What Mixpanel Lexicon (BYOK) is for

Mixpanel Lexicon (BYOK) lets an AI assistant read your own Mixpanel Lexicon data through the Mixpanel Lexicon API with a key you supply (service account username). Read-only: 8 tools (list_schemas, list_schemas_for_entity, get_schema, list_annotations, get_annotation, list_annotation_tags, list_warehouse_imports, get_warehouse_import). 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 mixpanel.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Mixpanel Lexicon. Mixpanel Lexicon 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:

• "Which events have a documented schema in my Mixpanel Lexicon?"
• "Show the Lexicon schema for the Added To Cart event in Mixpanel"
• "What properties does the Added To Cart event have in Mixpanel Lexicon?"
• "What annotations are on my Mixpanel charts this quarter?"
• "Show Mixpanel annotation 11"
• "Which annotation tags exist in Mixpanel?"

What it does

• list_schemas: List every Lexicon schema in the project: entity type (event or profile), name and description. Only entities that have a schema are included.
• list_schemas_for_entity: List the Lexicon schemas of one entity type, optionally narrowed to one entity name.
• get_schema: Get the schema of one entity: description and the property definitions (type and description of each property).
• list_annotations: List chart annotations of the project (date, text, tags and creator name), optionally between two dates.
• get_annotation: Get one chart annotation by id: date, text, tags and creator name.
• list_annotation_tags: List the annotation tags that are attached to at least one annotation, with a flag whether each is in use.
• list_warehouse_imports: List warehouse imports configured for the project: import type, sync mode, schedule, paused flag and last dispatch time (no creator details).
• get_warehouse_import: Get one warehouse import with its table, column and property mappings and sync settings.

BYOK key

You bring your own Mixpanel Lexicon service account username (https://docs.mixpanel.com/reference/service-accounts). 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 mixpanel.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.

Data sources

What it is not

Mixpanel Lexicon (BYOK) — Privacy Policy

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

What Mixpanel Lexicon (BYOK) is. Mixpanel Lexicon (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Mixpanel Lexicon data: Read your Mixpanel Lexicon schemas (data dictionary), chart annotations and warehouse imports with your own service account (US data residency). You bring your own Mixpanel Lexicon service account username; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Mixpanel Lexicon 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 mixpanel.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 Mixpanel Lexicon 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 Mixpanel Lexicon receives. The request we make on your behalf, including the key and the arguments, under Mixpanel Lexicon's own terms and privacy policy. Mixpanel Lexicon acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Mixpanel Lexicon 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 Mixpanel Lexicon 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. Mixpanel Lexicon (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 Mixpanel Lexicon at any time to end all access.

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

Changes. We will post changes here with a new effective date.
