granola-api（granola API 搜索）

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.

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.

Security & Permissions

• Access is scoped to meeting notes, transcripts, and documents within the connected Granola account.
• 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

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'

    }
)
print(response.json())

Error Handling

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

1. 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:

• Correct: https://api.maton.ai/granola/query_granola_meetings
• Incorrect: https://api.maton.ai/query_granola_meetings

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: [\
  {\
    \"code\": \"invalid_type\",\
    \"expected\": \"array\",\
    \"received\": \"undefined\",\
    \"path\": [\"meeting_ids\"],\
    \"message\": \"Required\"\
  }\
]"
    }
  ],
  "isError": true
}

Notes

• All IDs are UUIDs (with or without hyphens)
• MCP tool responses wrap content in {"content": [{"type": "text", "text": "..."}], "isError": false} format
• Users can only query their own meeting notes; shared notes from others are not accessible
• Basic (free) plan users are limited to notes from the last 30 days
• The get_meeting_transcript tool is only available on paid Granola tiers
