Perform basic arithmetic and random number generation inside MCP workflows.
The tool is described as providing only basic arithmetic and random number generation, with no declared secrets or remote network endpoints. Overall risk appears low from the materials, but as a third-party registry open-source project with weak adoption and unclear maintenance, its actual implementation should still be verified carefully.
The materials explicitly state that no keys or environment variables are required. There is no indication of account, API token, or other sensitive credential use, so credential leakage or abuse exposure appears minimal.
The materials declare no remote endpoints, and the described functionality is limited to local arithmetic and random number generation. Based on the provided information, there is no evidence of user data being sent out over the network.
The system checks indicate that this MCP tool can execute code or spawn processes. For an MCP tool, this is a normal capability; the current materials do not show requests for system privileges beyond its calculator-like purpose, but the runtime environment should still be constrained and the exposed tool interfaces verified.
The description does not state any need to read or write local files, databases, the clipboard, or other user resources. From the materials, the data access scope appears narrow, with no signs of overbroad access.
A public source repository is available for review, which is a positive factor. However, it comes from a third-party registry, has no declared license, zero stars, unknown maintenance status, and no README, making auditability and maintenance signals relatively weak; code and dependencies should be reviewed before use.
