Overview

AI-generated overview

Lets an assistant log decisions with their expectations, attach supporting evidence, and track metrics in a ZeroWidth Ledger workspace.

What it does
The server connects an assistant to ZeroWidth Ledger, a workspace for recording decisions. According to the registry description, it can log decisions together with the expectations attached to them, add evidence to those records, and track metrics. No individual tools are listed in the manifest, so the exact operations available are not documented here.
When to use it
Worth adding when a team wants an assistant to capture decisions and their expected outcomes as they happen, and to keep supporting evidence and metrics alongside them. Less useful if you only need general note-taking or task management, since the described scope is decision and metric tracking in Ledger.
Requirements
A remote streamable HTTP endpoint at nothing is installed locally. An Authorization header is required, containing a bearer token described as a workspace API key or personal access token obtained from accounts.zerowidth.ai. Network access to the endpoint is needed. No environment variables or packages are declared.
Before you install
The connection requires an Authorization header carrying a bearer token, described as a workspace API key or personal access token from accounts.zerowidth.ai. Treat that token as a secret: anyone holding it can act as the workspace through this server. Because the server records decisions, evidence, and metrics, assume the content you send is stored in the workspace and visible to others with access. No tool list is published, so confirm what it can write or change before use.
