Filesystem Operations Tool Server With Sandboxed Access Control

via “filesystem operations with sandboxed path validation and built-in tools”

Agent harness built with LangChain and LangGraph. Equipped with a planning tool, a filesystem backend, and the ability to spawn subagents - well-equipped to handle complex agentic tasks.

Unique: Filesystem tools are integrated into the agent's tool registry with automatic path validation at the LangGraph node level, preventing malicious tool calls before they reach the filesystem. Validation happens before LLM sees the tool schema, not after tool invocation.

vs others: More secure than giving agents raw filesystem access because validation is enforced at the framework level rather than relying on the LLM to use tools correctly, and error messages are sanitized to prevent information leakage.
