Hashfile offers a powerful Model Context Protocol (MCP) server designed to give AI agents surgical precision over file editing and ironclad control over file access. It addresses the common problem of line-number-based editing failures by implementing content-anchored operations, where every line is tagged with a content hash, ensuring edits target the *right content* regardless of file changes. This server also introduces AGENTS.md, a declarative system for granular access control, allowing developers to forbid access to secrets, establish read-only permissions for critical files, and ignore irrelevant build artifacts or dependencies from AI context. With full compatibility for standard MCP filesystem tools, Hashfile provides a reliable and secure foundation for AI-driven development workflows.
