About

Reference MCP server from Anthropic for secure local filesystem access. Lets the model list directories, read file contents, create/edit files, and search across a configured set of allowed paths. The allow-list is enforced at the server boundary — paths outside it are rejected — so an agent can operate inside a project root without reaching the rest of the disk. Most-installed reference server in the ecosystem.
