Bruno MCP Server

# Phase 2 Implementation Summary ## Overview Phase 2 focused on adding core features for production use: report generation, collection discovery, and environment management. This document summarizes what was implemented and tested. --- ## Phase 2.1 - Report Generation ✅ COMPLETE (Completed Previously) ### Implementation Details - Integrated Bruno CLI's native reporter flags - Added support for JSON, JUnit XML, and HTML report formats - All report formats can be generated simultaneously - Reports confirmed in output when generated **Files Modified:** - `src/index.ts` - Added reporter parameters to tool schemas - `src/bruno-cli.ts` - Added reporter options to Bruno CLI execution - `README.md` - Documented report generation features **Test Results:** - ✅ JSON report generation - ✅ JUnit XML report generation - ✅ HTML report generation - ✅ Multiple format generation simultaneously --- ## Phase 2.2 - Collection Discovery ✅ COMPLETE ### Implementation Details **New Tool: `bruno_discover_collections`** Recursively searches for Bruno collections (directories containing `bruno.json` files) in a workspace. **Features:** 1. **Recursive Search** - Configurable maximum depth (default: 5, max: 10) - Skips hidden directories (`.git`, etc.) - Skips `node_modules` directories - Stops recursion when collection found (doesn't search subdirectories of collections) 2. **Smart Detection** - Identifies collections by `bruno.json` file presence - Returns full absolute paths - Handles permission errors gracefully 3. **Security Integration** - Path validation via security module - Respects configured allowed paths **Code Added:** - [src/bruno-cli.ts:748-786](src/bruno-cli.ts#L748-L786) - `discoverCollections()` method - [src/index.ts:530-580](src/index.ts#L530-L580) - `handleDiscoverCollections()` handler **Example Usage:** ```typescript bruno_discover_collections({ searchPath: "/path/to/workspace", maxDepth: 5 }) ``` **Example Output:** ``` Found 3 Bruno collection(s): 1. /path/to/workspace/api-tests 2. /path/to/workspace/projects/integration-tests 3. /path/to/workspace/e2e-tests ``` --- ## Phase 2.3 - Environment Management ✅ COMPLETE ### Tool 1: `bruno_list_environments` Lists all environment files (`.bru`) in a collection's `environments` directory. **Features:** 1. **Environment Discovery** - Scans `environments` directory for `.bru` files - Parses variables from each environment file - Returns environment name, path, and variables 2. **Variable Parsing** - Parses `vars { ... }` blocks from `.bru` files - Extracts key-value pairs - Handles multi-line variable definitions 3. **Secret Masking** - Automatically masks variables with sensitive names: - `password`, `secret`, `token`, `key` - Shows `***` for masked values - Truncates long values in preview **Code Added:** - [src/bruno-cli.ts:791-831](src/bruno-cli.ts#L791-L831) - `listEnvironments()` method - [src/bruno-cli.ts:900-921](src/bruno-cli.ts#L900-L921) - `parseEnvironmentVariables()` helper - [src/index.ts:582-653](src/index.ts#L582-L653) - `handleListEnvironments()` handler **Example Usage:** ```typescript bruno_list_environments({ collectionPath: "/path/to/collection" }) ``` **Example Output:** ``` Found 2 environment(s): • dev Path: /path/to/collection/environments/dev.bru Variables: 3 - baseUrl: https://jsonplaceholder.typicode.com - apiKey: *** - timeout: 5000 • staging Path: /path/to/collection/environments/staging.bru Variables: 3 - baseUrl: https://api.staging.example.com - apiKey: *** - timeout: 10000 ``` ### Tool 2: `bruno_validate_environment` Validates an environment file's structure, syntax, and detects potential security issues. **Features:** 1. **Existence Check** - Verifies environment file exists - Returns clear error if not found 2. **Structure Validation** - Checks for `vars { }` block - Warns if no variables defined - Validates file readability 3. **Security Warnings** - Detects hardcoded sensitive data - Warns about password/secret/token variables with non-dynamic values - Checks if values use variable references (`{{...}}`) or env vars (`$...`) 4. **Variable Parsing** - Parses and displays all variables - Masks sensitive values in output - Returns full variable list **Code Added:** - [src/bruno-cli.ts:836-895](src/bruno-cli.ts#L836-L895) - `validateEnvironment()` method - [src/index.ts:655-733](src/index.ts#L655-L733) - `handleValidateEnvironment()` handler **Example Usage:** ```typescript bruno_validate_environment({ collectionPath: "/path/to/collection", environmentName: "dev" }) ``` **Example Output (Valid):** ``` === Environment Validation: dev === ✅ Status: Valid Variables: 3 baseUrl: https://jsonplaceholder.typicode.com apiKey: *** (masked) timeout: 5000 ``` **Example Output (Not Found):** ``` === Environment Validation: production === ❌ Status: Not Found Errors: • Environment file not found: /path/to/collection/environments/production.bru ``` ### Tool 3: Environment Switching Environment switching is already supported through the existing `bruno_run_request` and `bruno_run_collection` tools via the `environment` parameter. No additional implementation needed. **Usage:** ```typescript // Switch to different environments when running bruno_run_request({ collectionPath: "/path/to/collection", requestName: "Get Users", environment: "dev" // or "staging", "production", etc. }) ``` --- ## Test Results ### New Test Script: `test-phase2.js` Created comprehensive test suite covering: 1. **Test 1: Discover Collections** - ✅ Finds test collection in workspace - ✅ Returns correct path - ✅ Handles configurable depth 2. **Test 2: List Environments** - ✅ Lists all environments in collection - ✅ Parses variables correctly - ✅ Masks sensitive values 3. **Test 3: Validate Valid Environment** - ✅ Validates existing environment - ✅ Shows all variables - ✅ Masks secrets in output 4. **Test 4: Validate Non-Existent Environment** - ✅ Handles missing environment gracefully - ✅ Returns clear error message - ✅ Marks as invalid with errors **All Phase 2 tests: 4/4 passing ✅** ### Integration Testing **MCP Server Test Suite:** - ✅ All 5 existing tests still passing - ✅ Tool count increased from 4 to 7 tools - ✅ No regressions in existing functionality **Total Test Coverage:** - Phase 1: 5 tests (MCP integration) - Phase 2: 4 tests (new features) + 2 tests (reports) - Phase 3: 13 tests (security) + 4 tests (config) + 4 tests (health) - **Grand Total: 32/32 tests passing ✅** --- ## Files Created/Modified ### New Files - [test-phase2.js](test-phase2.js) - Phase 2 feature testing - [PHASE2-SUMMARY.md](PHASE2-SUMMARY.md) - This document ### Modified Files 1. **src/bruno-cli.ts** (+176 lines) - Added `discoverCollections()` method - Added `listEnvironments()` method - Added `validateEnvironment()` method - Added `parseEnvironmentVariables()` helper 2. **src/index.ts** (+213 lines) - Added 3 new tool schemas (DiscoverCollections, ListEnvironments, ValidateEnvironment) - Added 3 new tool definitions to TOOLS array - Added 3 new case statements in switch - Added 3 new handler methods 3. **README.md** - Added documentation for 3 new tools - Added example usage and outputs - Updated completed features list - Updated project structure 4. **ROADMAP.md** - Marked Phase 2 as 100% complete (10/10 items) - Added completion notes for each section - Updated implementation details --- ## Key Features & Highlights ### 1.
