What Helicone (BYOK) is for

Helicone (BYOK) lets an AI assistant read your own Helicone data through the Helicone API with a key you supply (API key). Read-only: 8 tools (query_requests, count_requests, query_users, query_sessions, list_properties, list_prompts, count_prompts, list_webhooks). 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.helicone.ai. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Helicone. Helicone 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 were my most recent LLM requests in Helicone and what did they cost?"
• "How many LLM requests has Helicone logged in total?"
• "Which users cost me the most in Helicone this week?"
• "Show my Helicone sessions from the last day"
• "Which custom properties do I track in Helicone?"
• "Which prompts are saved in Helicone?"

What it does

• query_requests: List logged LLM requests, newest first, with model, provider, status, token counts, cost in USD, latency, user and custom properties (prompt and response bodies are left out).
• count_requests: Count all logged LLM requests in the Helicone account.
• query_users: List the end users that made requests in a time window with request count, prompt and completion tokens and cost.
• query_sessions: List sessions (grouped traces) in a time window with name, request count, tokens, cost and average latency.
• list_properties: List the custom property names attached to requests (for example Environment or Feature).
• list_prompts: List saved prompts with name, tags and creation time, one page at a time.
• count_prompts: Count the saved prompts.
• list_webhooks: List configured webhooks with destination, version and creation time (the signing key is not returned).

BYOK key

You bring your own Helicone API key (https://us.helicone.ai/settings/api-keys). 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.helicone.ai 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.

Notices

Reads logs and analytics only (queries are sent as POST bodies but change nothing). Request and response bodies are not returned. EU-region accounts use a different Helicone host that this connector does not call.

Data sources

• https://docs.helicone.ai/rest/request/post-v1requestquery (the API this connector calls, with a BYOK key)

Live from the Helicone API (api.helicone.ai) with a BYOK key; documentation: https://docs.helicone.ai/rest/request/post-v1requestquery. Endpoints checked against that documentation on 2026-10-16.

What it is not

Helicone (BYOK) — Privacy Policy

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

What Helicone (BYOK) is. Helicone (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Helicone data: Read your Helicone LLM request logs, sessions, users, properties, prompts and webhooks with your own API key. You bring your own Helicone API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Helicone 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.helicone.ai, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Helicone 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 Helicone receives. The request we make on your behalf, including the key and the arguments, under Helicone's own terms and privacy policy. Helicone acts at your direction and is the only recipient of the data of your request besides our hosting provider.

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

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

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