+## Forwarding Custom Headers to MCP Servers
+
+LiteLLM supports forwarding additional custom headers from MCP clients to backend MCP servers using the `extra_headers` configuration parameter. This allows you to pass custom authentication tokens, API keys, or other headers that your MCP server requires.
+
+### Configuration
+
+
+<Tabs>
+<TabItem value="config" label="config.yaml">
+Configure `extra_headers` in your MCP server configuration to specify which header names should be forwarded:

+
+**Format:** `x-mcp-{server_alias}-{header_name}: value`
+
+This allows you to use different authentication for different MCP servers.
+
+
+**Examples:**
+- `x-mcp-github-authorization: Bearer ghp_xxxxxxxxx` - GitHub MCP server with Bearer token
+- `x-mcp-zapier-x-api-key: sk-xxxxxxxxx` - Zapier MCP server with API key

+
+### How It Works
+
+1. **Configuration**: Define `extra_headers` in your MCP server config with the header names you want to forward
+2. **Client Headers**: Include the corresponding headers in your MCP client requests
+3. **Header Forwarding**: LiteLLM automatically forwards matching headers to the backend MCP server
+4. **Authentication**: The backend MCP server receives both the configured auth headers and the custom headers
+
+### Use Cases
+
+- **Custom Authentication**: Forward custom API keys or tokens required by specific MCP servers
+- **Request Context**: Pass user identification, session data, or request tracking headers
+- **Third-party Integration**: Include headers required by external services that your MCP server integrates with
+- **Multi-tenant Systems**: Forward tenant-specific headers for proper request routing
+
+### Security Considerations
+
+- Only headers listed in `extra_headers` are forwarded to maintain security
+- Sensitive headers should be passed through environment variables when possible
+- Consider using server-specific auth headers for better security isolation
+
+---
+
+## MCP Oauth
+
+LiteLLM v 1.77.6 added support for OAuth 2.0 Client Credentials for MCP servers.
+
+
+This configuration is currently available on the config.yaml, with UI support coming soon.

+```yaml

+                    "description": "The city and state"
+                }
+            },
+            "required": ["location"]
+        }
+    }
+]
+
+response = completion(
+    model="lemonade/your-model-name",
+    messages=[{"role": "user", "content": "What's the weather in San Francisco?"}],
+    tools=[{"type": "function", "function": f} for f in functions],
+    tool_choice="auto"
+)
+print(response)
+```
+
+### Response Format
+
+Lemonade supports structured output with response format:
+
+```python
+from litellm import completion
+import json
+
+# Define schema in response_format
+response = completion(
+    model="lemonade/Qwen3-Coder-30B-A3B-Instruct-GGUF",
+    messages=[{"role": "user", "content": "Generate JSON data for a person with their name, age, and city."}],
+    response_format={
+        "type": "json_schema",
+        "json_schema": {
+            "name": "person",
+            "schema": {
+                "type": "object",
+                "properties": {
+                    "name": {"type": "string"},
+                    "age": {"type": "integer"},
+                    "city": {"type": "string"}
+                },
+                "required": ["name", "age"]
+            }
+        }
+    }
+)
+
+print(f"Model: {response.model}")
+print(f"JSON Output:")
+json_data = json.loads(response.choices[0].message.content)
+print(json.dumps(json_data, indent=2))
+```
+
+## Available Models
+
+Lemonade automatically validates available models by querying the `/models` endpoint. You can check available models programmatically:
+
+```python
+import httpx
+
+api_base = "http://localhost:8000"  # or your custom base
+response = httpx.get(f"{api_base}/api/v1/models")
+models = response.json()
+print("Available models:", [model['id'] for model in models.get('data', [])])
+```
+

+# Javelin Guardrails
+
+Javelin provides AI safety and content moderation services with support for prompt injection detection, trust & safety violations, and language detection.
+
+## Quick Start
+### 1. Define Guardrails on your LiteLLM config.yaml 
+
+Define your guardrails under the `guardrails` section
+
+```yaml showLineNumbers title="litellm config.yaml"

+      api_base: os.environ/JAVELIN_API_BASE
+      guardrail_name: "lang_detector"
+      api_version: "v1"
+```
+
+#### Supported values for `mode`
+
+- `pre_call` Run **before** LLM call, on **input**
+- `post_call` Run **after** LLM call, on **input & output**
+- `during_call` Run **during** LLM call, on **input** Same as `pre_call` but runs in parallel as LLM call. Response not returned until guardrail check completes
+
+### 2. Start LiteLLM Gateway 
+
+```shell
+litellm --config config.yaml --detailed_debug
+```
+
+### 3. Test request

+
+## Supported Guardrail Types
+
+### 1. Prompt Injection Detection (`promptinjectiondetection`)
+
+Detects and blocks prompt injection and jailbreak attempts.
+
+**Categories:**
+- `prompt_injection`: Detects attempts to manipulate the AI system
+- `jailbreak`: Detects attempts to bypass safety measures
+
+**Example Response:**
+```json
+{
+  "assessments": [
+    {
+      "promptinjectiondetection": {
+        "request_reject": true,
+        "results": {
+          "categories": {
+            "jailbreak": false,
+            "prompt_injection": true
+          },
+          "category_scores": {
+            "jailbreak": 0.04,
+            "prompt_injection": 0.97
+          },
+          "reject_prompt": "Unable to complete request, prompt injection/jailbreak detected"
+        }
+      }
+    }
+  ]
+}
+```
+
+### 2. Trust & Safety (`trustsafety`)
+
+Detects harmful content across multiple categories.
+
+**Categories:**
+- `violence`: Violence-related content
+- `weapons`: Weapon-related content
+- `hate_speech`: Hate speech and discriminatory content
+- `crime`: Criminal activity content
+- `sexual`: Sexual content
+- `profanity`: Profane language
+
+**Example Response:**
+```json
+{
+  "assessments": [
+    {
+      "trustsafety": {
+        "request_reject": true,
+        "results": {
+          "categories": {
+            "violence": true,
+            "weapons": true,
+            "hate_speech": false,
+            "crime": false,
+            "sexual": false,
+            "profanity": false
+          },
+          "category_scores": {
+            "violence": 0.95,
+            "weapons": 0.88,
+            "hate_speech": 0.02,
+            "crime": 0.03,
+            "sexual": 0.01,
+            "profanity": 0.01
+          },
+          "reject_prompt": "Unable to complete request, trust & safety violation detected"
+        }
+      }
+    }
+  ]
+}
+```
+
+### 3. Language Detection (`lang_detector`)
+
+Detects the language of input text and can enforce language policies.
+
+**Example Response:**
+```json
+{
+  "assessments": [
+    {
+      "lang_detector": {
+        "request_reject": true,
+        "results": {
+          "lang": "hi",
+          "prob": 0.95,
+          "reject_prompt": "Unable to complete request, language violation detected"
+        }
+      }
+    }
+  ]
+}
+```
+
+## Supported Params 
+
+```yaml
+guardrails:
+  - guardrail_name: "javelin-guard"
+    litellm_params:
+      guardrail: javelin
+      mode: "pre_call"
+      api_key: os.environ/JAVELIN_API_KEY
+      api_base: os.environ/JAVELIN_API_BASE
+      guardrail_name: "promptinjectiondetection"  # or "trustsafety", "lang_detector"
+      api_version: "v1"
+      ### OPTIONAL ### 
+      # metadata: Optional[Dict] = None,
+      # config: Optional[Dict] = None,
+      # application: Optional[str] = None,
+      # default_on: bool = True
+```
+
+- `api_base`: (Optional[str]) The base URL of the Javelin API. Defaults to `https://api-dev.javelin.live`
+- `api_key`: (str) The API Key for the Javelin integration.
+- `guardrail_name`: (str) The type of guardrail to use. Supported values: `promptinjectiondetection`, `trustsafety`, `lang_detector`
+- `api_version`: (Optional[str]) The API version to use. Defaults to `v1`
+- `metadata`: (Optional[Dict]) Metadata tags can be attached to screening requests as an object that can contain any arbitrary key-value pairs.
+- `config`: (Optional[Dict]) Configuration parameters for the guardrail.
+- `application`: (Optional[str]) Application name for policy-specific guardrails.
+- `default_on`: (Optional[bool]) Whether the guardrail is enabled by default. Defaults to `True`
+
+## Environment Variables
+
+Set the following environment variables:
+
+```bash
+export JAVELIN_API_KEY="your-javelin-api-key"
+export JAVELIN_API_BASE="https://api-dev.javelin.live"  # Optional, defaults to dev environment
+```
+
+## Error Handling
+
+When a guardrail detects a violation:
+
+1. The **last message content** is replaced with the appropriate reject prompt
+2. The message role remains unchanged
+3. The request continues with the modified message
+4. The original violation is logged for monitoring
+
+**How it works:**
+- Javelin guardrails check the last message for violations
+- If a violation is detected (`request_reject: true`), the content of the last message is replaced with the reject prompt
+- The message structure remains intact, only the content changes
+
+**Reject Prompts:**
+Can be configured from javelin portal.
+- Prompt Injection: `"Unable to complete request, prompt injection/jailbreak detected"`
+- Trust & Safety: `"Unable to complete request, trust & safety violation detected"`
+- Language Detection: `"Unable to complete request, language violation detected"`
+
+## Testing
+
+You can test the Javelin guardrails using the provided test suite:
+
+```bash
+pytest tests/guardrails_tests/test_javelin_guardrails.py -v
+```
+
+The tests include mocked responses to avoid external API calls during testing.

+## 🔁 Scheduled Key Rotations (NEW in v1.77.5)
+
+LiteLLM can now rotate **virtual keys automatically** on a schedule you define.
+
+### How it works
+1. When creating a virtual key you set `rotation_schedule` – a [cron expression](https://crontab.guru/).
+2. LiteLLM stores the schedule in the DB and runs a background job that regenerates the key at the specified time.
+3. Existing key string is invalidated; a **notification webhook** (if configured) is sent with the new key value.
+
+### Create a key with rotation
+
+```bash
+curl 'http://0.0.0.0:4000/key/generate' \
+  -H 'Authorization: Bearer <your-master-key>' \
+  -H 'Content-Type: application/json' \
+  -d '{
+        "models": ["gpt-4o"],
+        "rotation_schedule": "0 0 * * SUN",   # rotate every Sunday at 00:00 UTC
+        "webhook_url": "https://example.com/key-rotated"
+      }'
+```
+
+### Enable globally via env
+
+Set these env vars when starting the proxy:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `LITELLM_KEY_ROTATION_ENABLED` | Enable the rotation worker | `false` |
+| `LITELLM_KEY_ROTATION_CHECK_INTERVAL_SECONDS` | How often to scan for keys to rotate | `86400` |
+
+### Webhook payload
+
+```json
+{
+  "event": "virtual_key.rotated",
+  "old_key_id": "sk-abc...",
+  "new_key": "sk-def...",
+  "rotation_time": "2025-10-05T00:00:00Z"
+}
+```
+
+If no `webhook_url` is provided the new key value is returned in the response of the `/key/rotate` REST call instead.
