MCP-SERVER

The server directly accesses properties of the loaded JSON database object using user-provided 'table' and 'field' values (e.g., db[table], r[field]). While inputSchema is defined for these tools, the handler functions themselves do not perform explicit sanitization or restrictive type checking on these inputs. If an attacker can provide values like '__proto__' or 'constructor' for 'table' or 'field' (e.g., by bypassing or exploiting a flaw in the Model Context Protocol SDK's input validation), it could potentially lead to prototype pollution, arbitrary object property manipulation, or unexpected behavior. This poses a significant security risk if the server is exposed to untrusted input without robust external validation. Additionally, the server reads the entire 'db.json' file on every tool call, which could be a performance bottleneck for large files.
