Granola

Granola

Access Granola's MCP server with managed OAuth authentication. Query meeting notes, list meetings, search meeting content, and retrieve transcripts.

Quick Start

# Query your meeting notes
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://gateway.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://gateway.maton.ai/granola/{tool_name}

Replace {tool_name} with the MCP tool name. The gateway proxies requests to Granola's MCP server at mcp.granola.ai and automatically handles OAuth authentication.

Authentication

All requests require the Maton API key in the Authorization header:

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 OAuth connections at https://ctrl.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=granola&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

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'granola'}).encode()
req = urllib.request.Request('https://ctrl.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

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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": "8a413c45-6427-45d9-b69d-8118ce62ffce",
    "status": "ACTIVE",
    "creation_time": "2026-02-24T11:34:46.204677Z",
    "last_updated_time": "2026-02-24T11:37:01.221812Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "granola",
    "metadata": {}
  }
}

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

Delete Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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, specify which one 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://gateway.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', '8a413c45-6427-45d9-b69d-8118ce62ffce')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

Code Examples

JavaScript

// Query meeting notes
const response = await fetch('https://gateway.maton.ai/granola/query_granola_meetings', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
    'Content-Type': 'application/json'
  },
  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

# List all meetings
response = requests.post(
    'https://gateway.maton.ai/granola/list_meetings',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={}
)
data = response.json()

# Get specific meeting content
meeting_ids = ['0dba4400-50f1-4262-9ac7-89cd27b79371']
response = requests.post(
    'https://gateway.maton.ai/granola/get_meetings',
    headers={

)

Notes

• MCP Protocol: Granola uses the Model Context Protocol (MCP). All tool calls are POST requests with JSON body parameters.
• Response Format: All responses follow MCP format with content array containing type: "text" objects and an isError boolean.
• Access Control: Users can only query their own meeting notes. Shared notes from others are not accessible.
• Free Tier Limits: Basic (free) plan users are limited to notes from the last 30 days.
• Transcript Access: The get_meeting_transcript tool is only available on paid Granola tiers.
• Rate Limits: Approximately 100 requests per minute (varies by plan tier).
