+# Contribution Summary
+
+## Fixed Issues
+
+This contribution fixes three issues from the obsidian-mcp-tools repository:
+
+### 1. Issue #37: Trailing slash bug causing HTTP 500 errors
+**Problem**: When `list_vault_files` is called with a directory parameter containing a trailing slash (e.g., `"DevOps/"`), it creates a double slash in the URL (`/vault/DevOps//`) which causes a 404 error wrapped in a 500 response.
+
+**Solution**:
+- Created `normalizeDirectory()` utility function to strip trailing slashes
+- Updated `list_vault_files` tool to normalize directory paths before constructing URLs
+- Added comprehensive tests
+
+**Files changed**:
+- `packages/mcp-server/src/shared/normalizePath.ts` (new)
+- `packages/mcp-server/src/shared/normalizePath.test.ts` (new)
+- `packages/mcp-server/src/features/local-rest-api/index.ts`
+
+---
+
+### 2. Issue #36: Duplicate /home/<user> in download path
+**Problem**: On systems with symlinked home directories, the install path contains duplicate path segments (e.g., `/home/user/home/user/vault/.obsidian/plugins/mcp-tools/bin`).
+
+**Solution**:
+- Created `normalizeDuplicateSegments()` utility to detect and remove repeating path patterns
+- Applied normalization to install paths after symlink resolution
+- Added comprehensive tests including real-world scenarios
+
+**Files changed**:
+- `packages/obsidian-plugin/src/features/mcp-server-install/utils/normalizePath.ts` (new)
+- `packages/obsidian-plugin/src/features/mcp-server-install/utils/normalizePath.test.ts` (new)
+- `packages/obsidian-plugin/src/features/mcp-server-install/services/status.ts`
+
+---
+
+### 3. Issue #26: Platform selection for MCP server binary
+**Problem**: Users running Obsidian on Windows but wanting to use the Linux MCP server in WSL had no way to override the auto-detected platform.
+
+**Solution**:
+- Extended `McpToolsPluginSettings` with custom configuration options:
+  - `customPlatform`: Override detected OS platform
+  - `customArch`: Override detected architecture
+  - `customBinaryPath`: Custom binary location
+  - `customCommand`: Custom wrapper command (e.g., wsl.exe)
+  - `customEnvVars`: Additional environment variables
+  - `customHost`: Custom server host
+- Updated `getPlatform()` and `getArch()` to check settings first
+- Modified `updateClaudeConfig()` to use custom command and environment variables
+- Added tests for platform override functionality
+
+**Example use case** (WSL):
+```typescript
+{
+  customPlatform: "linux",
+  customCommand: "wsl.exe --distribution Ubuntu -- bash -c \"mcp-server-bin\"",
+  customEnvVars: {
+    OBSIDIAN_API_KEY: "your-key",
+    CUSTOM_VAR: "value"
+  },
+  customHost: "127.0.0.1"
+}
+```
+
+**Files changed**:
+- `packages/obsidian-plugin/src/types.ts`
+- `packages/obsidian-plugin/src/features/mcp-server-install/services/install.ts`
+- `packages/obsidian-plugin/src/features/mcp-server-install/services/status.ts`
+- `packages/obsidian-plugin/src/features/mcp-server-install/services/config.ts`
+- `packages/obsidian-plugin/src/features/mcp-server-install/services/install.test.ts` (new)
+
+---
+
+## Test Coverage
+
+All fixes include comprehensive unit tests:
+
+**Test files**:
+- `packages/mcp-server/src/shared/normalizePath.test.ts` - 9 tests covering path normalization
+- `packages/obsidian-plugin/src/features/mcp-server-install/utils/normalizePath.test.ts` - 10 tests for duplicate segment detection
+- `packages/obsidian-plugin/src/features/mcp-server-install/services/install.test.ts` - 8 tests for platform/arch override
+
+**Test results**: All 19 new tests pass ✅
+
+---
+
+## Build Verification
+
+Both packages build successfully:
+- ✅ `packages/mcp-server` - Compiled successfully
+- ✅ `packages/obsidian-plugin` - TypeScript compilation successful
+

+## Commits
+
+The changes are organized into 4 commits:
+
+1. `ad21259` - fix: normalize directory paths to prevent double slashes (#37)
+2. `b09e51b` - fix: remove duplicate path segments in install path (#36)
+3. `15db9ea` - feat: add platform and architecture selection for MCP server (#26)
+4. `70e6f38` - chore: update bun.lock after dependency installation
+
+---
+
+## Development Approach
+
+All fixes were developed using **Test-Driven Development (TDD)**:
+1. Write failing tests first
+2. Implement the minimal code to make tests pass
+3. Refactor for clarity and maintainability
+4. Verify all tests pass and build succeeds
+
