loan_paymentCompute an amortized loan payment: monthly payment, total paid, total interest.1 finding
Why it is in this group
- The name "loan_payment" says "payment": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Findings
- Warn
The server marks "loan_payment" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".
What this check looks forMatched text
annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "loan_payment" says "payment": a word that usually means money moves, which cannot be taken back.
Description, as the server wrote it 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.

cash_runwayCompute months of cash runway and the projected out-of-cash date.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it 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.
Annotations the server declares
- title: Cash Runway

- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
target_priceCompute the selling price needed to hit a target margin percentage.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it 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.
Annotations the server declares
- title: Target Price

unit_economicsCalculate unit economics: margin, break-even, LTV:CAC, and a plain reading.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it 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.

get_free_skillLoad a product's free gateway skill with its complete instructions.No findings
Why it is in this group
- The name "get_free_skill" says "get": a word for reading.
Description, as the server wrote it 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.

get_full_productLoad one product in full: its persona plus every paid skill.No findings
Why it is in this group
- The name "get_full_product" says "get": a word for reading.
Description, as the server wrote it 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.

get_full_skillLoad one paid skill's complete instructions from a product.No findings
Why it is in this group
- The name "get_full_skill" says "get": a word for reading.
Description, as the server wrote it 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.

list_productsList every product in the Business Suite line with its included skills.No findings
Why it is in this group
- The name "list_products" says "list": a word for reading.
Description, as the server wrote it 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.
Annotations the server declares

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
