Agent Plugin

MCP and Skill for the agents you already use.

The Agent Plugin is a Skill plus the DecRec MCP server. The Skill teaches the agent when a decision matters. MCP is how it reads and writes the shared record.

Tools without the Skill still write. The Skill without tools cannot persist across agents.

MCP

Add this URL as a remote MCP server / custom connector. Do not put a token in the URL.

https://decrec.io/mcp

Opening that URL in a browser is not this page. /mcp is the protocol endpoint (OAuth clients probe it). This page is the human docs.

Auth

OAuth — most clients (Claude, ChatGPT, Cursor, Codex, VS Code). Add the MCP URL; sign in on DecRec and Allow.
Access token — Settings → Access tokens. Some HTTP clients send Authorization: Bearer drec_…. Revoke OAuth grants or tokens there without changing the MCP URL.

Install

Create a DecRec account first, then install the plugin in your client. Per-client detail also lives in the plugin README.

Cursor

Slash command in the chat input — not a message to the agent.

/add-plugin decrec@https://github.com/decrec-io/decrec-plugin

Claude Code

/plugin marketplace add decrec-io/decrec-plugin
/plugin install decrec@decrec

Codex CLI

codex plugin marketplace add decrec-io/decrec-plugin
codex plugin add decrec@decrec

Claude (Web and Desktop)

Customize → Plugins → Add → Add marketplace. Paste this, Sync, then install DecRec.

ChatGPT

Desktop Work

Marketplace plugin. Does not run in Chat. Add marketplace, install decrec, then start a new Work conversation.

decrec-io/decrec-plugin

Web and Desktop Chat

Marketplace plugin does not run here. Add the MCP URL as a connector, then upload the skill ZIP under Plugins → Skills. Start a new conversation after you connect.

https://decrec.io/mcp

Download the skill ZIP

VS Code

Command Palette, then paste the GitHub URL.

Tools

Agents get argument shapes from the server. This is the catalog, not a request/response reference.

get_decision
Load the current brief, pins, and recommendation.
list_decisions
Browse active DEC-n newest-first.
search_decisions
Semantic search by topic — not a recency list.
create_decision
Admit a new decision. You become the owner.
update_decision
Write a new brief version on an existing decision.
admit_exploration
Attach exploration to the current approved tip.
commit_decision
Owner commits the current recommendation.
decline_decision
Owner declines. No commitment is stored.
archive_decision
Owner archives and locks the decision.
list_councils
List org exploration councils (labels only).
get_council
Load a council including role focus (omit ref → default).
whoami
Email and org for this connection.

When to search, capture, or stop is in the Skill. That is the protocol — not this page. Why MCP wasn't enough.
