Effect Airtable MCP Server

A production-ready Model Context Protocol server for Airtable, built with Effect for type-safe, composable, and robust API interactions. This server enables programmatic management of Airtable bases, tables, fields, and records through Claude Desktop or other MCP clients.

Why Effect?

This server leverages the Effect library to provide:

  • Type Safety: Full end-to-end type safety from input validation to output serialization
  • Error Handling: Structured error types with automatic validation and retries
  • Composability: Modular tool architecture with reusable validation pipelines
  • Testability: Pure functions and Effect-based testing without mocking
  • Reliability: Contract-driven design catches API changes at validation boundaries

Unlike traditional implementations, this server features:

  • Staged Table Creation: Builds complex tables incrementally to minimize API failures
  • Schema Validation: Zod schemas ensure correctness at runtime
  • Automatic Retries: Effect-based retry logic for transient failures
  • Developer Experience: Comprehensive error messages and type inference

Requirements: Node.js

  1. Install Node.js (version 18 or higher) and npm from nodejs.org
  2. Verify installation: 
    node --version
npm --version

⚠️ Important: Before running, make sure to setup your Airtable API key

Obtaining an Airtable API Key

  1. Log in to your Airtable account at airtable.com
  2. Create a personal access token at Airtable's Builder Hub
  3. In the Personal access token section select these scopes:
    • data.records:read
    • data.records:write
    • schema.bases:read
    • schema.bases:write
  4. Select the workspace or bases you want to give access to the personal access token
  5. Keep this key secure - you'll need it for configuration

Installation

Method 1: Using npx (Recommended)

  1. Navigate to the Claude configuration directory:

    • Windows: C:\Users\NAME\AppData\Roaming\Claude
    • macOS: ~/Library/Application Support/Claude/

    You can also find these directories inside the Claude Desktop app: Claude Desktop > Settings > Developer > Edit Config

  2. Create or edit claude_desktop_config.json:

{
  "mcpServers": {
    "airtable-effect": {
      "command": "npx",
      "args": ["@kastalien-research/effect-airtable-mcp"],
      "env": {
        "AIRTABLE_API_KEY": "your_api_key_here"
      }
    }
  }
}

Note: For Windows paths, use double backslashes (\) or forward slashes (/).

Method 2: Local Development Installation

If you want to contribute or modify the code:

# Clone the repository
git clone https://github.com/glassBead-tc/effect-airtable-mcp.git
cd effect-airtable-mcp

# Install dependencies
npm install

# Build the server
npm run build

# Run tests
npm test

# Run locally
node build/index.js

Then modify the Claude Desktop configuration file to use the local installation:

{
  "mcpServers": {
    "airtable-effect": {
      "command": "node",
      "args": ["/absolute/path/to/effect-airtable-mcp/build/index.js"],
      "env": {
        "AIRTABLE_API_KEY": "your_api_key_here"
      }
    }
  }
}

Verifying Installation

  1. Start Claude Desktop
  2. The Airtable MCP server should be listed in the "Connected MCP Servers" section
  3. Test with a simple command:
List all bases

Architecture

Effect-Based Design

This server uses a contract-driven architecture powered by Effect:

// Every tool follows this pattern:
ToolExecutor {
  1. Validate Input (Zod schema)
  2. Execute Operation (Effect workflow)
  3. Validate Output (Zod schema)
  4. Check Postconditions (business rules)
  → Return typed result or structured error
}

Key Components:

  • ToolExecutor: Generic execution framework with validation pipeline
  • mcp-adapter: Bridges Effect workflows to MCP protocol
  • Schema Modules: Zod schemas for all inputs/outputs (bases, tables, fields, records)
  • Tool Modules: Pure Effect-based operations with no side effects until execution

Error Handling:

  • InputValidationError: Invalid tool arguments
  • OutputValidationError: Unexpected API response (catches breaking changes)
  • AirtableApiError: HTTP errors with context and retry logic
  • PostconditionError: Business rule violations

See for detailed documentation.
