- Remove readonly from indexNames and indexes fields - Remove empty-index checks at initialization (allow zero indexes) - Add refreshIndexList() method to reload indexes from store - Add invalidateClient() method to clear cached SearchClient - Update MCPServerConfig.store to accept both IndexStoreReader and IndexStore Agent-Id: agent-49436113-35bf-4532-983a-fb01da818555
- Add list_indexes tool to ListToolsRequestSchema handler - Add handler in CallToolRequestSchema that refreshes index list and returns formatted metadata (name, type, identifier, syncedAt) - Returns helpful message when no indexes exist - Add withListIndexesReference() helper in tool-descriptions.ts - Update MCP server to use withListIndexesReference instead of embedding static index list in tool descriptions - Keep withIndexList() for CLI agent backward compatibility Agent-Id: agent-b187383f-2e44-4592-9ec9-6f0f4e0eafb6
- Add delete_index tool definition (only when store supports delete) - Add handler to delete index from store, refresh runner state, and invalidate cached client - Validates index exists before attempting delete - Returns appropriate error messages for missing index or unsupported store Agent-Id: agent-8cf675a5-fcdf-402a-a3a1-f3fa2a8c3f1b

This tool allows creating/updating indexes dynamically from: - GitHub repositories (requires owner and repo) - GitLab repositories (requires project_id) - BitBucket repositories (requires workspace and repo) - Websites (requires url) Features: - Validates required parameters for each source type - Checks if store supports write operations - Refreshes runner state after indexing - Invalidates cached client for updated indexes - Returns success message with stats (type, filesIndexed, duration) Agent-Id: agent-4dd9b0b4-3ecf-4a2a-850a-49fd55aba0b5
Remove the empty-index check from the CLI so the MCP server can start even when no indexes exist. This enables the dynamic indexing workflow where users can call list_indexes (empty) then index_repo to create indexes on-demand.

Summary
This PR adds dynamic index management capabilities to the MCP server, allowing agents to create, list, and delete indexes on-demand.

For dynamic indexing to work, the MCP server must be started without

-iflags, it usesCompositeStoreReader(read-only) andindex_repo/delete_indexwill fail.Commits
