Overview

Description from the maker (original English)

Decision memory for AI agents: record, revisit, and resolve consequential choices.

PopNx MCP’s three pillars

Common questions

Is DecRec safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2026.9.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Your agent forgot. DecRec didn't.

3 weeks ago — ChatGPT

Keep accounts single-user until we validate team demand.

✓ Committed as DEC-8

Today — Cursor, fresh conversation

Before changing the account model: DEC-8 deliberately kept accounts

single-user while validating demand. Want to revisit it?

One decision. Any agent.

How it works

MCP gives the agent access to decisions. The Skill teaches it when those decisions matter.

Agent

├─ Skill → judgment: when decisions matter └─ MCP → durable decision state ↕ DecRec

Layer	Role
Skill	Judgment: what counts as a decision, when to recall, when to capture, when to stop.
MCP	Durable state: search, create, update, admit, commit, and archive decisions.
DecRec	The shared system of record across chats and agents.

Tools without the skill still write; the skill without tools cannot persist across agents.

Why decisions, not everything?

DecRec remembers decisions, not AI output. Agents can prepare and surface records; a human commits the decision.

Your agent already has access to code, chats, docs, and project context. DecRec doesn't try to remember all of it.

It keeps the smaller set of choices that constrain future work:

what you chose
why
what you considered
who committed it
what would justify revisiting it

The goal isn't more context. It's giving a fresh agent the reasoning behind decisions already made.

What the Skill does

Stay in scope — don't advance past what was asked (no catalog → shape → update → explore → admit → commit chain unless requested).

Recall — search only at a decision boundary (consequential choice that constrains later work). Never before ordinary coding.

Capture — offer once when a consequential fork settles; never auto-create; never interrupt trivia.

Humans commit — the agent can prepare and surface records, but it does not place commitments.

Full protocol: skills/decrec/SKILL.md. Exploration prompts: skills/decrec/explore-prompts.md.

Try it

After install, allow the MCP connection, then paste one of these into a new conversation:

Live choice

Should we [option A] or [option B]?

Work through it from more than one side, then record the decision in DecRec.

Or substitute any real decision you're working through.

A thread

Here is a [Slack thread / meeting notes]. What is worth recording in DecRec? Don't record until I pick.

[paste]

Already picked

We picked [option A] over [option B]. Record that decision in DecRec.

What we learned teaching agents when to remember

Useful even if you never use DecRec. Steal these for your own agent skills.

1. Capture only when all three hold

Alternatives (≥2 paths), consequence (constrains later work), future relevance (someone will ask *why*).

2. Don't advance past the ask

Match the stage they requested; stop there.

3. Recall only at a decision boundary

Not before ordinary coding, bugfixes, or implementing an already-chosen approach.

4. Fail-fast and branch on error codes

locked, in_flight, and pin_mismatch mean stop (or reload). Don't infer from the chat and retry.

5. Isolated role passes

Explore from clean contexts; the agent synthesizes options, the agent does not commit.

6. No invented facts

Don't invent stack, vendors, tenancy, or business metrics the brief doesn't state.

See skills/decrec/SKILL.md for the full rules.

Privacy

This plugin connects to the remote MCP server at https://decrec.io/mcp (OAuth). DecRec stores account email, organization membership, and decision content you choose to record. Details: Terms & data policy. Support: hello@decrec.io.
