filesystem-mcp

The server directly manipulates the local filesystem, which inherently carries significant security implications if the controlling agent is compromised or misused. However, the provided source code does not contain direct 'eval' or arbitrary command execution vulnerabilities. File operations are performed using standard Node.js `fs/promises` APIs, and input parameters are validated via Zod schemas. Path expansion using `os.homedir()` limits path traversal risks to the user's home directory context. The `str_replace` tool specifically checks for unique occurrences, mitigating risks of unintended broad replacements. While the implementation appears robust for its stated purpose, the powerful nature of direct filesystem access necessitates deployment in a trusted environment with a thoroughly vetted controlling agent.
