GenPark Safe Eval Expression AST Sandbox
LocalAbout GenPark Safe Eval Expression AST Sandbox
A Python library and MCP server that safely evaluates and validates mathematical and boolean expressions using an AST, preventing arbitrary code execution. It has no third-party runtime dependencies.
Key features
- 01Evaluate mathematical expressions
- 02Evaluate boolean expressions
- 03Validate expressions using an AST
- 04Prevent arbitrary code execution
Use cases
- 01Evaluate user-provided math expressions safely
- 02Validate boolean expressions before use
MCP support
Runs as an MCP server and exposes safe expression evaluation and validation to MCP clients. It can also be used directly as a Python library.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
