Lattice MCP Server

Lattice MCP Server

An MCP (Model Context Protocol) server that exposes the Lattice Talent API as tools — so AI assistants like Claude can read and manage your people data, goals, feedback, reviews, and more.

Prerequisites

• Node.js 18+
• A Lattice API key (generate one from your Lattice admin dashboard under Integrations → API)

Quick Start

1. Clone & install

git clone https://github.com/EoinFalconer/lattice-mcp.git
cd lattice-mcp
npm install

2. Build

npm run build

3. Configure your MCP client

Add the server to your MCP client configuration. For example, in Claude Code (~/.claude/settings.json or project-level .mcp.json):

{
  "mcpServers": {
    "lattice": {
      "command": "node",
      "args": ["/absolute/path/to/lattice-mcp/dist/index.js"],
      "env": {
        "LATTICE_API_KEY": "your-api-key-here"
      }
    }
  }
}

For EMEA data residency, add "LATTICE_REGION": "emea" to the env block.
