## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `NANGO_ACTION_TRIGGER_POST` | Trigger Nango Action | Trigger a Nango action to execute a workflow or operation. Use this to run pre-defined actions in your Nango integrations, such as creating issues, sending messages, or fetching data from external APIs. All three of `connection_id`, `provider_config_key`, and `action_name` must simultaneously match a pre-configured integration and connection in Nango — a valid `connection_id` alone is insufficient if the other two don't correspond to an existing setup. Actions may have real upstream side effects (e.g., creating records, sending messages); confirm intent before triggering non-read-only operations. |
| `NANGO_ADD_CONNECTION` | Add Connection | Tool to add a connection with existing credentials to Nango. Use when you want to bulk import existing access tokens into Nango. |
| `NANGO_CONNECTION_LIST_GET` | List Connections | List all Nango connections without credentials. Use this to discover available connections, check connection status, and find connection IDs. Omitting all filters returns every connection across all integrations; use `connection_id`, `end_user_id`, or `end_user_organization_id` to narrow results. To retrieve credentials for a specific connection, use the 'Get Connection Details' action. |
| `NANGO_CREATE_CONNECT_SESSION` | Create Connect Session | Tool to create a new connect session with a 30-minute lifespan for enabling connection creation via Connect UI. Use when you need to generate a session token for users to authorize integrations through Nango's Connect interface. |
| `NANGO_CREATE_INTEGRATION` | Create Integration | Tool to create a new integration in Nango. Use when setting up a new provider connection configuration. Creates an integration with specified credentials (OAuth2, App-based, or Hybrid authentication). The unique_key will be used to reference this integration in subsequent API calls. Returns the created integration details including timestamps and provider information. |
| `NANGO_DELETE_CONNECTION` | Delete Connection | Tool to delete a specific Nango connection. Use when you need to remove an existing connection permanently. |
| `NANGO_DELETE_INTEGRATION` | Delete Integration | Tool to delete a specific integration by its unique key. Use when you need to remove an integration configuration from Nango. |
| `NANGO_EDIT_CONNECTION` | Edit Connection | Tool to edit a connection's tags and metadata. Use when you need to update connection attributes like environment tags, team assignments, or end user information. |
| `NANGO_GET_CONNECTION` | Get Connection with Credentials | Retrieve a specific connection with its credentials. Automatically checks if the access token has expired and refreshes it if needed. Use this action when you need to access the authentication credentials for a connection to make API calls to the provider. The credentials returned depend on the auth type (OAuth2, API Key, Basic Auth, etc.). Returns 404 if the connection does not exist, 424 if token refresh is exhausted. |
| `NANGO_GET_ENVIRONMENT_VARIABLES` | Get Environment Variables | Tool to retrieve environment variables from the Nango dashboard. Use when you need to access or list environment variables configured in Nango. |
| `NANGO_GET_INTEGRATION` | Get Integration | Retrieve detailed configuration for a specific Nango integration by its unique key. Returns integration details including provider, display name, creation/update timestamps, and optionally sensitive data like credentials or webhook URLs if requested via the 'include' parameter. Use this to inspect integration configuration, verify setup, or retrieve credentials for a specific integration. Returns 404 error if the integration unique key does not exist. |
| `NANGO_GET_PROXY` | Proxy GET Request | Tool to make a GET request with Nango's Proxy to forward requests to external APIs while managing authentication. Use when you need to make authenticated API calls to external services through Nango's proxy infrastructure. |
| `NANGO_GET_SYNC_STATUS` | Get Sync Status | Tool to get the status of specified sync(s) for a connection or all connections. Use when you need to monitor sync execution state, check completion times, or view sync frequency. |
| `NANGO_CONNECTION_LIST_GET` | List Connections | Tool to list all connections without credentials. Use when you need to retrieve connection metadata across your account. |
| `NANGO_LIST_INTEGRATIONS` | List Integrations | Tool to retrieve a list of all configured integrations. Use when you need to display or iterate through integrations in your account. |
| `NANGO_PROVIDERS_GET_GET` | Get Provider Details | Retrieve detailed configuration for a specific Nango provider by its unique key. Returns provider authentication details (auth_mode, OAuth URLs), proxy configuration, required credentials schema, and connection configuration requirements. Use this to understand how to set up a connection with a specific provider or to get its documentation links. Provider keys can be obtained from the List Providers action. Returns 404 error if provider key does not exist. |
| `NANGO_PROVIDERS_LIST_GET` | List Providers | Tool to retrieve a list of all available providers. Use when you need to display or iterate through every provider before creating connections. The provider_config_key values returned must be used verbatim when referencing providers in other actions; any mismatch will cause those actions to fail. |
| `NANGO_PUT_PROXY` | Proxy PUT Request | Tool to make a PUT request with the Nango Proxy to forward requests to external APIs while managing authentication. Use when you need to update resources via external APIs through Nango's proxy. |
| `NANGO_RECONNECT_SESSION_POST` | Reconnect Session | Create a new connect session to reconnect to a specific integration. Use this when a user needs to input new credentials or to manually refresh a token. Only connections created with a connect session are compatible with this endpoint. |
| `NANGO_SCRIPTS_CONFIG_GET` | Get Integration Functions Configuration | Retrieve all integration functions configuration from Nango. Returns the configuration for all integrations including their sync scripts, action scripts, and event handlers. Use this to discover available integrations and their capabilities before triggering syncs or actions. |
| `NANGO_SET_CONNECTION_METADATA` | Set Connection Metadata | Tool to set custom metadata for one or more Nango connections. Use when you need to attach custom data (tags, labels, context) to connections for filtering, organization, or application-specific purposes. |
| `NANGO_SYNC_TRIGGER_POST` | Trigger Sync | Tool to trigger sync process(es) manually. Use after establishing a connection and defining syncs. This triggers an additional, one-off execution of the specified sync(s) for a given connection or all applicable connections. Useful when you changed metadata for a connection and want to re-import data. |
| `NANGO_UPDATE_CONNECTION_METADATA` | Update Connection Metadata | Tool to edit custom metadata for one or multiple connections. Use when you need to update specific metadata properties without overwriting the entire metadata object. |
| `NANGO_UPDATE_INTEGRATION` | Update Integration | Tool to update an existing integration's configuration. Use when you need to modify an integration's display name, unique key, or credentials. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
```python
pip install composio composio_openai openai
```

```typescript
npm install @composio/core @composio/openai openai
```

#### Path 1, Step 2: Create a Composio session

Initialize Composio with the OpenAI Responses provider and create a session scoped to Nango
```python
import json
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
client = OpenAI()

session = composio.create(user_id="your-user-id", toolkits=["nango"])
tools = session.tools()
```

```typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["nango"] });
const tools = await session.tools();
```

#### Path 1, Step 3: Run Nango tools with your agent

Send a request, execute the Nango tool calls through the session, and print the final answer
```python
response = client.responses.create(
    model="gpt-5.6-sol",
    tools=tools,
    input=[{"role": "user", "content": "List all active Salesforce connections in my account"}],
)

while True:
    tool_calls = [o for o in response.output if o.type == "function_call"]
    if not tool_calls:
        break
    results = composio.provider.handle_tool_calls(response=response, session=session)
    response = client.responses.create(
        model="gpt-5.6-sol",
        tools=tools,
        previous_response_id=response.id,
        input=[
            {"type": "function_call_output", "call_id": call.call_id, "output": json.dumps(results[i])}
            for i, call in enumerate(tool_calls)
        ],
    )

print(response.output_text)
```

```typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "List all active Salesforce connections in my account" }],
});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK and your agent framework
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
```

#### Path 2, Step 2: Create a session with MCP enabled

Create a session scoped to Nango and read its MCP URL and headers
```python
from composio import Composio

composio = Composio()
session = composio.create(user_id="your-user-id", toolkits=["nango"], mcp=True)
```

```typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["nango"],
  mcp: true,
});
```

#### Path 2, Step 3: Connect your agent to the MCP server

Pass the session's MCP URL and headers to your agent and run a Nango request
```python
import asyncio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions, AssistantMessage, TextBlock

options = ClaudeAgentOptions(
    mcp_servers={
        "composio": {
            "type": "http",
            "url": session.mcp.url,
            "headers": session.mcp.headers,
        }
    },
    system_prompt="You are a helpful assistant with access to Nango tools.",
    tools=[],
    allowed_tools=["mcp__composio__*"],
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query("List all active Salesforce connections in my account")
        async for message in client.receive_response():
            if isinstance(message, AssistantMessage):
                for block in message.content:
                    if isinstance(block, TextBlock):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "List all active Salesforce connections in my account",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
```
