Category & Scope

Tools & Capabilities Breakdown

Acheron MCP Server Tools (6)

bridge_save_context

Remember something for later. Use this when the user says things like "remember this", "save this", "note this", "keep this for later", "don't forget", or when an important decision, preference, or insight comes up that should persist across conversations. This saves context that will be available in ALL Claude surfaces (Chat, Code, Cowork) — even in future sessions. Use proactively when you recognize something worth remembering: a decision made, a user preference expressed, a lesson learned, a key file identified, or a workflow established.

bridge_get_context

Retrieve the full details of a previously saved context by its ID. Use this after finding a context via search or list, when the user wants to see the complete content of a specific saved memory. Typically used as a follow-up: "show me that decision", "give me the full details on that one".

bridge_search_context

Search through everything that has been saved across conversations. Use when the user asks "what did I decide about...", "what do we know about...", "did I save anything about...", "find my notes on...", "what was that thing about...", or any question that might be answered by previously saved context. Also use proactively when the user asks a question that saved context might answer — check before saying "I don't have that information". Searches across all surfaces (Chat, Code, Cowork) and all projects.
