Overview

AI-generated overview

Lets an assistant search, write and run work across the ZeroWidth workspace products Compass, Workbench, Caliper, Ledger, Prism and Napkin.

What it does
ZeroWidth exposes a remote MCP endpoint that connects an assistant to the ZeroWidth workspace suite. According to the registry description, it lets the assistant search, write and run work across Compass, Workbench, Caliper, Ledger, Prism and Napkin. The manifest does not list individual tools, so the exact operations available are not documented here.
When to use it
Worth adding when you already work in the ZeroWidth suite and want an assistant to search across those products or carry out work in them from a chat client. Less useful if you do not use ZeroWidth, since the server only acts on that workspace.
Requirements
A remote MCP endpoint at over streamable HTTP. No local package or runtime is needed. Authentication uses an Authorization header 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 required.
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: it likely grants access to workspace content, and the description says the assistant can write and run work, so actions may create or change data. No tool list is published, so review what the server can actually do before granting a token.
