🚀 Quick Start

1. Installation

Clone the repository and install dependencies:

git clone https://github.com/onimsha/airtable-mcp-server-oauth.git
cd airtable-mcp-server-oauth
uv sync

2. Airtable OAuth Setup

1. Create an Airtable OAuth Application:
   • Visit Airtable Developer Hub
   • Create a new OAuth integration
   • Note your Client ID and Client Secret
   • Set redirect URI to http://localhost:8000/oauth/callback

3. Environment Configuration

Copy the environment template and configure your credentials:

cp .env.example .env

Edit .env with your values:

# Airtable OAuth Configuration
AIRTABLE_CLIENT_ID="your_airtable_client_id_here"
AIRTABLE_CLIENT_SECRET="your_airtable_client_secret_here"
AIRTABLE_REDIRECT_URI="http://localhost:8000/oauth/callback"

# Server Configuration
HOST="0.0.0.0"
PORT=8000
LOG_LEVEL="INFO"

4. Testing with MCP Inspector

Use the official MCP Inspector to test and interact with your server:

1. Start the server:

   uv run python -m airtable_mcp http

2. Open MCP Inspector: Visit https://modelcontextprotocol.io/docs/tools/inspector

3. Connect to your server:

   • Select "HTTP Streaming" transport
   • Enter the URL: http://localhost:8000/mcp
   • Click "Connect"

4. Authenticate with Airtable:

   • The server will guide you through OAuth authentication
   • Use the inspector to test available MCP tools

5. Run the Server

STDIO Transport (default):

uv run python -m airtable_mcp
# or
uv run airtable-oauth-mcp

HTTP Transport:

uv run python -m airtable_mcp http
# or with custom host/port
uv run python -m airtable_mcp http localhost 8001

Additional Options:

# Set log level
uv run python -m airtable_mcp --log-level DEBUG

# Show help
uv run python -m airtable_mcp --help

# Show version
uv run python -m airtable_mcp --version

The HTTP server will be available at http://localhost:8000/ (or custom host:port) with OAuth endpoints for web integration.

MCP Tools Available

The server provides 10 MCP tools for Airtable operations:

Base Operations:

• list_bases() - List all accessible bases
• list_tables(base_id, detail_level?) - List tables in a base
• describe_table(base_id, table_id) - Get detailed table schema

Record Operations:

• list_records(base_id, table_id, view?, filter_by_formula?, sort?, fields?) - List records with filtering
• get_record(base_id, table_id, record_id) - Get a specific record
• create_record(base_id, table_id, fields, typecast?) - Create a single record
• create_records(base_id, table_id, records, typecast?) - Create multiple records
• update_records(base_id, table_id, records, typecast?) - Update multiple records
• delete_records(base_id, table_id, record_ids) - Delete multiple records
• search_records(base_id, table_id, filter_by_formula, view?, fields?) - Search records with formulas

All tools now use typed parameters instead of generic args, making them more transparent to MCP clients.

Parameter Flexibility:

• fields parameter accepts either a single field name (string) or array of field names
• sort parameter expects array of objects: [{"field": "Name", "direction": "asc"}]

💡 Usage Examples

Basic Record Operations

# List all records in a table
records = await client.call_tool("list_records", {
    "base_id": "appXXXXXXXXXXXXXX",
    "table_id": "tblYYYYYYYYYYYYYY"
})

# Create a new record
new_record = await client.call_tool("create_record", {
    "base_id": "appXXXXXXXXXXXXXX",
    "table_id": "tblYYYYYYYYYYYYYY",
    "fields": {
        "Name": "John Doe",
        "Email": "[email protected]",
        "Status": "Active"
    }
})

# Search records with filtering
filtered_records = await client.call_tool("search_records", {
    "base_id": "appXXXXXXXXXXXXXX",
    "table_id": "tblYYYYYYYYYYYYYY",
    "filter_by_formula": "AND({Status} = 'Active', {Email} != '')",
    "fields": ["Name", "Email", "Status"]
})

Advanced Querying

# List records with sorting and filtering
records = await client.call_tool("list_records", {
    "base_id": "appXXXXXXXXXXXXXX",
    "table_id": "tblYYYYYYYYYYYYYY",
    "view": "Grid view",
    "filter_by_formula": "{Priority} = 'High'",
    "sort": [
        {"field": "Created", "direction": "desc"},
        {"field": "Name", "direction": "asc"}
    ],
    "fields": ["Name", "Priority", "Created", "Status"]
})

# Batch operations
batch_create = await client.call_tool("create_records", {
    "base_id": "appXXXXXXXXXXXXXX",
    "table_id": "tblYYYYYYYYYYYYYY",
    "records": [
        {"fields": {"Name": "Record 1", "Value": 100}},
        {"fields": {"Name": "Record 2", "Value": 200}},
        {"fields": {"Name": "Record 3", "Value": 300}}
    ],
    "typecast": True
})

Schema Discovery

# List all bases you have access to
bases = await client.call_tool("list_bases")

# Get detailed information about a specific table
table_info = await client.call_tool("describe_table", {
    "base_id": "appXXXXXXXXXXXXXX",
    "table_id": "tblYYYYYYYYYYYYYY"
})

# List all tables in a base
tables = await client.call_tool("list_tables", {
    "base_id": "appXXXXXXXXXXXXXX",
    "detail_level": "full"
})
