MCP terminal access
Expose 3270 and 5250 terminal sessions to MCP clients so agents can read screens, execute mapped keys, and maintain stable host context.
MCP terminal access lets authorized MCP clients connect to OL Terminal, sign in to a host through configured login macros, read the current terminal screen, and execute terminal actions using the server's configured key mappings.
The MCP screen model includes host field structure and presentation attributes such as color, background, underline, bright text, and hidden-field handling. OL Terminal keeps a stable terminal context for a signed-in user across MCP connections for the same tenant, connection, and login macro, waits for host screens to settle after actions, and releases terminals when the user disconnects or the session expires.
