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.
npx agentmods add rules/commercetools/mcp-essentials/docsgit clone --depth 1 https://github.com/commercetools/mcp-essentialsWhat it costs to keep this loaded
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 | $0.00004 | $0.00322 |
| Opus 5 | $0.00002 | $0.00161 |
| Sonnet 5 | $0.00001 | $0.00064 |
| Haiku 4.5 | $0.00000 | $0.00032 |
Grade A, and why
docs 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 yesterday.
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
Creating a New namespace tool Function in @commercetools/agent-essentials
Updating the README.md file in the project root with the newly added feature or namespaces
This document outlines the steps taken to implement an updated README.md file by connecting to the official commercetools API.
The following steps are defining implementation of an example products.create. So the (namespace) here refers to product.
Implementation Steps
- Gather info regarding the (namespace)
- Search commercetools docs at https://docs.commercetools.com/api and find the (namespace)
- In this example
https://docs.commercetools.com/api/projects/products
- Define Available Tools
In the
### Special Tool Optionssection of theAvailable Toolsadd to the end of the table the newly created or provided namespaces- Using the namespace fetched in previous step and complete the table like the example provided below using the product namespace
| products.read | Read product information |
| products.create | Create product information |
| products.update | Update product information |
- After updating the Available Tools table, ensure all the original formatting is maintained and do not add or carryout any other special editing or formatting.
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.

docs is a cursor rule published in the GitHub repository commercetools/mcp-essentials (13 stars, last pushed 15d ago), licensed MIT. It adds 4 tokens to every session and 322 once invoked, about $0.0000 per session on Opus 5. 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.
