Measured tools (8)

• list_products read-only

  List every product in the Business Suite line with its included skills. FREE. Takes no arguments. Typical input {} returns a list of 30 product objects, each {"slug": "smb-ops-desk", "name": ..., "tagline": ..., "skills": ["Skill A", ...], "free_skill": "Gateway Skill Name"}. Use the returned slug values with get_free_skill, get_full_product, or get_full_skill. Returns metadata only - no persona text and no skill instructions. Use when the caller wants to see what this server covers. Not for keyword search across the whole 138-product catalog, which the catalog server's search_catalog does, and not for instructions the caller can act on (get_free_skill). Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

• get_free_skill read-only

  Load a product's free gateway skill with its complete instructions. FREE. Typical input {"slug": "smb-ops-desk"} returns {"slug": "smb-ops-desk", "skill": "<skill name>", "instructions": "<full skill text>"}. Returns exactly one skill - the product's free gateway skill - chosen automatically from the slug, with no plan required. Use when the caller wants usable instructions immediately. Not for the product's other skills: those are named and need get_full_skill with a skill_name, which requires a paid plan. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'. Use list_products."}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

  Parameters:

  • slug (required) — string — Product slug exactly as returned by list_products, e.g. "smb-ops-desk"; must be non-empty.

• unit_economics read-only

  Calculate unit economics: margin, break-even, LTV:CAC, and a plain reading. FREE. Typical input {"price": 49, "unit_cost": 12, "fixed_costs_monthly": 8000} returns {"unit_margin": 37.0, "margin_pct": 75.5, "markup_pct": 308.3, "breakeven_units_per_month": 216.2, "reading": ["..."]}. LTV fields appear when cac is provided. Use when price, variable cost, and fixed costs are known and margin or break-even is the question. Not for cash position over time (cash_runway) and not for solving backward from a target margin (target_price). Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "price must be > 0"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

  Parameters:

  • price (required) — number — Selling price per unit; must be greater than 0, e.g. 49.0.
  • unit_cost (required) — number — Variable cost per unit, in the same currency as price, e.g. 12.0.
  • cac — number — Customer acquisition cost; a value greater than 0 enables LTV and LTV:CAC. Default 0 (skipped).
  • units_per_month — number — Expected sales volume per month; a value greater than 0 enables the monthly profit projection. Default 0 (skipped).
  • fixed_costs_monthly — number — Fixed monthly costs; a value greater than 0 enables the break-even calculation. Default 0 (skipped).
  • purchases_per_customer — number — Average lifetime purchases per customer used for LTV. Default 1.

• get_full_product read-only

  Load one product in full: its persona plus every paid skill. PREMIUM (license). Typical input {"slug": "smb-ops-desk"} returns {"slug": ..., "name": ..., "persona": "<persona text>", "skills": [{"name": ..., "instructions": ...}, ...], "free_skill": {...}}. Returns persona plus every skill for one product. Use when the caller wants the whole product. Not for a single skill (get_full_skill) and not for a free look, which list_products and get_free_skill provide with no plan. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

  Parameters:

  • slug (required) — string — Product slug exactly as returned by list_products, e.g. "smb-ops-desk"; must be non-empty.

• get_full_skill read-only

  Load one paid skill's complete instructions from a product. PREMIUM (license). Typical input {"slug": "smb-ops-desk", "skill_name": "invoice-chaser"} returns {"slug": ..., "skill": ..., "instructions": "<full skill text>"}. Returns one named skill, selected by skill_name. Use when the caller wants one specific paid skill. Not for the free gateway skill, which get_free_skill returns with no plan, and not for every skill at once (get_full_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

  Parameters:

  • slug (required) — string — Product slug exactly as returned by list_products, e.g. "smb-ops-desk"; must be non-empty.
  • skill_name (required) — string — Exact skill name as listed in that product's "skills" array from list_products, e.g. "invoice-chaser"; must be non-empty.

• loan_payment read-only

  Compute an amortized loan payment: monthly payment, total paid, total interest. FREE. Administrative math only, not financial advice. Typical input {"principal": 250000, "annual_rate_pct": 6.5, "years": 30} returns {"monthly_payment": 1580.17, "months": 360, "total_paid": ..., "total_interest": ...}. Use for a fixed-rate amortized loan. Not for interest-free schedules - the merchant server's installment_plan splits a total without interest. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "principal and years must be > 0"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

  Parameters:

  • principal (required) — number — Loan amount; must be greater than 0, e.g. 250000.
  • annual_rate_pct (required) — number — Annual interest rate as a percentage, 0 to 100, e.g. 6.5 for 6.5%.
  • years (required) — number — Loan term in years; must be greater than 0; fractions allowed, e.g. 30.

• cash_runway read-only

  Compute months of cash runway and the projected out-of-cash date. FREE. Typical input {"cash_balance": 120000, "monthly_burn": 15000, "monthly_revenue": 5000} returns {"runway_months": 12.0, "net_burn_monthly": 10000, "projected_out_of_cash": "YYYY-MM-DD"}; when revenue covers burn it returns {"runway": "infinite at current numbers (revenue covers burn)", ...}. Use when a cash balance and a monthly burn are known. Not for per-unit profitability (unit_economics). Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "cash_balance must be >= 0"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

  Parameters:

  • cash_balance (required) — number — Cash on hand today; must be 0 or greater, e.g. 120000.
  • monthly_burn (required) — number — Total monthly outflow in the same currency as cash_balance, e.g. 15000.
  • monthly_revenue — number — Monthly inflow netted against burn, e.g. 5000. Default 0.

• target_price read-only

  Compute the selling price needed to hit a target margin percentage. FREE. Typical input {"unit_cost": 12, "target_margin_pct": 60} returns {"required_price": 30.0, "unit_margin": 18.0, "equivalent_markup_pct": 150.0}. The inverse of unit_economics - solves for price from a target margin. Use when the margin is the fixed requirement. Not when the price is already set. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "target_margin_pct must be between 0 and 100"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

  Parameters:

  • unit_cost (required) — number — Variable cost per unit; must be 0 or greater, e.g. 12.0.
  • target_margin_pct (required) — number — Desired gross margin percentage, strictly between 0 and 100, e.g. 60 for a 60% margin.
