RECOMMENDED RULE

The rule that runs sympy_repr_expr safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pypi:mcp Sympy, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sympy_repr_expr, this is the rule to start with:

sympy_repr_expr Allowed

sympy_repr_expr is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Pypi:mcp Sympy, apply this rule, and every sympy_repr_expr call is checked against it from then on.
