Find your key at: app.goagentcy.com → Settings → API KeysFeature is still in BETA as of April 2026 (Mistral’s own label, last confirmed Feb 17 2026 — not yet GA). Available on all plans including Free — the only major browser AI client with free-tier MCP support. AUTH FLOW: Mistral auto-detects the auth method from your server’s MCP metadata (HTTP Bearer / OAuth 2.1 / None). Because Agentcy uses HTTP Bearer, you’ll see a Bearer token field — NOT an OAuth screen. Other MCP servers may show different prompts (e.g., Metricool uses OAuth 2.1). Account owners on Free/Pro/Student plans are Admin by default; Team/Enterprise admins manage member access. CURRENT LIMITATIONS (Mistral docs, Feb 2026): Dynamic Tool Discovery, Resources, and Automatic Prompt Templates are NOT yet supported.
Stuck or want to verify these instructions yourself? These are the documentation sources we used. If something here doesn't match what you see in your client, the vendor may have updated their UI — and we'll get this page updated.
