Granola

Granola MCP

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

Quick Start

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'What action items came from my last meeting?'}).encode()
req = urllib.request.Request('https://api.maton.ai/granola/query_granola_meetings', 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/granola/{tool-name}

Maton proxies requests to mcp.granola.ai and automatically injects your credentials. The {tool-name} corresponds to the MCP tool name (e.g., query_granola_meetings).

Authentication

All requests require the Maton API key:

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai 2. Go to maton.ai/settings 3. Copy your API key

Connection Management

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

List Connections

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:

{
  "connection": {
    "connection_id": "{connection_id}",

Delete Connection

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 Granola connections, you must specify which MCP connection to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'What were my action items?'}).encode()
req = urllib.request.Request('https://api.maton.ai/granola/query_granola_meetings', 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.

Code Examples

JavaScript

const response = await fetch('https://api.maton.ai/granola/query_granola_meetings', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': Bearer ${process.env.MATON_API_KEY}
  },
  body: JSON.stringify({
    query: 'What were the action items from my last meeting?'
  })
});
const data = await response.json();
console.log(data.content[0].text);

Python

import os
import requests
Query meeting notes
response = requests.post(
    'https://api.maton.ai/granola/query_granola_meetings',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'query': 'What were the action items from my last meeting?'
    }
)
print(response.json())

Error Handling

| Status | Meaning | |--------|---------| | 400 | Missing Granola connection | | 401 | Invalid or missing Maton API key | | 429 | Rate limited (approx 100 req/min) |

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

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

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 granola. For example:

Troubleshooting: MCP Parameter Errors

MCP tools return validation errors when required parameters are missing:

{
  "content": [
    {
      "type": "text",
      "text": "MCP error -32602: Input validation error: Invalid arguments for tool get_meetings: [\n  {\n    \"code\": \"invalid_type\",\n    \"expected\": \"array\",\n    \"received\": \"undefined\",\n    \"path\": [\"meeting_ids\"],\n    \"message\": \"Required\"\n  }\n]"
    }
  ],
  "isError": true
}
