Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
The GitHub repo last changed 16 days ago, and the latest version (0.1.0) reached the registry 16 days ago.

calcport does arithmetic safely. Its centrepiece is an expression evaluator that understands the usual operators, parentheses, a handful of functions, and the constants pi and e — and nothing else. The evaluator is a hand-written parser, so an expression can never turn into code execution, a shell call, or a property lookup. Around it sit four single-purpose operations for callers that just need one sum, difference, product, or quotient.
npx @reneturcios/calcport calculate "2+3*4"
Or run the container image:
docker run -i ghcr.io/cloudcorprecords/calcport
The container defaults to the MCP server (see below). Pass CLI arguments to use it as a CLI instead.
# Evaluate an expression
calcport calculate "sqrt(3^2 + 4^2) + pi"
calcport add 2 3 # 5 calcport subtract 10 4 # 6 calcport multiply 2.5 4 # 10 calcport divide 7 2 # 3.5
calcport calculate "2^10" --json calcport add 2 3 --json
calcport --version
Expressions may use + - * / % ^, parentheses, unary minus, the functions sqrt, abs, floor, ceil, and round, and the constants pi and e. ^ is right-associative, so 2^3^2 is 512.
Exit codes: 0 on success, 1 when a calculation cannot be done (division by zero, a malformed expression — the error says why), 2 for usage errors.
One bin serves both faces. The mcp subcommand starts a stdio MCP server:
npx -y @reneturcios/calcport mcp
MCP client configuration:
{
"mcpServers": { "calcport": { "command": "npx", "args": ["-y", "@reneturcios/calcport", "mcp"] } } }
| Tool | Input | What it returns |
|---|---|---|
calculate | expression (string, required) | The numeric result of the expression, with the expression echoed back. |
add | a, b (numbers, required) | a + b, with both operands. |
subtract | a, b (numbers, required) | a - b, with both operands. |
multiply | a, b (numbers, required) | a * b, with both operands. |
divide | a, b (numbers, required) | a / b, with both operands. Dividing by zero is an error. |
