Keystone Coach
Deployed June 2026A remote MCP server that brings a sales-coaching method into Claude.
- Built by
Kimjamae built and operates the server and manages its seat licenses. The coaching method comes from Keystone, a Korean sales-education and field-coaching consultancy, and the licenses go to the dealership salespeople Keystone coaches.
- What it does
A salesperson describes a customer conversation: the situation, and optionally the stage and why the customer is hesitating. Keystone Coach returns the next step, a strategy for the objection, the questions to ask before drafting a message, and a follow-up plan: a message on day 0, one follow-up on day 2 if there is no reply, and a status check on day 5.
- How it is delivered
Each salesperson receives a personal download link tied to a seat license key, opens the package in Claude Code, and approves the connection. A one-line command is also available.
Seats are managed from an admin dashboard: issue, suspend, or reclaim a key and set the seat limit, without redeploying.

SOP-Sync
PrototypeWhen a company procedure changes, the training changes with it once a person approves.
- Overview
SOP-Sync keeps training current: it compares the old and new versions of a procedure, regenerates only the affected modules and quiz questions, and sends the draft to an approval queue.
- Build
Turns a procedure document into short modules and quizzes. Every module is linked to the source paragraphs it came from.
- Sync
Compares two versions of the document and regenerates only the modules that the change affects.
- Review
A separate reviewer agent checks the draft against the source for distortion and omission.
- Approve
A person reviews the change summary and publishes the new version. Agents never publish.
- Current stage
A working prototype built as Claude Code subagents. On a sample refund-process procedure revised from version 1 to version 2, it built the course, regenerated only the affected modules, and produced the approval request for a person to review. The reviewer step is defined but has not yet been run on this example. Our target users are small and mid-sized companies in Korea.
