概览

AI 生成的概览

托管的 Nomic Atlas 连接器，让助手浏览 Atlas 数据集并基于其嵌入向量做语义近邻检索。

可以做什么
  • 查询当前账号及其可访问的组织，并列出组织下的数据集
  • 按 ID 或按组织与数据集 slug 获取数据集，包括其结构、规模、索引与投影
  • 在嵌入空间中找出与指定记录最相似的记录，并返回距离
  • 查看索引构建任务状态与某个投影的字段结构
  • 列出投影上的标签，并检查标签成员是否已计算完成
  • 查看本月调用量、提交缺失功能请求，以及管理付费订阅
适用场景
当你的数据已经存放在 Nomic Atlas 中，希望助手帮你探索数据、查看数据集结构，或回答“哪些记录与某条记录相似”这类问题时适用。它只读取 Atlas，适合探索与相似度查询，而不是创建或修改数据集。
运行要求
远程 streamable HTTP 端点，无需本地安装。只需填入服务器地址，随后通过 OAuth 使用 Nomic Atlas 账号登录，凭据经校验后按用户存储。客户端配置中不要放 API key 或 Authorization 头。免费方案每月 50 次工具调用。
安装前请注意
OAuth 登录时需把 Nomic Atlas 凭据交给托管服务，因此需信任运营方。付费方案通过升级工具返回的 Stripe Checkout 链接付款，从 Pro 升级到 Pro+ 会立即补收差价；取消后当期不退款。这些管理工具会变更订阅，让助手执行前应先确认。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Nomic Atlas MCP by usefulapi，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.usefulapi%2Fnomic-atlas/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

README

Nomic Atlas MCP by usefulapi

Semantic nearest-neighbour search over your datasets, plus indices and projections. Hosted, no local install.

Live endpoint: https://nomic-atlas.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://nomic-atlas.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http nomic-atlas https://nomic-atlas.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "nomic-atlas": {      "url": "https://nomic-atlas.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Nomic Atlas credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/nomic-atlas/

On first connect you'll paste your Nomic Atlas credentials. They are validated, stored per-user, and scoped to you — no keys in config files.

Tools

nomic_get_organizationreadGet an organisation
nomic_get_datasetreadGet a dataset by id
nomic_get_dataset_by_slugreadGet a dataset by name
nomic_nearest_neighbors_by_idreadFind similar records

nomic_atlas_request_featuremetaRequest a missing feature
nomic_atlas_upgrademetaUpgrade to Pro or Pro+
nomic_atlas_cancel_subscriptionmetaCancel the Pro subscription

read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.

Pricing

PlanPriceLimit
Free$050 tool calls / month
Pro$9/mo or $90/yr (2 months free)10,000 tool calls / month
Pro+$39/mo or $390/yr (2 months free)100,000 tool calls / month

Each paid plan covers this server only. Ask your AI to run nomic_atlas_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with nomic_atlas_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with nomic_atlas_upgrade before then undoes the cancel. Or write to [email protected].

工具

9

nomic_get_user

Get the current user

Fetch the account the API key belongs to, including the organisations it can access. Start here — the organisation slug feeds the other tools. Atlas: GET /v1/user.

无需输入参数。

nomic_get_organization

Get an organisation

Fetch an organisation by slug, with the datasets it holds. Atlas: GET /v1/organization/{slug}.

输入参数slug必填

nomic_get_dataset

Get a dataset by id

Fetch a dataset (Atlas calls it a project) by id — its schema, size, indices and projections. Atlas: GET /v1/project/{id}.

输入参数dataset_id必填

nomic_get_dataset_by_slug

Get a dataset by name

Fetch a dataset by organisation slug and dataset slug — the human-readable path, and usually easier than finding the UUID. Atlas: GET /v1/project/{organization_slug}/{project_slug}.

输入参数dataset_slug必填organization_slug必填

nomic_nearest_neighbors_by_id

Find similar records

Semantic search: given the ids of records already in a dataset, return their nearest neighbours in embedding space, with distances. This is what Atlas is for — finding what resembles what across unstructured data. Needs a BUILT index; if the map is still building the call fails with a 500, so check nomic_get_index_job. Atlas: POST /v1/project/data/get/nearest_neighbors/by_id.

输入参数k必填datum_ids必填atlas_index_id必填

nomic_get_index_job

Get an index job

Fetch the status of an index-building job. Atlas indexes take time to build, and a vector search against an unbuilt map fails — this is how you tell which it is. Atlas: GET /v1/project/index/job/{job_id}.

输入参数job_id必填

nomic_get_projection_schema

Get a projection's schema

Fetch the field schema of one projection — the columns available on its records. Atlas: GET /v1/project/projection/{projection_id}/schema.

输入参数projection_id必填

nomic_list_tags

List a projection's tags

List the tags defined on one projection — the labelled selections a person made on the map. Atlas: GET /v1/project/projection/tags/get/all.

输入参数dataset_id必填projection_id必填

nomic_get_tag_status

Get a tag's status

Check whether a tag has finished computing its membership. A tag that is still building returns partial results. Atlas: GET /v1/project/projection/tags/status.

输入参数tag_id必填dataset_id必填
