What HubSpot CRM Schema (BYOK) is for

HubSpot CRM Schema (BYOK) lets an AI assistant read your own HubSpot CRM Schema data through the HubSpot CRM Schema API with a key you supply (HubSpot private app access token (scopes: crm.schemas.*.read, tickets for ticket pipelines)). Read-only: 9 tools (list_properties, get_property, list_property_groups, list_pipelines, get_pipeline, list_pipeline_stages, list_custom_object_schemas, get_custom_object_schema, list_association_labels). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.hubapi.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by HubSpot CRM Schema. HubSpot CRM Schema and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "What properties does the deal object have in HubSpot?"
• "What are the allowed values of the dealstage property?"
• "How are the company properties grouped in HubSpot?"
• "What are our HubSpot deal pipelines and stages?"
• "What stages does the default HubSpot deal pipeline have?"
• "List the stages of the default deal pipeline in order"

What it does

• list_properties: List the properties (fields) defined for a CRM object type with name, label, type, field type, group and description. Enumeration options are left out here.
• get_property: Get one property definition of a CRM object type, including its dropdown options (label and value) for enumerations.
• list_property_groups: List the property groups of a CRM object type with internal name, label and display order.
• list_pipelines: List the pipelines of an object type (deals or tickets) with label and all stages including stage metadata such as closed state and win probability.
• get_pipeline: Get one pipeline with its label and stages (id, label, order, metadata).
• list_pipeline_stages: List the stages of one pipeline with stage id, label, display order and metadata (closed state, probability).
• list_custom_object_schemas: List the account's custom object schemas with object type id, name, labels, primary display property and dates. Property lists are left out.
• get_custom_object_schema: Get one custom object schema: labels, required and searchable properties, primary display property and its association definitions.
• list_association_labels: List association types and custom labels that can link one object type to another (for example deals to companies), with type id and category.

BYOK key

You bring your own HubSpot CRM Schema HubSpot private app access token (scopes: crm.schemas.*.read, tickets for ticket pipelines) (https://developers.hubspot.com/docs/apps/legacy-apps/private-apps/overview). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.hubapi.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What HubSpot CRM Schema (BYOK) is. HubSpot CRM Schema (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own HubSpot CRM Schema data: Read your HubSpot CRM configuration: properties and groups, deal and ticket pipelines with stages, custom object schemas and association labels using your own private app access token. You bring your own HubSpot CRM Schema HubSpot private app access token (scopes: crm.schemas.*.read, tickets for ticket pipelines); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one HubSpot CRM Schema call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.hubapi.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If HubSpot CRM Schema rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What HubSpot CRM Schema receives. The request we make on your behalf, including the key and the arguments, under HubSpot CRM Schema's own terms and privacy policy. HubSpot CRM Schema acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer HubSpot CRM Schema gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your HubSpot CRM Schema data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. HubSpot CRM Schema (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at HubSpot CRM Schema at any time to end all access.

Children. HubSpot CRM Schema (BYOK) is a general-audience service operated by the adult using the assistant, under HubSpot CRM Schema's own age rules.
