Security profile

Claimed and verified servers get a weekly static scan that shows what the code can reach: external services, environment variables, shell commands, agent configuration folders, plus any dependencies with known advisories. Claim this listing to get one. How the security profile works

Documented tools (5)

From project documentation. A server handshake does not verify each tool’s description or behavior.

get_calculator_info

Get detailed info about a calculator — inputs with units/defaults, outputs, and the formula used.

list_calculators

List available calculators, optionally filtered by category.

list_simulation_tools

List all 13 available simulation tools with their jobType identifiers and parameter reference.

run_calculation

Run a calculator with specific inputs. Returns results with units and a link to the interactive version on rftools.io. Runs locally — instant, no quota consumed.

run_simulation

Submit a simulation job and wait for the result. Returns the full result JSON along with a link to the interactive results page on rftools.io.
