mcp open tool returns success but tab does not appear in UI

[hartsock]

Bug

mcp__scrybe__open returns a valid DocumentId but the tab does not appear in the Scrybe UI. The file is not opened.

Repro

mcp__scrybe__open(path="/path/to/file.md")
# Returns: {"id": "DocumentId(...)", "path": "..."}
# Expected: new tab appears in Scrybe
# Actual: no tab, UI unchanged

Opened 4 files in parallel via MCP — all returned success, none appeared. Subsequent mcp__scrybe__state call confirmed only the original 2 tabs were open.

Workaround

Use the CLI directly:

~/venv/bin/scrybe /path/to/file.md

CLI reliably opens the tab. MCP does not.

Environment

• Scrybe MCP server via scrybe-mcp-server stdio
• macOS, single-instance app
