MCP server for exact arithmetic: a single safe calculator tool over an AST allowlist, with no unbounded dependencies.

How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.
| Tool | Risk | Side effects | Approval |
|---|---|---|---|
| calculate Evaluate an arithmetic expression and return the result.
Args:
expression: The expression to evaluate, for example "2 + 3 * (4 - 1)",
"sqrt(16) + sin(pi/2)" or "123456789 * 987654321". `^` is accepted
as a power operator, and `×` and `÷` as multiply and divide.
