What Mistral AI (BYOK) is for

Mistral AI (BYOK) lets an AI assistant read your own Mistral AI data through the Mistral AI API with a key you supply (API key). Read-only: 8 tools (list_models, list_files, list_batch_jobs, list_fine_tuning_jobs, list_agents, list_libraries, list_library_documents, list_conversations). 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.mistral.ai. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Mistral AI. Mistral AI 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 Mistral models can I use and which are deprecated?"
• "What files have I uploaded to Mistral for fine-tuning or batch?"
• "Did my Mistral batch job finish and how many requests failed?"
• "Which of my Mistral fine-tuning jobs have finished?"
• "Which Mistral agents have I created?"
• "Which Mistral document libraries do I have and how big are they?"

What it does

• list_models: List Mistral models available to the key with context length, capabilities, aliases and deprecation info.
• list_files: List files uploaded to your Mistral account with name, size, purpose and creation time.
• list_batch_jobs: List your Mistral batch jobs with model, endpoint, status and request counts (total, succeeded, failed).
• list_fine_tuning_jobs: List your Mistral fine-tuning jobs with base model, resulting model, status, trained tokens and dates.
• list_agents: List the Mistral agents in your workspace with name, description, model, version and update time.
• list_libraries: List the document libraries you can access in Mistral, with name, document count, total size and owner type.
• list_library_documents: List documents in one Mistral library with name, size, page count and processing status.
• list_conversations: List your Mistral conversations (agent API) with name, model and timestamps; message content is not returned.

BYOK key

You bring your own Mistral AI API key (https://console.mistral.ai/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.mistral.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.

Mistral AI (BYOK) — Privacy Policy

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

What Mistral AI (BYOK) is. Mistral AI (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Mistral AI data: Read your Mistral AI models, files, batch jobs, fine-tuning jobs, agents and document libraries with BYOK. You bring your own Mistral AI API key; the assistant sends it to us with each request.

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

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

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

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