+# HuggingFace Prompt Renderer MCP Server
+
+Model Context Protocol (MCP) server for rendering conversation messages into
+model-specific prompt strings using HuggingFace tokenizer chat templates.
+
+## Requirements
+
+- [uv](https://docs.astral.sh/uv/) - Fast Python package installer
+
+## Usage
+
+### MCP Server Mode
+
+Run the MCP server over stdio for use with MCP clients:
+
+```bash
+uv run cmd/prompt-rendering/server.py --mcp
+```
+
+Add to your MCP client configuration (e.g., for Claude Desktop):
+
+```json
+{
+  "mcpServers": {
+    "huggingface-prompt-renderer": {
+      "command": "uv",
+      "args": [
+        "run",
+        "--directory",
+        "<path-to-ollama-repo>",
+        "cmd/prompt-rendering/server.py",
+        "--mcp"
+      ]
+    }
+  }
+}
+```
+
+### FastAPI Server Mode
+
+Start a FastAPI server for manual HTTP testing:
+
+```bash
+# Start on default port 8000
+uv run cmd/prompt-rendering/server.py --host 0.0.0.0 --port 8000
+
+# Start on custom port
+uv run cmd/prompt-rendering/server.py --host 0.0.0.0 --port 9000
+```
+
+#### Endpoints
+
+| Method | Path | Description |
+|--------|------|-------------|
+| POST | `/generate-prompt` | Generate prompt from messages |
+| GET | `/health` | Health check |
+
+### Test with curl
+
+```bash
+# Basic user message
+curl -X POST http://localhost:8000/generate-prompt \
+  -H "Content-Type: application/json" \
+  -d '{
+    "messages": [{"role": "user", "content": "Hello!"}]
+  }'
+
+# With tools
+curl -X POST http://localhost:8000/generate-prompt \
+  -H "Content-Type: application/json" \
+  -d '{
+    "messages": [
+      {"role": "system", "content": "You are a helpful assistant."},
+      {"role": "user", "content": "What is the weather?"}
+    ],
+    "model": "Qwen/Qwen3-Coder-480B-A35B-Instruct",
+    "tools": [{
+      "type": "function",

+          }
+        }
+      }
+    }]
+  }'
+
+# With tool calls
+curl -X POST http://localhost:8000/generate-prompt \
+  -H "Content-Type: application/json" \
+  -d '{
+    "messages": [
+      {"role": "user", "content": "What is the weather in SF?"},
+      {
+        "role": "assistant",
+        "tool_calls": [{
+          "id": "call_1",
+          "type": "function",
+          "function": {
+            "name": "get_weather",
+            "arguments": {"location": "San Francisco"}
+          }
+        }]
+      },
+      {"role": "tool", "content": "{\"temperature\": 68}", "tool_call_id": "call_1"}
+    ],
+    "tools": [{
+      "type": "function",
+      "function": {
+        "name": "get_weather",
+        "parameters": {
+          "type": "object",
+          "properties": {"location": {"type": "string"}}
+        }
+      }
+    }]
+  }'
+```
+
+## Supported Message Formats
+
+The server supports multiple message formats:
+
+| Format | Description |
+|--------|-------------|
+| OpenAI | Standard `role`, `content`, `tool_calls`, `tool_call_id` |
+| OLMo | Adds `functions` and `function_calls` fields |
+| DeepSeek | Tool call arguments must be JSON strings |
+
+## Tool Support
+
+| Setting | Description |
+|---------|-------------|
+| `inject_tools_as_functions=true` | Injects tools into system message as `functions` key (OLMo-style) |
+| `inject_tools_as_functions=false` | Passes tools separately to `apply_chat_template` (standard transformers) |
+
+## Models
+
+The server uses HuggingFace's `transformers` library and supports any model
+with a chat template. Default: `Qwen/Qwen3-Coder-480B-A35B-Instruct`
+
+## Dependencies
+
+The script uses PEP 723 inline dependency metadata. When run with `uv`,
+dependencies are automatically installed into an isolated environment:
+
+- `fastapi` - Web framework
+- `uvicorn` - ASGI server
+- `transformers` - HuggingFace tokenizer
+- `jinja2` - Template engine
+- `mcp` - Model Context Protocol

+        - Test edge cases: tool calling, tool responses, interleaved thinking and tool calls, multiple tools in single response
+        - Compare prompt output across different models to understand template differences
+        - Debug issues with message formatting that cause unexpected model behavior
+
+        Message format supports:
+        - role: "user", "assistant", "system", "tool"
+        - content: string content of the message
+        - tool_calls: list of tool call objects (OpenAI format: {type, function: {name, arguments}})
+        - tool_call_id: for tool role messages, references the call being responded to
+        - functions: optional field for OLMo-style tool definitions
+        - function_calls: optional field for OLMo-style tool call results
+
+        Parameters:
+        - messages: List of message dictionaries forming the conversation
+        - model: HuggingFace model identifier (default: Qwen/Qwen3-Coder-480B-A35B-Instruct)
+        - tools: Optional list of tool/function definitions for function calling models
+        - inject_tools_as_functions: If True, injects tools into system message as 'functions' key (OLMo-style). If False, passes tools separately to apply_chat_template.
+
+        Returns: Dictionary with 'prompt' (rendered string) and 'model' keys.
+
+        Recommended test cases:
+        1. Simple conversation: user -> assistant
+        2. Tool calling: user -> assistant with tool_call -> tool response -> assistant
+        3. Multiple tool calls in one assistant message
+        4. Multiple tool responses interleaved with assistant reasoning
+        5. Nested tool calls (assistant calls tool, uses result to call another)
+        6. System message with tool definitions
+        7. Empty or None content in messages
+        8. Very long messages to test truncation handling

-title: Anthropic compatibility
----
-
-Ollama provides compatibility with the [Anthropic Messages API](https://docs.anthropic.com/en/api/messages) to help connect existing applications to Ollama, including tools like Claude Code.
-
-## Recommended models
-
-For coding use cases, models like `glm-4.7:cloud`, `minimax-m2.1:cloud`, and `qwen3-coder` are recommended.
-
-Pull a model before use:
-```shell
-ollama pull qwen3-coder
-ollama pull glm-4.7:cloud
-```
-
-## Usage
-
-### Environment variables
-
-To use Ollama with tools that expect the Anthropic API (like Claude Code), set these environment variables:
-
-```shell
-export ANTHROPIC_BASE_URL=http://localhost:11434
-export ANTHROPIC_API_KEY=ollama  # required but ignored
-```
-
-### Simple `/v1/messages` example
-
-<CodeGroup dropdown>

-```python basic.py
-import anthropic
-
-client = anthropic.Anthropic(
-    base_url='http://localhost:11434',

-## Using with Claude Code
-
-[Claude Code](https://code.claude.com/docs/en/overview) can be configured to use Ollama as its backend:
-
-```shell
-ANTHROPIC_BASE_URL=http://localhost:11434 ANTHROPIC_API_KEY=ollama claude --model qwen3-coder
-```
-
-Or set the environment variables in your shell profile:
-
-```shell
-export ANTHROPIC_BASE_URL=http://localhost:11434
-export ANTHROPIC_API_KEY=ollama
-```
-
-Then run Claude Code with any Ollama model:
-
-```shell
-# Local models
-claude --model qwen3-coder
-claude --model gpt-oss:20b
-
-# Cloud models
-claude --model glm-4.7:cloud
-claude --model minimax-m2.1:cloud
-```

-## Models
-
-Ollama supports both local and cloud models.
-
-### Local models
-
-Pull a local model before use:
-
-```shell
-ollama pull qwen3-coder
-```
-
-Recommended local models:
-- `qwen3-coder` - Excellent for coding tasks
-- `gpt-oss:20b` - Strong general-purpose model
-
-### Cloud models
-
-Cloud models are available immediately without pulling:
-
-- `glm-4.7:cloud` - High-performance cloud model
-- `minimax-m2.1:cloud` - Fast cloud model
-
-### Default model names
-
-For tooling that relies on default Anthropic model names such as `claude-3-5-sonnet`, use `ollama cp` to copy an existing model name:
-
-```shell
-ollama cp qwen3-coder claude-3-5-sonnet
-```
-
-Afterwards, this new model name can be specified in the `model` field:
-
-```shell
-curl http://localhost:11434/v1/messages \
-    -H "Content-Type: application/json" \
-    -d '{
-        "model": "claude-3-5-sonnet",
-        "max_tokens": 1024,
-        "messages": [
-            {
-                "role": "user",
-                "content": "Hello!"
-            }
-        ]
-    }'
-```
-
-## Differences from the Anthropic API
-
-### Behavior differences
-
-- API key is accepted but not validated
-- `anthropic-version` header is accepted but not used
-- Token counts are approximations based on the underlying model's tokenizer
-
-### Not supported
-
-The following Anthropic API features are not currently supported:
-
-| Feature | Description |
-|---------|-------------|
-| `/v1/messages/count_tokens` | Token counting endpoint |
-| `tool_choice` | Forcing specific tool use or disabling tools |
-| `metadata` | Request metadata (user_id) |
-| Prompt caching | `cache_control` blocks for caching prefixes |
-| Batches API | `/v1/messages/batches` for async batch processing |
-| Citations | `citations` content blocks |
-| PDF support | `document` content blocks with PDF files |
-| Server-sent errors | `error` events during streaming (errors return HTTP status) |
-
-### Partial support
-
-| Feature | Status |
-|---------|--------|
-| Image content | Base64 images supported; URL images not supported |
-| Extended thinking | Basic support; `budget_tokens` accepted but not enforced |
