## Methods

### get_raw_composio_tool_by_slug()

Returns schema for the given tool slug.

```python
def get_raw_composio_tool_by_slug(slug: str) -> Tool
```

**Parameters**

| Name | Type |
|------|------|
| `slug` | `str` |

**Returns**

`Tool`

---

### get_raw_composio_tools()

Get a list of tool schemas based on the provided filters.

```python
def get_raw_composio_tools(tools: list[str | None] = ..., search: str | None = ..., toolkits: list[str | None] = ..., scopes: List[str | None] = ..., limit: int | None = ...) -> list[Tool]
```

**Parameters**

| Name | Type |
|------|------|
| `tools?` | `list[str \| None]` |
| `search?` | `str \| None` |
| `toolkits?` | `list[str \| None]` |
| `scopes?` | `List[str \| None]` |
| `limit?` | `int \| None` |

**Returns**

`list[Tool]`

---

### get_raw_tool_router_meta_tools()

Fetches the tools exposed by a tool router session.  This method fetches helper/meta tools and any preloaded app tools from the Composio API and transforms them to the expected format. It provides access to the underlying tool data without provider-specific wrapping.

```python
def get_raw_tool_router_meta_tools(session_id: str, modifiers: 'Modifiers' | None = ...) -> list[Tool]
```

**Parameters**

| Name | Type |
|------|------|
| `session_id` | `str` |
| `modifiers?` | `'Modifiers' \| None` |

**Returns**

`list[Tool]` — The list of meta tools

**Example**

```python
from composio import Composio

composio = Composio()
tools_model = composio.tools

# Get meta tools for a session
meta_tools = tools_model.get_raw_tool_router_meta_tools("session_123")
print(meta_tools)

# Get meta tools with schema modifiers
from composio.core.models import schema_modifier

@schema_modifier
def modify_schema(tool: str, toolkit: str, schema):
    # Customize the schema
    schema.description = f"Modified: {schema.description}"
    return schema

meta_tools = tools_model.get_raw_tool_router_meta_tools(
    "session_123",
    modifiers=[modify_schema]
)
```

---

### get()

Get a tool or list of tools based on the provided arguments.  The return type is automatically inferred based on the provider's generic parameters. For example: - OpenAIProvider -> list[ChatCompletionToolParam] - AnthropicProvider -> list[ToolParam] - CustomProvider[MyTool, list[MyTool]] -> list[MyTool]

```python
def get(user_id: str, slug: str | None = ..., tools: list[str | None] = ..., search: str | None = ..., toolkits: list[str | None] = ..., scopes: List[str | None] = ..., modifiers: Modifiers | None = ..., limit: int | None = ...) -> TToolCollection
```

**Parameters**

| Name | Type |
|------|------|
| `user_id` | `str` |
| `slug?` | `str \| None` |
| `tools?` | `list[str \| None]` |
| `search?` | `str \| None` |
| `toolkits?` | `list[str \| None]` |
| `scopes?` | `List[str \| None]` |
| `modifiers?` | `Modifiers \| None` |
| `limit?` | `int \| None` |

**Returns**

`TToolCollection` — Provider-specific tool collection (TToolCollection).

---

### execute()

Execute a tool with the provided parameters.  This method calls the Composio API to execute the tool and returns the response.

```python
def execute(slug: str, arguments: Dict, connected_account_id: str | None = ..., custom_auth_params: tool_execute_params.CustomAuthParams | None = ..., custom_connection_data: tool_execute_params.CustomConnectionData | None = ..., user_id: str | None = ..., text: str | None = ..., version: str | None = ..., dangerously_skip_version_check: bool | None = ..., modifiers: Modifiers | None = ...) -> ToolExecutionResponse
```

**Parameters**

| Name | Type |
|------|------|
| `slug` | `str` |
| `arguments` | `Dict` |
| `connected_account_id?` | `str \| None` |
| `custom_auth_params?` | `tool_execute_params.CustomAuthParams \| None` |
| `custom_connection_data?` | `tool_execute_params.CustomConnectionData \| None` |
| `user_id?` | `str \| None` |
| `text?` | `str \| None` |
| `version?` | `str \| None` |
| `dangerously_skip_version_check?` | `bool \| None` |
| `modifiers?` | `Modifiers \| None` |

**Returns**

`ToolExecutionResponse` — The response from the tool.

---

### proxy()

Proxy a tool call to the Composio API

```python
def proxy(endpoint: str, method: Literal['GET', 'POST', 'PUT', 'DELETE', 'PATCH', 'HEAD'], body: object | None = ..., connected_account_id: str | None = ..., parameters: List[tool_proxy_params.Parameter | None] = ..., custom_connection_data: tool_proxy_params.CustomConnectionData | None = ...) -> tool_proxy_response.ToolProxyResponse
```

**Parameters**

| Name | Type |
|------|------|
| `endpoint` | `str` |
| `method` | `Literal['GET', 'POST', 'PUT', 'DELETE', 'PATCH', 'HEAD']` |
| `body?` | `object \| None` |
| `connected_account_id?` | `str \| None` |
| `parameters?` | `List[tool_proxy_params.Parameter \| None]` |
| `custom_connection_data?` | `tool_proxy_params.CustomConnectionData \| None` |

**Returns**

`tool_proxy_response.ToolProxyResponse`
