Authentication and access¶
Connect your assistant to https://mcp.thecoindaily.co/mcp using its remote-MCP OAuth flow. Sign in with the same verified email used for your Coin Daily subscription. Do not paste a password, payment details or access token into chat.
Research and the MCP share access to the existing Research & AI subscription. Authentication identifies you; a current entitlement check determines whether the paid tools can be used. An old “Pro” label in a token or key is not sufficient by itself.
| Result | Meaning |
|---|---|
| 401 | Sign-in is absent or invalid; reconnect through the host |
| 402 | Signed in, but this account has no current product access |
| 503 | Access could not be checked; retry rather than purchasing again |
The public website, product information and these docs remain readable without a subscription. Sign in, link Google and manage your account covers the customer sign-in methods; Manage your subscription covers billing, eligible trials and cancellation.
Custom clients¶
Use standard MCP discovery and OAuth metadata from the server. Token scopes, resource audience and registered redirect URIs must match the connection; do not work around an OAuth error by weakening those checks.
Previously issued API keys remain a supported credential where configured, but still require current product access. There is no need for browser/assistant users to create or expose a key.
The MCP authenticates the request, then uses a short-lived signed service assertion to call the Research API. It does not forward the user's bearer credential to data sources.
