# Release Notes: v2.141.0 - MCP Phase 2 Complete
**Release Date:** October 6, 2025
**Type:** Minor Release (MCP Integration)
**Status:** ✅ Ready for Release
**Sprint:** Sprint 22
---
## Overview
v2.141.0 completes MCP Phase 2 by connecting MCP tools to actual CLI implementations. Agents using Claude Code or other MCP clients can now perform real operations instead of receiving mock responses.
**Highlights:**
- 🚀 **Real Operations:** 4 MCP tools connected to actual implementations
- 🔧 **Error Handling:** Comprehensive error reporting with chains
- ⚡ **Parallel Health Checks:** Inherited from v2.140.0 (14-40% faster)
- 🤝 **Agent-Ready:** Production workflows for Claude Code
---
## What's New
### MCP Tool Integrations
#### 1. scaffold_agent - Real Project Scaffolding (PMAT-6017)
Agents can now scaffold actual MCP agent projects via the MCP protocol.
**Before:**
```json
{
"success": true,
"message": "Agent scaffolded successfully" // Mock only!
}
```
**After:**
```json
{
"success": true,
"data": {
"project_name": "my-agent",
"template": "mcp-server",
"output_dir": "./my-agent",
"quality_level": "extreme",
"message": "Agent project 'my-agent' scaffolded successfully"
}
}
```
**Features:**
- Real file creation on disk
- Template selection (mcp-server, stateful, hybrid, calculator)
- Quality levels (standard, high, extreme)
- Feature flags support
- Configurable output directory
**Usage in Claude Code:**
```
Use the scaffold_agent tool to create a new stateful agent
called "github-watcher" with extreme quality level
```
---
#### 2. validate_roadmap - Real Roadmap Validation (PMAT-6019)
Agents can now validate roadmap structure and ticket consistency.
**Features:**
- Real roadmap file parsing
- Ticket file existence checks
- Checkbox/status consistency verification
- Detailed error and warning reporting
**Example Response:**
```json
{
"success": true,
"data": {
"valid": false,
"errors": [
"Missing ticket file: TICKET-PMAT-9999.md"
],
"warnings": [
"TICKET-PMAT-6001: Checked in roadmap but status is Red"
],
"message": "1 error(s) found"
}
}
```
---
#### 3. health_check - Real Project Health Checks (PMAT-6020)
Agents can now run actual health checks with parallel execution.
**Features:**
- Real build checks (`cargo check`)
- Real test execution (`cargo test`)
- Real coverage analysis (`cargo llvm-cov`)
- Complexity checks
- SATD detection
- Parallel execution (14-40% faster from PMAT-6010)
**Example Response:**
```json
{
"success": true,
"data": {
"healthy": true,
"checks": [
{
"name": "Build",
"status": "Pass",
"message": "Project builds successfully"
},
{
"name": "Tests",
"status": "Pass",
"message": "All tests passed"
}
],
"summary": {
"total_checks": 2,
"passed": 2,
"failed": 0
}
}
}
```
---
#### 4. generate_tickets - Real Ticket Generation (PMAT-6021)
Agents can now generate actual ticket files from roadmap entries.
**Features:**
- Real ticket file creation
- Sprint auto-detection from roadmap context
- Status mapping (checkbox state → ticket status)
- Dry-run mode for preview
- Skips existing tickets
**Example Response:**
```json
{
"success": true,
"data": {
"generated": 3,
"generated_tickets": [
"TICKET-PMAT-7001",
"TICKET-PMAT-7002",
"TICKET-PMAT-7003"
],
"skipped": 5,
"message": "Generated 3 ticket file(s)"
}
}
```
**Time Savings:** 10+ minutes per ticket → 1 second
---
### Error Handling Infrastructure (PMAT-6022)
Added comprehensive error handling for all MCP operations.
**New Type:**
```rust
pub struct McpOperationResult {
pub success: bool,
pub data: Option<Value>,
pub error: Option<String>,
pub error_details: Option<Vec<String>>,
}
```
**Benefits:**
- **Consistent Format:** All tools return same structure
- **Error Chains:** Full context for debugging
- **Agent-Friendly:** Clear error messages
- **Graceful Handling:** No protocol violations
**Example Error Response:**
```json
{
"success": false,
"error": "Missing required parameter: 'name'",
"error_details": [
"Missing required parameter: 'name'",
"Parameter extraction failed"
]
}
```
---
## Architecture Improvements
### Code Reuse Pattern
Refactored CLI handlers to extract reusable internal functions:
```
MCP Handler → *_internal() ← CLI Wrapper
↓
Business Logic
```
**Benefits:**
- Zero duplication between CLI and MCP
- Single source of truth
- Easier testing
- Maintainable codebase
**Example:**
```rust
// Shared business logic
pub async fn validate_roadmap_internal(...) -> Result<RoadmapValidation>
// CLI uses it
async fn validate_roadmap(...) -> Result<()> {
let validation = validate_roadmap_internal(...).await?;
print_validation(&validation);
}
// MCP uses it
async fn validate_roadmap_internal(...) -> Result<Value> {
let validation = validate_roadmap_internal(...).await?;
Ok(json!(validation))
}
```
---
## Breaking Changes
**None.** This release is fully backward compatible with v2.140.0.
All existing CLI commands work identically:
```bash
pmat scaffold agent my-agent --template mcp-server # Works as before
pmat maintain roadmap --validate # Works as before
pmat maintain health --quick # Works as before
```
---
## Upgrade Guide
### From v2.140.0
No migration needed. Simply upgrade:
```bash
cargo install pmat --version 2.141.0
```
### Testing Your Upgrade
```bash
# Verify version
pmat --version # Should show: pmat 2.141.0
# Test MCP tools (if using Claude Code or MCP client)
# scaffold_agent, validate_roadmap, health_check, generate_tickets
# Test CLI (should work identically)
pmat maintain health --quick
pmat maintain roadmap --validate
```
---
## Performance
### Inherited from v2.140.0
- **Health Checks:** 14-40% faster via parallel execution
- Two checks: 70s → 60s (14% faster)
- Five checks: ~200s → ~120s (40% faster)
### New Automation
- **Ticket Generation:** 10+ minutes → 1 second per ticket
- **Real Operations:** Actual work being done (file I/O, builds, tests)
---
## Known Issues
### 1. scaffold_wasm Not Connected
**Issue:** `scaffold_wasm` MCP tool still returns mock data
**Reason:** No WASM scaffolding implementation exists in codebase
**Workaround:** Not applicable
**Fix:** Planned for future sprint (requires WASM scaffolding engine)
### 2. Long Operations May Timeout
**Issue:** Large scaffolding operations or comprehensive health checks may timeout
**Workaround:** Use `quick` mode for health checks, smaller templates for scaffolding
**Fix:** Planned for Sprint 23 (progress streaming)
### 3. No Progress Reporting
**Issue:** MCP operations run silently until completion
**Workaround:** Use dry-run mode where available
**Fix:** Planned for Sprint 23 (MCP progress notifications)
