What is an Email MCP server?
An Email MCP server is essentially an email integration for AI. MCP stands for Model Context Protocol – an open standard that lets AI assistants use tools and external services. Sidemail’s Email MCP server is a program that translates Sidemail’s email features (sending emails, managing contacts and domains, etc.) into a format an AI like Claude or Cursor can use. In practice, it means you can prompt an AI to perform email tasks (send a message, add a contact, etc.), and the MCP server will carry out those actions via Sidemail’s API, then return the results to the AI.
How do I connect Sidemail’s Email MCP server in Claude Desktop?
Claude Desktop supports MCP servers through its settings. To use Sidemail’s server, you’ll need to add it to Claude’s config file. On Claude Desktop, open the configuration JSON and add an entry for Sidemail’s server. Read more in docs.
How do I set up the Sidemail Email MCP server in VS Code?
In VS Code, it’s very straightforward. Press Ctrl/Cmd + Shift + P to open the Command Palette, then start typing “MCP: Add Server”. Select that, choose “NPM Package” when prompted, and enter @sidemail/mcp as the package name. VS Code will install the Sidemail MCP server for you. When it asks, paste in your Sidemail API key. Once done, your VS Code AI (for example, using the built-in chat or Copilot Labs in agent mode) will have access to Sidemail’s email tools. Alternatively, you can configure the mcp.json manually as outlined in the docs, but the guided approach is easiest. Read more in docs.
Can I manage contacts and domains through the MCP server?
Yes – managing your subscriber lists and sender domains is a core part of Sidemail’s MCP server. There are tools for contacts (adding/updating contacts, querying contacts, deleting) and for groups (creating contact groups, listing them, etc.).
Are there any usage limits or extra costs for using the Email MCP server?
There’s no additional fee to use the Email MCP server. It’s included as part of the Sidemail service for all users.
