# Centralized Index Storage Implementation ## Summary of Changes We've successfully simplified the MCP index storage to use a single centralized location at `~/.mcp/indexes/`. This eliminates confusion about which index is being used and prevents indexes from being accidentally committed to git. ### Key Changes Made: 1. **Single Storage Location** - All indexes now stored at: `~/.mcp/indexes/{repo_hash}/{branch}_{commit}.db` - Removed support for local `.mcp-index/` directories - Removed fallback to `code_index.db` 2. **Simplified MCP Server** - Now only checks the central location - Automatically defaults to `~/.mcp/indexes` if not configured - Provides clear error messages if no index found 3. **Migration Completed** - Moved main repository index to central location - Moved all test repository indexes (10 repositories) - Removed `.mcp-index/` directory from repository - Total of 21 indexes now in central storage 4. **Updated Configuration** - Removed storage strategy options from templates - Simplified `.mcp-index.json` configuration - No need to set `MCP_INDEX_STORAGE_PATH` explicitly ### Repository Structure Each repository gets a unique hash-based directory: ``` ~/.mcp/indexes/ ├── f7b49f5d0ae0/ # Code-Index-MCP main repo │ ├── main_f48abb0.db # Index for main branch at commit f48abb0 │ ├── main_f48abb0.metadata.json │ └── current.db -> main_f48abb0.db ├── 96d34ef1438c/ # go_gin test repo │ ├── test_main.db │ ├── test_bm25.db │ └── current.db -> test_main.db └── ... (other repositories) ``` ### Benefits 1. **No Accidental Commits**: Indexes stored outside repositories 2. **Reusability**: Same index works across multiple clones 3. **Simplicity**: Single location, no confusion 4. **Clean Repos**: No index files in working directories ### Usage For new repositories: 1. Create index with `mcp-index index` 2. Index automatically stored in central location For existing repositories with local indexes: 1. Run `python scripts/move_indexes_to_central.py` 2. Index moved to central location 3. MCP server automatically uses central index The MCP server will show an error if no index exists, with instructions on how to create one.
