The Stateless MCP Skill File Every CTO Should Use

Most agent stacks fail because the server remembers too much. Stateless MCP fixes that by keeping context, risk, and review rules in the client where the team can see them.

If you run engineering, product, support, or ops, hidden memory is the part that burns you. The model drafts a good answer. The server keeps some history. A teammate picks up the task later and nobody knows what the agent saw, changed, or skipped.

That breaks trust. It also makes debugging miserable. Teams spend hours asking whether the model was wrong or the workflow was wrong.

Most leaders focus on model choice. That is the wrong fight. The real decision is where state lives and who owns the handoff.

Why hidden state breaks teams

1. Support gets one answer, product gets another, engineering gets a third.
2. The same workflow handles read tasks and ship tasks.
3. Audits depend on chat history, which is a bad database.

When the state lives inside a random server session, you cannot recreate the path. That hurts overseas teams first because they already work across time zones. A small context gap in Austin becomes a lost hour in Manila or Warsaw.

The right fix is not more prompt polish. It is a control plane that keeps the important choices outside the model.

The stateless MCP rule set

1. Keep context in the client

Store the task brief, source docs, and risk class outside the agent. Pass them in as explicit inputs every time.

2. Separate read, draft, change, and ship

Read tasks can move fast. Draft tasks can move fast with review. Change tasks need a diff or draft check. Ship tasks need a human gate before anything leaves the system.

3. Add a re-entry point

Every workflow needs a place where a person comes back in.

For engineering, that can be the diff review. For support, that can be the final reply before send. For ops, that can be the incident note before it goes out.

4. Log the run

Record the model, the source docs, the reviewer, and the outcome. If a workflow matters and nobody can reconstruct it, the workflow is too loose.

The skill file

# stateless-mcp-control-plane.skill.md

## Mission
Let agents draft fast while humans own the risky steps.

## State rules
- Store task context in the client
- Pass inputs explicitly
- Never rely on hidden server memory for approvals

## Routing
- Read: summarize, classify, compare
- Draft: replies, specs, runbooks
- Change: docs, tickets, code, deploy prep
- Ship: merge, send, publish, deploy

## Review gates
- Change requires a diff or draft review
- Ship requires a human approve step
- Support replies need a send review
- Ops notes need a final check

## Logging
Record:
- task
- model
- source docs
- reviewer
- outcome

That file is small on purpose. Small files get used. Long policies get ignored.

A real CTO example

At one company, the engineering team had solid people and messy handoffs. Support used one assistant. Product used another. Engineering used a third. Every team thought it was saving time. Every team was rebuilding context.

We moved the shared rules into one control plane. The result was not magic. It was cleaner escalations, fewer "what did the agent see?" questions, and faster debugging when a handoff broke.

That same pattern works outside engineering. Support can draft replies with the same rules. Product can clean specs. Ops can prep incident notes. Once the workflow is explicit, AI helps the whole company instead of one team.

What to copy this week

• Create one skill file for task routing
• Define the four task classes
• Put review gates before any state change
• Log every meaningful run

The CTO job here is not chasing a smarter model. It is building a workflow that stays readable when humans and agents both touch the same work.
