JMAP-MCP is a connector designed to interact with a JMAP (JSON Mail Access Protocol) server, allowing you to read emails via the Model Context Protocol (MCP). This project specifically demonstrates integration with a Fastmail JMAP server.
MCP Configuration
To use JMAP-MCP, you need to configure it as an mcpServer in your MCP configuration file. Here is an example configuration:
{
"mcpServers": {
"emails": {
"command": "npx",
"args": ["-y", "@jahfer/jmap-mcp-server"],
"env": {
"JMAP_SESSION_URL": "https://api.fastmail.com/jmap/session", // for example
"JMAP_TOKEN": "<your-jmap-token>"
}
}
}
}
API Token Configuration
You need to set your JMAP API token to authenticate with your email server (e.g., Fastmail). Obtain your API token from your server's settings.
Set the JMAP_SESSION_URL and JMAP_TOKEN environment variables when running the application.
Tools
Once configured in MCP, you can use commands or features within MCP that interact with the server definition to read your emails via the JMAP protocol.
