How to use
flagpost is an MCP server that lets your AI assistant read, search, and edit files in a directory you allow.
- Best for giving an assistant safe access to a local project or document folder.
- Works in any MCP-compatible client — Claude Desktop, Claude Code, Cursor, and others.
- Add it once to your client config; its tools then appear to the assistant automatically.
