## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CARDLY_CREATE_CONTACT_LIST` | Create Contact List | Tool to add a new contact list. Use after defining name and optional custom fields, before populating the list with contacts. |
| `CARDLY_CREATE_INVITATION` | Create Invitation | Tool to send an invitation to use your organisation portal. Use when you need to grant access to a new user by their email address. If the email already has access, the API will return an appropriate error. |
| `CARDLY_CREATE_WEBHOOK` | Create Webhook | Tool to create a new webhook subscription. Use when you need Cardly to notify your application via HTTP POST for specific events. |
| `CARDLY_DELETE_INVITATION` | Delete Invitation | Tool to delete an invitation by unique ID, immediately invalidating it for acceptance. Use when you need to revoke a pending invitation using its ID. |
| `CARDLY_DELETE_INVITATION_BY_EMAIL` | Delete Invitation by Email | Deletes a pending invitation by email address, immediately invalidating it and preventing acceptance. This action is idempotent - deleting a non-existent invitation returns success. Use when you need to revoke access before an invitation is accepted, such as when correcting mistakes or revoking access for security reasons. Note: In test mode, the API returns an empty data object instead of the deleted invitation details. |
| `CARDLY_DELETE_USER` | Delete User | Tool to delete a user by unique ID, immediately revoking their access to your organisation portal. Use when removing user access is required. Cannot remove users with administrator privileges - attempting to delete an admin will fail. |
| `CARDLY_DELETE_USER_BY_EMAIL` | Delete User by Email | Deletes a user by email address, immediately revoking their access to your organisation portal. This action cannot remove users with administrator privileges. Use when you need to revoke user access, such as when employees leave or access needs to be terminated. The API returns a 404 if no matching user is found. |
| `CARDLY_DELETE_WEBHOOK` | Delete Webhook | Tool to delete a webhook. Use after confirming the webhook ID to immediately cease all activity and event subscriptions for that webhook. |
| `CARDLY_ECHO_REQUEST` | Echo Request | Tool to echo all request parameters, body, and headers for debugging purposes. Use when validating authentication or testing API connectivity without affecting account data. |
| `CARDLY_GENERATE_PREVIEW` | Generate Preview | Tool to generate a low-quality, watermarked preview document for a card. Use after confirming artwork and template details to estimate costs and delivery. |
| `CARDLY_GET_ARTWORK` | Get Artwork | Tool to retrieve information on a specific piece of artwork by its unique ID. Use when you need to fetch detailed artwork data including preview images, media specifications, and metadata. The ID can be obtained from the List Artwork action. |

## 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 Cardly
```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=["cardly"])
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: ["cardly"] });
const tools = await session.tools();
```

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

Send a request, execute the Cardly 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": "Create a new contact list for holiday campaign"}],
)

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: "Create a new contact list for holiday campaign" }],
});

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 Cardly and read its MCP URL and headers
```python
from composio import Composio

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

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

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["cardly"],
  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 Cardly 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 Cardly tools.",
    tools=[],
    allowed_tools=["mcp__composio__*"],
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query("Create a new contact list for holiday campaign")
        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: "Create a new contact list for holiday campaign",
  stopWhen: stepCountIs(10),
});

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