` are set so plugin-controlled bytes served from the litellm origin cannot execute against the dashboard.
|
||||

|
||||
|
||||
## Security checklist
|
||||
|
||||
- [ ] `LITELLM_SALT_KEY` is set on the proxy and never shared with the plugin
|
||||
- [ ] The plugin holds only its derived `HMAC(LITELLM_SALT_KEY, plugin_name)` key, provisioned as a dedicated secret
|
||||
- [ ] `plugin_key` is a dedicated credential scoped to the plugin (not your litellm master key)
|
||||
- [ ] Plugin's `POST /api/plugin-auth` enforces the claim's `plugin` audience and `exp` (30s TTL)
|
||||
- [ ] Plugin treats `x-litellm-user-id` / `x-litellm-user-role` as identity hints, not as proof of authentication
|
||||
- [ ] Plugin service URL uses HTTPS in production
