 ## MCP Tools
 
-These search tools are available via MCP:
+Four tools are exposed via MCP:
 
-- `search` - semantic search across all memories
-- `timeline` - browse by time
-- `decisions` - find architecture decisions
-- `changes` - find code modifications
-- `how_it_works` - system understanding queries
+- `search` - semantic search across all memories. Accepts `obs_type` (e.g.
+  `decision`, `code_change`, `architecture`) plus filter params (`concepts`,
+  `files`, `type`) - these replace the old per-type shortcut tools.
+- `timeline` - browse observations around a point in time.
+- `observation` - manage individual observations. Set `action` to one of:
+  `get`, `edit`, `delete`, `supersede`, `boost`, `merge`, `related`, `similar`,
+  `quality`, `relationships`, `scoring`, `tag`, `by_tag`, `batch_tag`.
+- `memory_admin` - administration and analytics. Set `action` to one of:
+  `stats`, `health`, `maintenance_stats`, `run_maintenance`, `importance`,
+  `search_patterns`, `explain_ranking`, `temporal_trends`, `data_quality`,
+  `export`, `suggest_consolidations`, `patterns`.

-  { question: 'How does hybrid vector storage work?', answer: 'LEANN-inspired selective storage: frequently-accessed "hub" observations (identified by access patterns and graph centrality) store embeddings.

-  { question: 'What if I switch between projects frequently?', answer: 'That\'s the point. Each project has isolated memories. Switch from your Python ML project to your TypeScript app - context switches automatically.' },
-  { question: 'Is there a performance impact?', answer: 'Minimal. The Go worker is lightweight (typically under 30MB RAM). Hybrid storage and auto-tuning optimize for your workload. Context injection at session start takes milliseconds for most projects.' },
-  { question: 'What is AST-aware chunking?', answer: 'When processing code observations, Mnemonic uses Tree-sitter parsers to respect function and class boundaries instead of arbitrary line limits. Go, Python, and TypeScript code is chunked at semantic boundaries for better search accuracy.' },
