From bd3baf8dd28ea089745c1319d391b202249dfb1f Mon Sep 17 00:00:00 2001 From: mars167 Date: Mon, 2 Feb 2026 00:41:03 +0800 Subject: [PATCH] refactor(mcp): restructure MCP server with registry pattern and Zod validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING: Internal MCP server architecture changed (no API changes) ## What Changed ### Complete Module Separation - Split monolithic 826-line server.ts into focused modules: - types.ts: Shared types and response helpers - registry.ts: Handler registry with Zod validation - schemas/: Type-safe Zod schemas for all 21 tools - handlers/: Extracted handler logic (6 files) - tools/: Tool metadata definitions (5 files) ### Architecture Improvements - Handler registry pattern replaces 400-line if-else chain - Zod schema validation for all tool parameters - Consistent error handling via successResponse/errorResponse helpers - Type-safe tool handlers with proper TypeScript types - Single Responsibility: each module has one clear purpose ### Code Quality - Removed unsafe `as any` casts throughout - Proper type inference from Zod schemas - Consistent error response structure - Better separation of concerns ## File Structure src/mcp/ ├── server.ts (826 → 135 lines, -84%) ├── types.ts (shared types & helpers) ├── registry.ts (tool registration & dispatch) ├── schemas/ (Zod validation) │ ├── repoSchemas.ts │ ├── fileSchemas.ts │ ├── searchSchemas.ts │ ├── astGraphSchemas.ts │ └── dsrSchemas.ts ├── handlers/ (business logic) │ ├── repoHandlers.ts │ ├── fileHandlers.ts │ ├── searchHandlers.ts │ ├── astGraphHandlers.ts │ └── dsrHandlers.ts └── tools/ (metadata definitions) ├── repoTools.ts ├── fileTools.ts ├── searchTools.ts ├── astGraphTools.ts └── dsrTools.ts ## Testing - ✅ All existing tests pass - ✅ TypeScript compilation clean - ✅ No LSP diagnostics - ✅ Build produces identical output ## Backward Compatibility - ✅ No API changes - ✅ All 21 tools work identically - ✅ MCP protocol unchanged - ✅ Access logging preserved --- .git-ai/lancedb.tar.gz | 4 +- src/mcp/handlers/astGraphHandlers.ts | 285 ++++++++++ src/mcp/handlers/dsrHandlers.ts | 75 +++ src/mcp/handlers/fileHandlers.ts | 86 +++ src/mcp/handlers/index.ts | 6 + src/mcp/handlers/repoHandlers.ts | 81 +++ src/mcp/handlers/searchHandlers.ts | 256 +++++++++ src/mcp/registry.ts | 38 ++ src/mcp/schemas/astGraphSchemas.ts | 67 +++ src/mcp/schemas/dsrSchemas.ts | 31 ++ src/mcp/schemas/fileSchemas.ts | 18 + src/mcp/schemas/index.ts | 5 + src/mcp/schemas/repoSchemas.ts | 49 ++ src/mcp/schemas/searchSchemas.ts | 58 ++ src/mcp/server.ts | 775 ++------------------------- src/mcp/tools/astGraphTools.ts | 123 +++++ src/mcp/tools/dsrTools.ts | 65 +++ src/mcp/tools/fileTools.ts | 33 ++ src/mcp/tools/index.ts | 71 +++ src/mcp/tools/repoTools.ts | 76 +++ src/mcp/tools/searchTools.ts | 65 +++ src/mcp/types.ts | 101 ++++ 22 files changed, 1633 insertions(+), 735 deletions(-) create mode 100644 src/mcp/handlers/astGraphHandlers.ts create mode 100644 src/mcp/handlers/dsrHandlers.ts create mode 100644 src/mcp/handlers/fileHandlers.ts create mode 100644 src/mcp/handlers/index.ts create mode 100644 src/mcp/handlers/repoHandlers.ts create mode 100644 src/mcp/handlers/searchHandlers.ts create mode 100644 src/mcp/registry.ts create mode 100644 src/mcp/schemas/astGraphSchemas.ts create mode 100644 src/mcp/schemas/dsrSchemas.ts create mode 100644 src/mcp/schemas/fileSchemas.ts create mode 100644 src/mcp/schemas/index.ts create mode 100644 src/mcp/schemas/repoSchemas.ts create mode 100644 src/mcp/schemas/searchSchemas.ts create mode 100644 src/mcp/tools/astGraphTools.ts create mode 100644 src/mcp/tools/dsrTools.ts create mode 100644 src/mcp/tools/fileTools.ts create mode 100644 src/mcp/tools/index.ts create mode 100644 src/mcp/tools/repoTools.ts create mode 100644 src/mcp/tools/searchTools.ts create mode 100644 src/mcp/types.ts diff --git a/.git-ai/lancedb.tar.gz b/.git-ai/lancedb.tar.gz index a9fce4f..55cc7c2 100644 --- a/.git-ai/lancedb.tar.gz +++ b/.git-ai/lancedb.tar.gz @@ -1,3 +1,3 @@ version https://git-lfs.github.com/spec/v1 -oid sha256:2acdc2fd613d523225880fe284363e9786c83722e22fdca829af10611f2d19ae -size 268403 +oid sha256:4486536ab53f21b3b7b30f42440bd748455bd2af8346245d26de813562e70aae +size 270647 diff --git a/src/mcp/handlers/astGraphHandlers.ts b/src/mcp/handlers/astGraphHandlers.ts new file mode 100644 index 0000000..ebcd448 --- /dev/null +++ b/src/mcp/handlers/astGraphHandlers.ts @@ -0,0 +1,285 @@ +import type { ToolHandler } from '../types';
