An MCP server that parses HAR files and returns requests in a simplified format
Mcp har server mcp server connects MCP Har Server to AI assistants that speak the Model Context Protocol. An MCP server that parses HAR files and returns requests in a simplified format.
A Model Context Protocol (MCP) server that parses HAR (HTTP Archive) files and displays requests in a simplified format. This tool is designed to be used with AI assistants through the MCP protocol.
This tool uses the Model Context Protocol (MCP), which allows AI assistants to interact with external tools and services. Learn more about MCP at https://github.com/modelcontextprotocol/typescript-sdk.
Once connected, the assistant can call these 6 tools directly:
macOS — ~/Library/Application Support/Claude/claude_desktop_config.jsonWindows — %APPDATA%\Claude\claude_desktop_config.jsonhar_viewer — Displays HAR file requests in a simplified format with hash identifiers. Includes filtering options to narrow down resultshar_detail — Provides detailed information about specific HAR file entries including headers and request/response bodies. Uses hash identifiers to reference specificdomain_list — Lists all unique domains found in a HAR file to help reduce output volume and provide filtering optionsInstallation — The Installation tool exposed by this serverSetup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. MCP Har Server sits in that group, and the shape of its toolset — macOS, Windows, har_viewer among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
