comfyui-mcp/dist/services/workflow-target-store.js

Local-first, agent-native control plane for ComfyUI — MCP server + autonomous sidebar agent that drives your live graph in natural language on ANY LLM: Claude/ChatGPT/Gemini on your subscription (no API key), free local models via Ollama (fully offline),

// Per-panel-tab workflow target: which open ComfyUI workflow tab the agent
// should edit. Without pinning, graph_* commands hit whatever workflow the user
// is currently viewing — browsing another tab mid-conversation redirects edits.
//
// Pinning injects `workflow_path` on workflow-scoped bridge commands. The panel can
// only read/edit the workflow currently IN VIEW (its graph executors run against the
// active canvas and fail closed on a workflow_path mismatch — panel #349/#186), so a
// pin must target the active canvas at pin time (enforced in panel_set_workflow_target)
// and the injected `workflow_path` acts as a GUARD: if the user later switches away, the
// next graph command fails loudly instead of silently editing the wrong graph. It does
// NOT enable background editing of a non-active tab.
