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%2Fknack/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。把它添加到你客户端的 mcpServers 配置中。

}Connect Claude, Cursor, or any MCP client to your Knack no-code database — read, create, update and delete records, and inspect objects, fields and schema.
Live endpoint: https://knack.usefulapi.io/mcp · Homepage: https://usefulapi.io/knack
https://knack.usefulapi.io/mcp.claude mcp add --transport http knack https://knack.usefulapi.io/mcp, then run /mcp to log in.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 Knack credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/knack/
On first connect you'll paste two credentials — your Application ID and REST API Key (Knack Builder → Settings → API & Code). They're sent as the X-Knack-Application-Id and X-Knack-REST-API-Key headers on every request.
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.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with knack_upgrade (it returns a Stripe Checkout link). Cancel any time with knack_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running knack_upgrade before then undoes the cancel. Or write to [email protected].

Get application schema
Fetch a Knack application's full schema/metadata — its objects (tables), fields, and scenes. Knack API: GET /applications/{app_id}. Returns the raw JSON as-is. app_id defaults to the configured KNACK_APPLICATION_ID.
appIdList objects (tables)
List an application's objects (tables) as a compact array [{ key, name, fieldCount }]. Convenience over GET /applications/{app_id}. app_id defaults to the configured KNACK_APPLICATION_ID.
appIdList fields for an object
List the fields of ONE object as [{ key, name, type, required }]. Fetches GET /applications/{app_id} and returns the fields of the object whose key === objectKey (e.g. "object_1"). app_id defaults to the configured KNACK_APPLICATION_ID.
appIdobjectKey必填List records
List an object's records. Knack API: GET /objects/{object_key}/records. Returns the paged envelope { total_pages, current_page, total_records, records: [...] } as-is. Records carry both field_x (formatted) and field_x_raw (structured) values. Page with page / rows_per_page (max 1000), sort with sort_field / sort_order, and filter with the `filters` object.
pagefiltersobjectKey必填sort_fieldsort_orderrows_per_pageGet a record
Fetch a single record by id. Knack API: GET /objects/{object_key}/records/{record_id}. Returns the bare record (with both field_x and field_x_raw values).
recordId必填objectKey必填Raw Knack API GET
Power-user escape hatch: GET any Knack API path not wrapped by a dedicated tool (e.g. view-based reads). READ-ONLY — only GET is allowed. Path starts with a slash (e.g. "/objects/object_1/records"). Knack API: GET {path}.
path必填queryCreate a record
MUTATES Knack data — creates a new record in an object. Knack API: POST /objects/{object_key}/records. Provide `fields` as an object keyed by field key, e.g. { "field_1": "Acme", "field_2": 100 }. Auto Increment / Formula / Equation fields are read-only and cannot be set. Returns the created record.
fields必填objectKey必填Update a record
MUTATES Knack data — updates a record. Knack API: PUT /objects/{object_key}/records/{record_id}. Provide `fields` as an object keyed by field key; only the included fields change, e.g. { "field_1": "Acme Inc" }. Auto Increment / Formula / Equation fields are read-only. Returns the updated record.
fields必填recordId必填objectKey必填Delete a record
MUTATES Knack data — permanently DELETES a record (irreversible). Knack API: DELETE /objects/{object_key}/records/{record_id}. Knack returns { delete: true } on success.
