Q: What happens to my data when using this parser?

Your local .eml email files never leave your machine during the parsing phase. The local MCP process runs via stdio, extracting the sender, recipient, and body text on your own hardware. Claude Desktop only sends the cleaned text to the LLM for summarization, keeping your raw archives completely isolated from third-party APIs.

Parse raw EML files locally and let Claude Desktop summarize heavy email threads without chewing up your token limits.

Parse Raw Emails in Claude Desktop

The Email (.eml) File Parser exposes a single `parse_eml_file` tool to your AI client, converting messy MIME structures into clean JSON. You point it at an absolute local file path. It strips out the base64 attachments, HTML bloat, and custom headers that usually choke a context window. Claude Desktop reads the resulting sender, recipient, date, subject, and plain text body. You skip the manual copy-pasting and get straight to summarizing long corporate threads. This MCP Server runs locally on your machine, keeping your inbox archives entirely private while the agent does the heavy reading.

Drop Context Bloat Instantly

Raw email exports contain massive amounts of unreadable formatting data. Throwing a raw `.eml` file directly at an LLM wastes thousands of tokens on CSS tags and routing metadata. We built this tool to act as a mandatory filter. Your agent calls `parse_eml_file` before attempting to read anything. It gets back only the human-readable text and basic routing details. That means you save money on API calls and get faster responses when analyzing massive local email dumps.

Local Execution via MCP Server

Desktop integration means you keep your sensitive correspondence on your own hard drive. You configure the MCP server in your `claude_desktop_config.json` file using standard stdio transport. The parser runs as a subprocess alongside the app. There is no cloud API middleman reading your messages. You just download your `.eml` files from your mail provider, drop them in a local folder, and ask Claude to find specific project updates. The agent handles the extraction and formatting instantly.
