Retrieve Context ```python # Find relevant past conversations relevant = historian.search( query="How did we implement authentication?", limit=5 ) for conv in relevant: print(f"Date: {conv.timestamp}") print(f"Summary: {conv.summary}") ``` #### 3. Inject History ```python # Add relevant history to current conversation context = historian.get_context( current_query="Continue the refactoring discussion", max_tokens=2000 ) messages = [ {"role": "system", "content": f"Previous context: {context}"}, {"role": "user", "content": current_query} ] ``` ### Configuration ```json { "mcpServers": { "claude-historian": { "command": "npx", "args": ["-y", "@anthropic/mcp-historian"], "env": { "HISTORIAN_STORAGE": "~/.claude-history", "MAX_HISTORY_SIZE": "10000" } } } } ``` ### Use Cases **Project Continuity**: Resume discussions from previous sessions. **Knowledge Accumulation**: Build on past solutions and decisions. **Team Context**: Share conversation history across team members.
