Intelligent Planning MCP with Optional Dependencies and Graceful Fallbacks - wise planning through the Force of lean excellence
npm install yoda-mcp




> A Model Context Protocol (MCP) server that provides wise planning through the Force of lean excellence - now with optional external MCP dependencies and graceful fallbacks for resilient offline operation.
NEW in v1.0.1: Revolutionary Optional Dependency Architecture that works flawlessly offline while leveraging external MCPs when available.
Unlike traditional MCPs that break when dependencies fail, yoda-mcp implements:
- ๐ Optional External MCP Dependencies - Enhances capabilities when available, works without them
- ๐ก๏ธ Graceful Fallback System - Local implementations ensure functionality never breaks
- ๐ก Health Monitoring - Automatic detection and graceful handling of unavailable services
- โก Always Available - Core planning functionality works 100% offline
- ๐ง Smart Enhancement - External MCPs add intelligence when present, doesn't depend on them
``bash`
npm install yoda-mcp
`javascript
import { LeanPlannerServer } from 'yoda-mcp';
const planner = new LeanPlannerServer();
// Works completely offline - no external dependencies required
const result = await planner.generatePlan({
goal: "Build a todo application with user authentication",
context: "React frontend with Node.js backend",
simplicityPreference: 'focused'
});
console.log(Plan generated in ${result.performance.totalTime}ms);External servers used: ${result.performance.serversUsed.join(', ')}
console.log();Fallbacks triggered: ${result.performance.fallbacksTriggered.join(', ')}
console.log();`
When external MCPs are available, yoda-mcp automatically leverages them:
`javascript
// Same code - automatically enhanced if external MCPs available:
// - Sequential MCP for advanced requirements analysis
// - TodoList MCP for specialized task breakdown
// - Context7 MCP for best practices and patterns
// - Serena MCP for contextual intelligence
const enhancedResult = await planner.generatePlan({
goal: "Build a fintech API with advanced security",
context: "Production-ready with compliance requirements",
complexityFlags: ['--security', '--architecture'],
simplicityPreference: 'comprehensive'
});
// Result includes which external MCPs were used vs fallbacks
`
yoda-mcp implements an intelligent MCP Service Registry that:
1. Health Monitoring: Automatic detection of available external MCPs
2. Smart Routing: Routes requests to best available service
3. Graceful Degradation: Falls back to local implementations seamlessly
4. Performance Tracking: Monitors response times and availability
| MCP Server | Purpose | Fallback Strategy |
|------------|---------|------------------|
| Sequential MCP | Advanced requirements analysis | โ Local pattern-based analysis |
| TodoList MCP | Specialized task breakdown | โ Template-based task generation |
| Context7 MCP | Best practices & patterns | โ Built-in common practices |
| Serena MCP | Contextual intelligence | โ Simple context parsing |
`javascript
// โ
BEFORE: Traditional MCP (brittle)
if (!sequentialMCP.isAvailable()) {
throw new Error("Sequential MCP required but unavailable");
}
// โ
AFTER: yoda-mcp (resilient)
const requirements = await this.getRequirements(request);
// โ Automatically tries Sequential โ Serena โ Local fallback
// User gets results regardless of external MCP availability
`
yoda-mcp implements genuine lean planning principles:
- ๐ฏ Smart Resource Optimization: Identifies tasks that deliver 80% of value with 20% of effort
- โก Focused Execution: Prioritizes high-impact activities first
- ๐ Iterative Enhancement: Builds core value, then adds complexity only when requested
- ๐ Evidence-Based: All recommendations backed by measurable analysis
`javascript
// Quick planning - Ultra-fast minimal plans
const quickPlan = await planner.generateQuickPlan("Build user auth", 15000);
// Standard planning - Balanced approach
const standardPlan = await planner.generatePlan({
goal: "Build user auth",
simplicityPreference: 'focused'
});
// Enhanced planning - Full analysis with external MCPs
const enhancedPlan = await planner.generatePlan({
goal: "Build user auth",
complexityFlags: ['--security', '--patterns'],
simplicityPreference: 'comprehensive'
});
`
yoda-mcp guarantees functionality even when:
- โ Internet connection is unavailable
- โ External MCP servers are down
- โ Network timeouts occur
- โ Authentication to external services fails
Requirements Analysis: Pattern-based analysis extracts must-have vs should-have requirements
`javascript`
// Automatically detects patterns like:
"todo app" โ Creates/Read/Update/Delete requirements
"auth system" โ Registration/Login/Session requirements
"API service" โ CRUD/Validation/Error handling requirements
Task Generation: Template-based task breakdown with realistic estimates
`javascript`
// Generates appropriate tasks like:
"Design data structure" (4-6 hours)
"Implement core logic" (8-12 hours)
"Create user interface" (6-8 hours)
"Add testing & validation" (4-6 hours)
Context Enrichment: Built-in best practices and common patterns
`javascript`
// Provides essential patterns:
Architecture: MVC, Repository, Dependency Injection
Principles: SOLID, DRY, KISS, YAGNI
Technology: Framework-specific recommendations
- Response Time: <2 seconds for most plans (measured)
- Availability: 100% uptime (offline capability)
- Memory Usage: Minimal footprint maintained
- External MCP Timeout: 30 seconds with graceful fallback
`
๐ TYPICAL PERFORMANCE:
โ
Offline Planning: 245ms (local fallbacks only)
โ
Enhanced Planning: 1,847ms (with 2 external MCPs)
โ
Mixed Mode: 892ms (1 external MCP, 2 fallbacks)
๐ก๏ธ RELIABILITY METRICS:
โ
Plans Generated: 100% (never fails)
โ
External MCP Success Rate: 87% (when available)
โ
Fallback Activation: 13% (seamless experience)

`javascript
import { LeanOrchestrator } from 'yoda-mcp';const orchestrator = new LeanOrchestrator();
// Check current MCP server status
const status = orchestrator.getServerStatus();
console.log(status);
// {
// "sequential": { available: true, responseTime: 245, lastChecked: "..." },
// "todolist": { available: false, lastChecked: "..." },
// "context7": { available: true, responseTime: 891, lastChecked: "..." }
// }
`๐ญ MCP Flag Integration
yoda-mcp integrates seamlessly with Claude Code flags:
`javascript
// --plan flag - Standard planning
await mcpFlagHandler.handlePlanFlag("Build a REST API for user management --security");// --yoda flag - Planning with Yoda wisdom
await mcpFlagHandler.handleYodaFlag("Build a REST API --architecture");
// --plnr flag - Quick planning (15-second limit)
await mcpFlagHandler.handleQuickPlanFlag("Build a REST API");
