FileMaker Data API MCP Server

A Model Context Protocol (MCP) server that provides AI agents with direct access to FileMaker databases through the FileMaker Data API. Compatible with Claude Desktop, Claude Code Console, Windsurf, Cursor, Cline, and other MCP-enabled AI assistants.

What It Does

This MCP server acts as a bridge between AI agents and FileMaker databases, enabling natural language interactions with your FileMaker data and database structure:

Data Interaction

• Query databases - Retrieve, search, and analyze FileMaker records
• Manage records - Create, update, delete, and duplicate records through conversation
• Execute scripts - Run FileMaker scripts with parameters
• Upload files - Add files to container fields (including repetitions)
• Set global fields - Manage FileMaker global fields programmatically
• Multi-database support - Switch between different FileMaker databases dynamically

Database Introspection

• Discover structure - AI agents can introspect database schemas, layouts, and field definitions
• Understand relationships - Access portal and related table information
• Architect solutions - Enable AI to design and implement FileMaker applications through natural language
• Metadata access - Get complete information about layouts, fields, value lists, and scripts

This introspection capability allows AI agents to understand your database architecture and help you build, modify, and optimize FileMaker solutions through simple conversation.

Quick Start

Installation

npm install -g filemaker-data-api-mcp

Setup

# Add your FileMaker connection
filemaker-mcp config add-connection production \
  --server 192.168.0.24 \
  --database Sales \
  --user admin \
  --password your_password

# Set as default
filemaker-mcp config set-default production

Configure Your AI Agent

Claude Desktop

Edit your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "filemaker": {
      "command": "filemaker-mcp",
      "args": ["start"]
    }
  }
}

Windsurf / Cursor / Cline

Add to your MCP settings configuration:

{
  "mcpServers": {
    "filemaker": {

• ✅ Metadata - Access database, layout, and script information
• ✅ Container fields - Upload files (including repetitions)
• ✅ Global fields - Set global field values

Usage Examples

Example 1: Query Your Database

You ask:

"Show me all contacts from the production database"

The AI agent automatically connects and retrieves the data.

Example 2: Database Introspection

You ask:

"What is the structure of the Contacts layout? Show me all fields and their types."

The AI agent introspects the database schema and provides detailed field information.

Example 3: Switch Between Databases

You ask:

"Compare sales records from production and staging databases"

The AI agent switches between connections and compares the data.

Example 4: Create Records

You ask:

"Add a new contact: John Smith, john@example.com, 555-1234"

The AI agent creates the record with the provided information.

Example 5: Ad-hoc Connection

You ask:

"Connect to 192.168.0.26, database TestDB, user admin, password test123. Show all records."

The AI agent connects with inline credentials and queries the database.

Example 6: Solution Architecture

You ask:

"Design a customer management system with contacts, orders, and products. Create the layouts and suggest field definitions."

The AI agent uses database introspection to understand your current structure and helps architect the solution.

Configuration

CLI Commands

# Initial setup
filemaker-mcp setup

# Connection management
filemaker-mcp config add-connection <name> [options]
filemaker-mcp config remove-connection <name>
filemaker-mcp config list-connections

Environment Variables

You can also configure via environment variables in the Claude Desktop config:

{
  "mcpServers": {
    "filemaker": {
      "command": "filemaker-mcp",
      "args": ["start"],
      "env": {
        "FM_SERVER": "192.168.0.24",
        "FM_DATABASE": "Sales",
        "FM_USER": "admin",
        "FM_PASSWORD": "your_password",
        "FM_VERSION": "vLatest"
      }
    }
  }
}

Configuration Priority
