DF0049: Connector Call Requires Port and Tool

Message

The devframe_connect_call-tool tool requires { port: number, tool: string }.

Cause

The devframe connect gateway tool devframe_connect_call-tool was invoked without a numeric port or a string tool name — the two fields that identify which instance to dial and which of its tools to call. The error crosses the MCP boundary as structured JSON, so the calling agent can self-correct.

Example

// devframe_connect_call-tool({ tool: 'devframe_state_read' }) → DF0049 (missing port)

Fix

Call devframe_connect_list-instances first — its result carries each instance's port and tool names — then retry with both fields.

Source

• packages/devframe/src/cli/connect.ts — call() throws this when the gateway arguments fail validation.
