Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00459 |
| Opus 5 | $0.00000 | $0.00230 |
| Sonnet 5 | $0.00000 | $0.00092 |
| Haiku 4.5 | $0.00000 | $0.00046 |
Grade A, and why
namespace-scopes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says
Splitting Namespace Functions into Scopes
This rule defines how to organize functionality in a namespace by scope.
Structure
-
Split functionality into three scopes:
customer- Functions related to customer operationsstore- Functions related to store operationsadmin- Functions related to admin operations
-
Create separate files for each scope:
customer.functions.ts- Customer-related functionsstore.functions.ts- Store-related functionsadmin.functions.ts- Admin-related functions
-
Create a main functions file (e.g.,
functions.ts) that:- Imports all scope files
- Exports a context mapping function (
contextTo<namespace>FunctionMapping)
Implementation Rules
- No cross-imports: Do not import between scope files (customer/store/admin)
- Context mapping: Create a mapping function that determines which function to use based on context parameters
- Exports: Export all functions through the main functions file
Example (Order namespace)
In functions.ts:
import * as customer from './customer.functions';
import * as admin from './admin.functions';
import * as store from './store.functions';
export const contextToOrderFunctionMapping = ({
customerId,
storeKey,
}: {
customerId?: string;
storeKey?: string;
}): Record<string, Function> => {
if (customerId) {
return {
read_order: customer.readCustomerOrder,
};
}
if (storeKey) {
return {
read_order: store.readStoreOrder,
create_order_from_cart: store.createOrderFromCartInStore,
create_order_from_quote: store.createOrderFromQuoteInStore,
update_order: store.updateOrderByIdInStore,
};
}
return {
read_order: admin.readOrder,
create_order_from_cart: admin.createOrderFromCart,
create_order_from_quote: admin.createOrderFromQuote,
create_order_by_import: admin.createOrderByImport,
update_order: admin.updateOrder,
};
};
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

namespace-scopes is a cursor rule published in the GitHub repository commercetools/mcp-essentials (13 stars, last pushed 15d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 459 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
