New MTContext users often look for a license code in their welcome email — there isn't one. Activation works a little differently, and it's simple once you know the shape of it: you generate a terminal key in your dashboard and bind it to your terminal by connecting once. This article walks through it.
What a terminal key is
A terminal key is the single credential your Expert Advisor and your AI client both use. It looks like MTMCP- followed by 32 hex characters, and each key is bound to exactly one MetaTrader 5 terminal the first time that terminal connects with it. That one-key-one-terminal binding is what guarantees a command can never be routed to the wrong account.
Step 1 — Generate the key
-
Log in to your dashboard with the email you used at checkout.
-
Go to Terminal Keys → Generate New Key.
-
Copy the key somewhere safe — the plaintext value is shown only once. If you lose it, you generate a new one; the old plaintext can't be revealed again.

Step 2 — Bind it to your terminal
A freshly generated key isn't usable until a terminal has connected with it once:
-
Install the MTContext Expert Advisor on the terminal you want to connect (see Installing the EA on MT5).
-
Enter the terminal key as the EA's license input and let it connect once.
-
When the EA shows as connected in your dashboard, the key is bound. It will now work in any MCP client configuration.
Step 3 — Use it in your AI client
With the key bound, add it to your AI client as the bearer token (Authorization: Bearer MTMCP-YOUR-TERMINAL-KEY) pointing at https://mcp.mtcontext.com/mcp/v1. The client guides — Connecting Claude Desktop and the others — show exactly where each client wants it.
Does the free tier get a key?
Yes. Every account, including free, generates a terminal key the same way — the tier just determines which tools the key can use (free keys are read-only).
If activation isn't working
-
Confirm the key starts with
MTMCP-and has no trailing spaces. -
Confirm the EA has connected at least once so the key is bound.
-
A
401 Unauthorizedmeans the key is invalid, mistyped, or revoked; a403 Forbiddenmeans it's valid but your tier lacks that tool's capability.
