About Nylas API MCP Server

What is Nylas API MCP Server: Next-Gen AI Context Mastery & API Innovation?

This experimental server bridges the Nylas API ecosystem with AI-driven tools through the Model Context Protocol (MCP). Acting as a middleware layer, it empowers developers to seamlessly integrate email, calendar, and contact management features using advanced AI context handling. By standardizing access to Nylas resources, it enables applications like Claude Desktop and Cursor to leverage contextual data and automation workflows without manual API configuration.

How to use Nylas API MCP Server: Next-Gen AI Context Mastery & API Innovation?

Start by installing Node.js 18+, then clone the repository and execute:

npm install && npm run build

Run in stdio mode for direct AI tool integration:

npm start

For remote access, enable HTTP mode with:

MCP_MODE=http npm start

Configure client apps like Cursor by pointing to the server process, then access pre-built prompts and code generators directly within your AI workflow.

Nylas API MCP Server (Experimental)

Note : This project is experimental and is intended as an exploration of using the Model Context Protocol (MCP) as a guide for Nylas API integrations. It is not official and should be used for learning and experimentation purposes only.

This project implements a Model Context Protocol (MCP) server for the Nylas API. It provides resources, tools, and prompts to help developers learn about and integrate with the Nylas API for email, calendar, and contacts functionality.

What is MCP?

The Model Context Protocol (MCP) is a standard for integrating data, tools, and prompts with AI applications. MCP servers can expose resources, tools, and prompts to AI applications like Claude Desktop, Cursor, and other MCP-compatible applications.

Features

This MCP server provides:

Documentation Resources : Comprehensive documentation about Nylas API endpoints, authentication, and best practices
Code Samples : Ready-to-use code samples for various Nylas API operations in multiple languages (Node.js, Python, Java, Ruby, curl)
Interactive Tools : Tools to generate authentication code and endpoint-specific implementation code
Prompts : Pre-built prompts for common Nylas integration scenarios

Getting Started

Prerequisites

Node.js 18+
npm

Installation

Clone this repository
Install dependencies

npm install

Build the project

npm run build

Running the MCP Server

Using stdio (for direct integration with MCP clients)

npm start

Using HTTP with SSE (for remote connections)

MCP_MODE=http npm start

By default, the HTTP server runs on port 3000. You can change this by setting the PORT environment variable:

MCP_MODE=http PORT=8080 npm start

Using with MCP Clients

Claude Desktop

Start the MCP server in stdio mode
In Claude Desktop, go to Settings > Servers
Click "Add Server"
Select "Run a local command" and enter the command to start this server:

node /path/to/nylas-api-mcp/dist/index.js

Give it a name (e.g., "Nylas API")
After adding, you can use all the Nylas API resources, tools, and prompts in your Claude conversations

Cursor

Start the MCP server in stdio mode
In Cursor, add a new MCP server in the settings
Configure it to use the command:

node /path/to/nylas-api-mcp/dist/index.js

Resources

This MCP server provides the following resources:

General Documentation : Overview of Nylas API capabilities
Authentication Guide : How to authenticate with Nylas API
API Endpoints : Documentation for email, calendar, contacts, and webhook endpoints
Code Samples : Usage examples in multiple programming languages

Tools

Interactive tools for code generation:

generate-auth-code : Generates authentication code in your preferred language
