Security Notes
The server performs extensive local file system operations (read/write) based on user-provided paths for `rootDir`, `filePath`, `producerDir`, `consumerDir`, and `projectDir`. While `path.resolve` is used for normalization, an attacker with local access and appropriate file system permissions could exploit path traversal vulnerabilities (e.g., using `../../`) to read or modify files outside the intended project directories, especially with `addContractComments` (which modifies source files) and `init_project` (which creates project structures). The `json_schema` parser reads arbitrary JSON files, which could lead to denial-of-service if extremely large or malformed JSON is supplied. Communication is via standard I/O (stdio), which limits direct network exposure, but careful handling of user input is critical if integrated into other services.
