Claude Code: ask. ### `loan_payment` - 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 annotation-conflict Description, as the server wrote it: ```untrusted-server-text 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": ""} (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. ``` ## Changes things (3) Creates or changes something that can be changed back. Claude Code: ask. ### `cash_runway` - 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: ```untrusted-server-text 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": ""} (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. ``` ### `target_price` - 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: ```untrusted-server-text 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": ""} (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. ``` ### `unit_economics` - 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: ```untrusted-server-text 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": ""} (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. ``` ## Only reads (4) Looks things up and changes nothing. Claude Code: allow. ### `get_free_skill` - The name "get_free_skill" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load a product's free gateway skill with its complete instructions. FREE. Typical input {"slug": "smb-ops-desk"} returns {"slug": "smb-ops-desk", "skill": "", "instructions": ""}. 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": ""} (for example {"error": "unknown slug ''. Use list_products."}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `get_full_product` - The name "get_full_product" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Load one product in full: its persona plus every paid skill. PREMIUM (license). Typical input {"slug": "smb-ops-desk"} returns {"slug": ..., "name": ..., "persona": "", "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": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `get_full_skill` - The name "get_full_skill" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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": ""}. 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": ""} (for example {"error": "unknown slug ''"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ### `list_products` - The name "list_products" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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": ""}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `business`: ```json { "permissions": { "allow": [ "mcp__business__list_products", "mcp__business__get_free_skill", "mcp__business__get_full_product", "mcp__business__get_full_skill" ], "ask": [ "mcp__business__unit_economics", "mcp__business__loan_payment", "mcp__business__cash_runway", "mcp__business__target_price" ], "deny": [] } } ```
