+## 2025-12-04 16:58 - Task 1 Completed
+
+### Summary
+- Created `~/.config/opencode/plugin/mcp-loader.ts` - Plugin skeleton with config loader
+- Created `~/.config/opencode/plugin/mcp-loader.test.ts` - 14 unit tests
+
+### Key Implementation Details
+- Config merge: project overrides global for same server names, merges different
+- Env var substitution: `{env:VAR}` → `process.env.VAR`
+- Validation: type required, local needs command, remote needs url
+- Empty config returns `{ servers: {} }` (not error)
+
+### Test Results
+- 14 tests passed
+- substituteEnvVars: 4 tests
+- substituteHeaderEnvVars: 1 test
+- loadConfig: 9 tests
+
+### Files Created
+- `~/.config/opencode/plugin/mcp-loader.ts`
+- `~/.config/opencode/plugin/mcp-loader.test.ts`
