  Notion MCP integration with managed authentication. Query databases, create and update pages, manage blocks. Use this skill when users want to interact with Notion workspaces via MCP. For REST API, use the notion skill (https://clawhub.ai/byungkyu/notion-api-skill). For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

# Notion MCP

Access Notion via MCP (Model Context Protocol) with managed authentication.

## Quick Start

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'meeting notes', 'query_type': 'internal'}).encode()
req = urllib.request.Request('https://api.maton.ai/notion/notion-search', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

## Base URL

```
https://api.maton.ai/notion/{tool-name}
```

Maton proxies requests to `mcp.notion.com` and automatically injects your credentials. The `{tool-name}` corresponds to the MCP tool name (e.g., `notion-search`).

## Request Headers

MCP requests use the `Mcp-Session-Id` header for session management. If not specified, the gateway initializes a new session and returns the session ID in the `Mcp-Session-Id` response header. You can include this session ID in subsequent requests to reuse the same session.

## Authentication

All requests require the Maton API key:

```
Authorization: Bearer $MATON_API_KEY
```

**Environment Variable:** Set your API key as `MATON_API_KEY`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

### Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key

## Connection Management

Manage your Notion MCP connections at `https://api.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=notion&method=MCP&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Create Connection

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'notion', 'method': 'MCP'}).encode()
req = urllib.request.Request('https://api.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Get Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

**Response:**
```json
{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "PENDING",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "notion",
    "method": "MCP",
    "metadata": {}
  }
}
```

Open the returned `url` in a browser to complete OAuth authorization.

### Delete Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Specifying Connection

If you have multiple Notion connections (eg. OAuth2, MCP), you must specify which MCP connection to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'meeting notes', 'query_type': 'internal'}).encode()
req = urllib.request.Request('https://api.maton.ai/notion/notion-search', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If you have multiple connections, always include this header to ensure requests go to the intended account.

## Security & Permissions

- Access is scoped to pages, databases, blocks, and users within the connected Notion workspace.
- **All write operations require explicit user approval.** Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

## Code Examples

### JavaScript

```javascript
const response = await fetch('https://api.maton.ai/notion/notion-search', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${process.env.MATON_API_KEY}`
  },
  body: JSON.stringify({
    query: 'meeting notes',
    query_type: 'internal'
  })
});
const data = await response.json();
console.log(data);
```

### Python

```python
import os
import requests

response = requests.post(
    'https://api.maton.ai/notion/notion-search',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'query': 'meeting notes',
        'query_type': 'internal'
    }
)
print(response.json())
```

## Property Types Reference

When creating or updating pages in databases:

| Property Type | Format |
|---------------|--------|
| Title | `"Title Property": "Page Title"` |
| Text | `"Text Property": "Some text"` |
| Number | `"Number Property": 42` |
| Checkbox | `"Checkbox Property": "__YES__"` or `"__NO__"` |
| Select | `"Select Property": "Option Name"` |
| Multi-select | `"Multi Property": "Option1, Option2"` |
| Date (start) | `"date:Date Property:start": "2024-12-25"` |
| Date (end) | `"date:Date Property:end": "2024-12-31"` |
| Date (is datetime) | `"date:Date Property:is_datetime": 1` |
| Place (name) | `"place:Location:name": "Office HQ"` |
| Place (coordinates) | `"place:Location:latitude": 37.7749` |

**Special naming:** Properties named "id" or "url" must be prefixed with `userDefined:` (e.g., `"userDefined:URL"`).

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Missing MCP connection or invalid tool name |
| 401 | Invalid or missing Maton API key |
| 429 | Rate limited (10 req/sec per account) |

### Troubleshooting: API Key Issues

1. Check that the `MATON_API_KEY` environment variable is set:

```bash
echo $MATON_API_KEY
```

2. Verify the API key is valid by listing connections:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Troubleshooting: Invalid App Name

1. Ensure your URL path starts with `notion`. For example:

- Correct: `https://api.maton.ai/notion/v1/search`
- Incorrect: `https://api.maton.ai/v1/search`

## Notes

- All IDs are UUIDs (with or without hyphens)
- MCP tool responses wrap content in `{"content": [{"type": "text", "text": "..."}], "isError": false}` format
- The `text` field contains JSON-stringified data that should be parsed
- Use `notion-fetch` to get page/database structure before creating or updating pages
- For databases, fetch first to get the data source ID (`collection://...` URL)
