get_line_chatroom_history_defaultRead recent messages from a specific LINE chat/group and return them as STRUCTURED JSON (array of {sender,time,text,raw}). On macOS this uses foreground screenshot + Apple Vision OCR (this LINE build does NOT expose message text to the Accessibility tree). It briefly brings LINE to the foreground, m…
get_line_chatroom_history_longRead messages from a specific LINE chat/group as STRUCTURED JSON, scrolling up further (more OCR passes) to load older history for summarizing/analyzing a longer period. macOS path: foreground screenshot + Apple Vision OCR; restores your previous frontmost app + cursor when done. Requires an OPEN LI…
get_line_chatroom_history_shortRead only the most recent few messages of a specific LINE chat/group as STRUCTURED JSON, for a quick response. macOS path: a single foreground screenshot + Apple Vision OCR; restores your previous frontmost app + cursor when done. Requires an OPEN LINE main window and Screen Recording permission.
send_message_manualSend a message to a specific LINE chat or group, with pre-send review in LINE. If the user’s intent to auto-send is unclear, use this function by default
send_message_autoSend a message to a specific LINE chat/group and press Enter immediately (no pre-send review). SAFETY GATE: disabled by default; it returns an error unless the environment variable LINE_MCP_ALLOW_AUTO_SEND=true is set. Use only when the user explicitly requests immediate auto-sending.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
5/5 tools missing one or more hints — get_line_chatroom_history_default (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_line_chatroom_history_long (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_line_chatroom_history_short (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
