+
+### MontyPythonTool
+
+Bases: <code>Tool</code>
+
+A Haystack `Tool` that lets an `Agent` run Python code in a [Monty](https://pydantic.dev/docs/monty/) sandbox.
+
+Monty is a minimal Python interpreter written in Rust. The tool keeps a pool of Monty worker processes and runs
+every call in a fresh interpreter, so nothing leaks between calls, users, or concurrent tool invocations. The
+tool returns what the code printed, the `repr()` of its last expression, and any error as a traceback, so the
+LLM can read the result and fix its code.
+
+### Security model
+
+Monty is a language-level sandbox: its interpreter implements no operation that reaches the host, so code has
+no access to files, the network, environment variables, or subprocesses. It runs in worker subprocesses started
+with an empty environment, so a crash never takes down the host process. The tool mounts no directories and
+exposes no host functions to the sandbox. Execution time and heap memory are capped by `resource_limits`.
+
+### Usage example
+
+```python
+from haystack.components.agents import Agent
+from haystack.components.generators.chat import OpenAIChatGenerator
+from haystack.dataclasses import ChatMessage
+from haystack_integrations.tools.monty import MontyPythonTool
+
+# Requires the OPENAI_API_KEY environment variable
+agent = Agent(chat_generator=OpenAIChatGenerator(), tools=[MontyPythonTool()])
+result = agent.run(messages=[ChatMessage.from_user("What is the sum of the first 100 prime numbers?")])
+print(result["last_message"].text)
+# >> The sum of the first 100 prime numbers is 24133.
+```
+
+#### __init__
+
+```python
+__init__(
+    *,
+    name: str = "run_python",
+    description: str | None = None,
+    resource_limits: ResourceLimits | None = None,
+    type_check: bool = False,
+    max_output_chars: int = 20000
+) -> None
+```
+
+Create a MontyPythonTool.
+
+**Parameters:**
+
+- **name** (<code>str</code>) – Tool name exposed to the LLM.
+- **description** (<code>str | None</code>) – Tool description exposed to the LLM. If `None`, a description of the sandbox and the
+  supported Python subset is used.
+- **resource_limits** (<code>ResourceLimits | None</code>) – Monty resource limits for each call, merged over the defaults of 30 seconds of
+  execution time (`max_feed_duration_secs`) and 256 MiB of heap memory (`max_memory`). Set a key to `None`
+  to disable that limit. See `pydantic_monty.ResourceLimits` for the available keys.
+- **type_check** (<code>bool</code>) – If `True`, type-check the code with Monty's bundled type checker before running it, and
+  return type errors to the LLM instead of executing the code.
+- **max_output_chars** (<code>int</code>) – Maximum number of characters kept from each of the printed output, the result, and
+  the error before they are returned to the LLM. The output and the result keep their beginning, the error
+  keeps its end, where the exception is.
+
+**Raises:**
+
+- <code>ValueError</code> – If `resource_limits` contains a key that Monty doesn't support, or `max_output_chars` is
+  less than 1.
+
+#### warm_up
+
+```python
+warm_up() -> None
+```
+
+Start the pool of Monty worker processes. Called by `Agent.warm_up()`; safe to call more than once.
+
+#### close
+
+```python
+close() -> None
+```
+
+Shut down the pool of Monty worker processes.
+
+Safe to call more than once. The tool starts a new pool if it is invoked again.
+
+#### to_dict
+
+```python
+to_dict() -> dict[str, Any]
+```
+
+Serialize the tool to a dictionary.
+
+**Returns:**
+
+- <code>dict\[str, Any\]</code> – Dictionary with serialized data.
+
+#### from_dict
+
+```python
+from_dict(data: dict[str, Any]) -> MontyPythonTool
+```
+
+Deserialize the tool from a dictionary.
+
+**Parameters:**
+
+- **data** (<code>dict\[str, Any\]</code>) – Dictionary to deserialize from.
+
+**Returns:**
+
+- <code>MontyPythonTool</code> – Deserialized tool.

+## haystack_integrations.tools.monty.python_tool
+
+### MontyPythonTool
+
+Bases: <code>Tool</code>
+
+A Haystack `Tool` that lets an `Agent` run Python code in a [Monty](https://pydantic.dev/docs/monty/) sandbox.
+
+Monty is a minimal Python interpreter written in Rust. The tool keeps a pool of Monty worker processes and runs
+every call in a fresh interpreter, so nothing leaks between calls, users, or concurrent tool invocations. The
+tool returns what the code printed, the `repr()` of its last expression, and any error as a traceback, so the
+LLM can read the result and fix its code.
+
+### Security model
+
+Monty is a language-level sandbox: its interpreter implements no operation that reaches the host, so code has
+no access to files, the network, environment variables, or subprocesses. It runs in worker subprocesses started
+with an empty environment, so a crash never takes down the host process. The tool mounts no directories and
+exposes no host functions to the sandbox. Execution time and heap memory are capped by `resource_limits`.
+
+### Usage example
+
+```python
+from haystack.components.agents import Agent
+from haystack.components.generators.chat import OpenAIChatGenerator
+from haystack.dataclasses import ChatMessage
+from haystack_integrations.tools.monty import MontyPythonTool
+
+# Requires the OPENAI_API_KEY environment variable
+agent = Agent(chat_generator=OpenAIChatGenerator(), tools=[MontyPythonTool()])
+result = agent.run(messages=[ChatMessage.from_user("What is the sum of the first 100 prime numbers?")])
+print(result["last_message"].text)
+# >> The sum of the first 100 prime numbers is 24133.
+```
+
+#### __init__
+
+```python
+__init__(
+    *,
+    name: str = "run_python",
+    description: str | None = None,
+    resource_limits: ResourceLimits | None = None,
+    type_check: bool = False,
+    max_output_chars: int = 20000
+) -> None

+## haystack_integrations.tools.monty.python_tool
+
+### MontyPythonTool
+
+Bases: <code>Tool</code>
+
+A Haystack `Tool` that lets an `Agent` run Python code in a [Monty](https://pydantic.dev/docs/monty/) sandbox.
+
+Monty is a minimal Python interpreter written in Rust. The tool keeps a pool of Monty worker processes and runs
+every call in a fresh interpreter, so nothing leaks between calls, users, or concurrent tool invocations. The
+tool returns what the code printed, the `repr()` of its last expression, and any error as a traceback, so the
+LLM can read the result and fix its code.
+
+### Security model
+
+Monty is a language-level sandbox: its interpreter implements no operation that reaches the host, so code has
+no access to files, the network, environment variables, or subprocesses. It runs in worker subprocesses started
+with an empty environment, so a crash never takes down the host process. The tool mounts no directories and
+exposes no host functions to the sandbox. Execution time and heap memory are capped by `resource_limits`.
+
+### Usage example
+
+```python
+from haystack.components.agents import Agent
+from haystack.components.generators.chat import OpenAIChatGenerator
+from haystack.dataclasses import ChatMessage
+from haystack_integrations.tools.monty import MontyPythonTool
+
+# Requires the OPENAI_API_KEY environment variable
+agent = Agent(chat_generator=OpenAIChatGenerator(), tools=[MontyPythonTool()])
+result = agent.run(messages=[ChatMessage.from_user("What is the sum of the first 100 prime numbers?")])
+print(result["last_message"].text)
+# >> The sum of the first 100 prime numbers is 24133.
+```
+
+#### __init__
+
+```python
+__init__(
+    *,
+    name: str = "run_python",
+    description: str | None = None,
+    resource_limits: ResourceLimits | None = None,
+    type_check: bool = False,
+    max_output_chars: int = 20000
+) -> None
+```
+
+Create a MontyPythonTool.
+
+**Parameters:**
+
+- **name** (<code>str</code>) – Tool name exposed to the LLM.
+- **description** (<code>str | None</code>) – Tool description exposed to the LLM. If `None`, a description of the sandbox and the
+  supported Python subset is used.
+- **resource_limits** (<code>ResourceLimits | None</code>) – Monty resource limits for each call, merged over the defaults of 30 seconds of
+  execution time (`max_feed_duration_secs`) and 256 MiB of heap memory (`max_memory`). Set a key to `None`
+  to disable that limit. See `pydantic_monty.ResourceLimits` for the available keys.
+- **type_check** (<code>bool</code>) – If `True`, type-check the code with Monty's bundled type checker before running it, and
+  return type errors to the LLM instead of executing the code.
+- **max_output_chars** (<code>int</code>) – Maximum number of characters kept from each of the printed output, the result, and
+  the error before they are returned to the LLM. The output and the result keep their beginning, the error
+  keeps its end, where the exception is.
+
+**Raises:**
+
+- <code>ValueError</code> – If `resource_limits` contains a key that Monty doesn't support, or `max_output_chars` is
+  less than 1.
+
+#### warm_up
+
+```python
+warm_up() -> None
+```
+
+Start the pool of Monty worker processes. Called by `Agent.warm_up()`; safe to call more than once.
+
+#### close
+
+```python
+close() -> None
+```
+
+Shut down the pool of Monty worker processes.
+
+Safe to call more than once. The tool starts a new pool if it is invoked again.
+
+#### to_dict
+
+```python
+to_dict() -> dict[str, Any]
+```
+
+Serialize the tool to a dictionary.
+
+**Returns:**
+
+- <code>dict\[str, Any\]</code> – Dictionary with serialized data.
+
+#### from_dict
+
+```python
+from_dict(data: dict[str, Any]) -> MontyPythonTool
+```
+
+Deserialize the tool from a dictionary.
+
+**Parameters:**
+
+- **data** (<code>dict\[str, Any\]</code>) – Dictionary to deserialize from.
+
+**Returns:**
+
+- <code>MontyPythonTool</code> – Deserialized tool.

+  supported Python subset is used.
+- **resource_limits** (<code>ResourceLimits | None</code>) – Monty resource limits for each call, merged over the defaults of 30 seconds of
+  execution time (`max_feed_duration_secs`) and 256 MiB of heap memory (`max_memory`). Set a key to `None`
+  to disable that limit. See `pydantic_monty.ResourceLimits` for the available keys.
+- **type_check** (<code>bool</code>) – If `True`, type-check the code with Monty's bundled type checker before running it, and
+  return type errors to the LLM instead of executing the code.
+- **max_output_chars** (<code>int</code>) – Maximum number of characters kept from each of the printed output, the result, and
+  the error before they are returned to the LLM. The output and the result keep their beginning, the error
+  keeps its end, where the exception is.
+
+**Raises:**
+
+- <code>ValueError</code> – If `resource_limits` contains a key that Monty doesn't support, or `max_output_chars` is

+
+#### warm_up
+
+```python
+warm_up() -> None
+```
+
+Start the pool of Monty worker processes. Called by `Agent.warm_up()`; safe to call more than once.

+## haystack_integrations.tools.monty.python_tool
+
+### MontyPythonTool
+
+Bases: <code>Tool</code>
+
+A Haystack `Tool` that lets an `Agent` run Python code in a [Monty](https://pydantic.dev/docs/monty/) sandbox.
+
+Monty is a minimal Python interpreter written in Rust. The tool keeps a pool of Monty worker processes and runs
+every call in a fresh interpreter, so nothing leaks between calls, users, or concurrent tool invocations. The
+tool returns what the code printed, the `repr()` of its last expression, and any error as a traceback, so the
+LLM can read the result and fix its code.
+
+### Security model
+
+Monty is a language-level sandbox: its interpreter implements no operation that reaches the host, so code has
+no access to files, the network, environment variables, or subprocesses. It runs in worker subprocesses started
+with an empty environment, so a crash never takes down the host process. The tool mounts no directories and
+exposes no host functions to the sandbox. Execution time and heap memory are capped by `resource_limits`.
+
+### Usage example
+
+```python
+from haystack.components.agents import Agent
+from haystack.components.generators.chat import OpenAIChatGenerator
+from haystack.dataclasses import ChatMessage
+from haystack_integrations.tools.monty import MontyPythonTool
+
+# Requires the OPENAI_API_KEY environment variable
+agent = Agent(chat_generator=OpenAIChatGenerator(), tools=[MontyPythonTool()])
+result = agent.run(messages=[ChatMessage.from_user("What is the sum of the first 100 prime numbers?")])
+print(result["last_message"].text)
+# >> The sum of the first 100 prime numbers is 24133.
+```
+
+#### __init__
+
+```python
+__init__(
+    *,
+    name: str = "run_python",
+    description: str | None = None,
+    resource_limits: ResourceLimits | None = None,
+    type_check: bool = False,
+    max_output_chars: int = 20000
+) -> None
+```

+
+**Parameters:**
+

+```
+
+Shut down the pool of Monty worker processes.
+
+Safe to call more than once. The tool starts a new pool if it is invoked again.
+
+#### to_dict
+
+```python
