- Find USGS water monitoring sites in a state. Returns a list of monitoring stations with their site numbers, names, and locations. Use site numbers with get_water_levels to retrieve data. Args: state: Two-letter US state abbreviation (e.g. 'CA', 'TX'). site_type: Type of monitoring site. 'ST' for stream/river, 'GW' for groundwater well, 'SP' for spring. limit: Maximum number of sites to return (default 50).ConnectorNo auth
- Resets the funnel analytics of one webinar, for example after test registrations polluted the numbers. `scope` window reopens only the current show window, lifetime wipes all daily and touch statistics. Side effect: the numbers are gone from the site and cannot be restored; registrants, emails and the campaign itself are NOT touched. Needs `session_id`, `webinar_id`, `scope` and a clear yes (`confirm` true). Say which of the two scopes it is and what is lost before you write, and read the numbers with wi_get_webinar_funnel_conversion_stats before and after.ConnectorDestructiveNo auth

- The profit or loss and the ROI percentage from an initial investment and a final value (ROI = (final - initial) / initial x 100). Negative results are valid. It is not annualized. Use for questions about the total percentage return on money put in, from two values. Do not use for a return per year (use the CAGR calculator at smartfin.fyi/cagr-calculator.html), for what a real stock returned (use smartfin_calculate_investment_return), or for fees and taxes: include them in the final value yourself.ConnectorNo auth
- Runs one calculator from list_calculators on your numbers and returns the headline result, the supporting figures, a one-sentence reading, and a link that opens the calculator with the same inputs. Missing inputs use the calculator's example values. Enter percents as points (15 means 15%), choices as the option index.ConnectorNo auth
- Generates a CSS clamp() declaration (in rem) that linearly interpolates a size between a value at a small viewport width and a value at a large one, exactly matching GO AI's clamp() calculator tool (same slope/intercept math, rounded to 4 decimal places). Returns a status: 'sameViewports' when the two viewport widths are equal (no line can be drawn -- css is null), 'flat' when the min and max sizes are equal (a constant, clamp() unneeded), 'inverted' when the max size is smaller than the min (still valid CSS, but the computed size shrinks as the viewport grows), or 'ok' otherwise. Optionally evaluates the computed pixel size at a list of preview viewport widths, and optionally generates a matched fluid type scale by multiplying both endpoints by ratio^step for a given number of steps -- unlike the website's five-option dropdown, any positive ratio is accepted here since the underlying math is not limited to those presets.ConnectorNo auth
- Estimate the monthly home-loan EMI / monthly payment in India — a home-loan calculator. Deterministic math; not advice or a loan-approval claim. Two modes: pass propertyValue (80% LTV assumed) OR loanAmount for a specific loan (e.g. "₹50 lakh loan"). Use for "what would my EMI be" / "monthly payment on …". The response `assumptionNote` states the basis in plain words. Always surface the disclaimer field.ConnectorNo auth
- OathReady's physical-presence calculator for Canadian citizenship eligibility (the 1,095-days-in-5-years rule, including the pre-PR half-day credit capped at 365). Dates are YYYY-MM-DD. Returns eligibility as of the application date plus any shortfall. This is an estimate, not legal advice; the full interactive calculator is at https://oathready.ca/presence-calculator?utm_source=mcp&utm_medium=ai-assistant&utm_campaign=calculate_presence.ConnectorNo auth
- Ayadi shadvarga calculator for a building or a room: send the dimensions and the API returns all six proportional formulas with the multiplier, the divisor and the remainder shown, the member each remainder names, and the two verdict rules the texts state. Choose between three text families, which genuinely disagree, and choose your own cubit length, because every remainder is unit sensitive. Built for practitioner tools, plan checking software and anyone who has to justify a dimension rather than assert it.ConnectorNo auth
- Batch-screen a list of IMO numbers and wait for the results (up to two minutes). Returns one verdict per hull plus the batch status. Needs ARCNAUTICAL_API_KEY. Each hull spends one screening unit unless it was already screened today.ConnectorNo auth
- Solve a right-angle triangle from any two given values, at least one of which must be a side. Sides: a (opposite), b (adjacent), c (hypotenuse). angleA is angle A in degrees, between 0 and 90 (the third angle is the 90 degree right angle). Returns all three sides, both non-right angles, the area and the perimeter. Source: https://hopi.co.uk/triangle-calculator/ConnectorNo auth
