Overview

AI-generated overview

Lets an assistant run semantic nearest-neighbour search over Nomic Atlas datasets and inspect indices, projections, tags, and organizations.

What it does
A hosted MCP endpoint that exposes read-only tools for Nomic Atlas. It can fetch the current user, an organization, a dataset by id or slug, and find similar records with nearest-neighbour search. It also reports index jobs, projection schemas, and projection tags with their status.
When to use it
Useful when you already keep datasets in Nomic Atlas and want an assistant to look up records, find semantically similar items, or check the state of indices, projections, and tags without leaving the chat.
Requirements
A remote MCP endpoint at no local install. Nomic Atlas credentials are pasted on first connect and stored per user. Network access is required.
Before you install
Nomic Atlas credentials are requested on first connect and stored per user by the service. The free plan allows 100 tool calls per month; paid plans are $9/mo or $90/yr. All listed tools are read-only, so no data is written or deleted.
