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

VerifiedStreamable HTTPWeb executableProductivity & WorkflowKnowledge & Memory

Overview

AI-generated overview

Remote decision-memory service that lets an AI assistant record, search, revisit and resolve consequential decisions across chats and agents.

What you can do
  • Search and recall previously recorded decisions at a decision boundary
  • Create, update and archive decision records with rationale and alternatives
  • Admit and commit decisions, with a human placing the commitment
  • Keep a shared system of record across Claude, ChatGPT, Cursor, Codex and other agents
  • Pair with a companion skill that guides when to recall or capture a decision
When to use it
Useful when you work across several agents or long-running projects and want a fresh assistant to know why earlier choices were made, or when you want consequential forks captured as durable records instead of being lost in chat history.
Requirements
A remote MCP endpoint at decrec.io/mcp over streamable HTTP, with OAuth sign-in required. No packages or environment variables are declared. Some clients install it as a plugin or skill bundle; others need the MCP connector added manually.
Before you install
OAuth grants the server access to your account; it stores account email, organization membership and the decision content you record. Decision records are written to a shared third-party system of record, so avoid recording sensitive material. The README states that agents prepare records but a human commits them.

Installation

In SourceWeft

  1. Open DecRec in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.decrec%2Fdecrec/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

DecRec

AI explores. You decide. DecRec remembers.

Shared decision memory across Claude, ChatGPT, Cursor, Codex, and other agents.

[ChatGPT records DEC-8; Cursor recalls it three weeks later.]

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.

text
Agent  ├─ Skill → judgment: when decisions matter  └─ MCP   → durable decision state               ↕             DecRec
LayerRole
SkillJudgment: what counts as a decision, when to recall, when to capture, when to stop.
MCPDurable state: search, create, update, admit, commit, and archive decisions.
DecRecThe 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
text
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
text
Here is a [Slack thread / meeting notes]. What is worth recording in DecRec? Don't record until I pick.
[paste]
Already picked
text
We picked [option A] over [option B]. Record that decision in DecRec.

  2. URL: decrec-io/decrec-plugin
  3. Sync → select DecRec → Install
  4. Allow when asked.

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: [email protected].

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
