<h2>Architecture Overview</h2>
<h3>Server Architecture</h3>
<p>The Darbot Deepmind MCP Server implements a stateful reasoning engine with the following key components:</p>
<div class="code-block">
<pre><code>┌─────────────────────────────────────────┐
│ MCP Client (Claude/VS Code) │
└──────────────────┬──────────────────────┘
│ MCP Protocol
│ (stdio transport)
┌──────────────────▼──────────────────────┐
│ DarbotDeepmindServer Instance │
│ ┌────────────────────────────────────┐ │
│ │ Tool: darbot_deepmind │ │
│ │ - Input Validation (Zod) │ │
│ │ - Thought Processing │ │
│ │ - History Management │ │
│ │ - Branch Tracking │ │
│ └────────────────────────────────────┘ │
│ ┌────────────────────────────────────┐ │
│ │ Thought History │ │
│ │ - Sequential storage │ │
│ │ - Revision tracking │ │
│ │ - Branch mapping │ │
│ └────────────────────────────────────┘ │
│ ┌────────────────────────────────────┐ │
│ │ Console Logger │ │
│ │ - Colored output (Chalk) │ │
│ │ - Configurable verbosity │ │
│ └────────────────────────────────────┘ │
└─────────────────────────────────────────┘</code></pre>
</div>
<h3>Design Patterns</h3>
<h4>1. Schema-First Validation</h4>
<p>All inputs are validated using Zod schemas before processing:</p>
<div class="code-block">
<pre><code>const DeepmindSchema = z.object({
thought: z.string().min(1),
nextThoughtNeeded: z.boolean(),
thoughtNumber: z.number().int().positive(),
totalThoughts: z.number().int().positive(),
isRevision: z.boolean().optional(),
revisesThought: z.number().int().positive().optional(),
branchFromThought: z.number().int().positive().optional(),
branchId: z.string().optional(),
needsMoreThoughts: z.boolean().optional(),
});</code></pre>
</div>
<h4>2. Stateful Reasoning Engine</h4>
<p>The server maintains thought history to enable:</p>
<ul>
<li>Revision validation</li>
<li>Branch tracking</li>
<li>Context awareness</li>
<li>Progress monitoring</li>
</ul>
<h4>3. Structured Response Format</h4>
<p>Consistent JSON responses with metadata:</p>
<div class="code-block">
<pre><code>interface ThoughtResponse {
thoughtNumber: number;
totalThoughts: number;
nextThoughtNeeded: boolean;
branches: string[];
thoughtHistoryLength: number;
isRevision?: boolean;
revisesThought?: number;
branchId?: string;
branchFromThought?: number;
needsMoreThoughts?: boolean;
}</code></pre>
</div>
<h2>Core Concepts</h2>
<h3>Thought Processing</h3>
<p>The framework processes thoughts through these stages:</p>
<ol>
<li><strong>Input Validation:</strong> Zod schema validation of all parameters</li>
<li><strong>Revision Validation:</strong> Ensure revisions reference past thoughts</li>
<li><strong>Branch Validation:</strong> Verify branch points are valid</li>
<li><strong>Adaptive Planning:</strong> Adjust total thoughts dynamically</li>
<li><strong>History Storage:</strong> Maintain ordered thought sequence</li>
<li><strong>Response Generation:</strong> Create structured response with metadata</li>
<li><strong>Console Logging:</strong> Format and display thought (if enabled)</li>
</ol>
<h3>Thought Revision</h3>
<p>Revision mechanism allows reconsidering previous thoughts:</p>
<ul>
<li><strong>Validation:</strong> Ensures revised thought exists and is in the past</li>
<li><strong>Context:</strong> Maintains connection to original thought</li>
<li><strong>Tracking:</strong> Records revision relationships in history</li>
</ul>
<div class="alert alert-info">
<strong>Example:</strong> If thought 4 needs revision at thought 7, set <code>isRevision: true</code> and <code>revisesThought: 4</code>
</div>
<h3>Branch Management</h3>
<p>The framework supports exploring alternative solution paths:</p>
<ul>
<li><strong>Branch Point:</strong> Any thought can be a branching point</li>
<li><strong>Branch ID:</strong> Unique identifier for each branch</li>
<li><strong>Parallel Exploration:</strong> Multiple branches can coexist</li>
<li><strong>Branch Tracking:</strong> Server maintains list of active branches</li>
</ul>
<h3>Adaptive Planning</h3>
<p>Dynamic adjustment of thought count:</p>
<ul>
<li>Initial estimate can be adjusted up or down</li>
<li>Automatic adjustment when thought number exceeds total</li>
<li><code>needsMoreThoughts</code> flag for explicit expansion</li>
<li>No penalty for underestimation or overestimation</li>
</ul>
<h2>Implementation Details</h2>
<h3>Validation Logic</h3>
<p>Three-tier validation ensures data integrity:</p>
<div class="code-block">
<pre><code>// 1. Schema Validation (Zod)
const validatedInput = DeepmindSchema.parse(input);
// 2. Revision Validation
if (validatedInput.isRevision) {
if (!validatedInput.revisesThought) {
throw new Error("revisesThought required when isRevision is true");
}
if (validatedInput.revisesThought >= validatedInput.thoughtNumber) {
throw new Error("Can only revise past thoughts");
}
}
// 3. Branch Validation
if (validatedInput.branchId && !validatedInput.branchFromThought) {
throw new Error("branchFromThought required when branchId is set");
}</code></pre>
</div>
<h3>Thought History Management</h3>
<p>Efficient in-memory storage with array-based history:</p>
<ul>
<li>Sequential append-only operations</li>
<li>No deletions (immutable history)</li>
<li>Fast access by index</li>
<li>Branch tracking via separate set</li>
</ul>
<h3>Console Output Formatting</h3>
<p>Colored, bordered output using Chalk and box-drawing characters:</p>
<div class="code-block">
<pre><code>┌─────────────────────────────────────┐
│ Thought 1/8 │
├─────────────────────────────────────┤
│ Analyzing requirements for platform │
│ supporting 1M daily users │
└─────────────────────────────────────┘</code></pre>
</div>
<h2>Performance Considerations</h2>
<h3>Memory Management</h3>
<ul>
<li><strong>Thought History:</strong> Grows linearly with reasoning depth</li>
<li><strong>Branch Set:</strong> Minimal memory overhead for tracking</li>
<li><strong>Recommendation:</strong> For very long chains (100+ thoughts), consider session breaks</li>
</ul>
<h3>Response Time</h3>
<ul>
<li><strong>Validation:</strong> O(1) - Constant time schema validation</li>
<li><strong>Processing:</strong> O(1) - No complex computations</li>
<li><strong>Formatting:</strong> O(n) where n is thought text length</li>
<li><strong>Typical:</strong> Sub-millisecond processing time</li>
</ul>
<h3>Concurrency</h3>
<ul>
<li>Single-threaded Node.js event loop</li>
<li>One reasoning chain per server instance</li>
<li>Stateful design requires dedicated instances for parallel chains</li>
</ul>
<h2>Code Quality Standards</h2>
<h3>TypeScript Configuration</h3>
<p>Strict mode enabled for type safety:</p>
<div class="code-block">
<pre><code>{
"compilerOptions": {
"strict": true,
"noImplicitAny": true,
"strictNullChecks": true,
"strictFunctionTypes": true,
"strictBindCallApply": true,
"strictPropertyInitialization": true,
"noImplicitThis": true,
"alwaysStrict": true
}
}</code></pre>
</div>
<h3>Testing Requirements</h3>
<ul>
<li>80%+ code coverage minimum</li>
<li>Unit tests for all validation logic</li>
<li>Integration tests for MCP protocol</li>
<li>Edge case testing (invalid inputs, boundary conditions)</li>
</ul>
<h3>Code Style</h3>
<ul>
<li>ESLint with TypeScript rules</li>
<li>Prettier for formatting (2 spaces, no tabs)</li>
<li>JSDoc comments for public APIs</li>
<li>Meaningful variable and function names</li>
</ul>
<h2>Build and Deployment</h2>
<h3>Build Process</h3>
<div class="code-block">
<pre><code># Install dependencies
npm ci
# Type checking
npx tsc --noEmit
# Build
npm run build
# Output: dist/index.js (transpiled JavaScript)</code></pre>
</div>
<h3>Docker Build</h3>
<p>Multi-stage build for optimized images:</p>
<div class="code-block">
<pre><code># Stage 1: Builder
FROM node:22-alpine AS builder
WORKDIR /app
COPY package*.json tsconfig.json ./
RUN npm ci --only=production
COPY src ./src
RUN npm run build
# Stage 2: Runtime
FROM node:22-alpine AS runtime
WORKDIR /app
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/node_modules ./node_modules
USER mcp
ENTRYPOINT ["node", "dist/index.js"]</code></pre>
</div>
<h3>CI/CD Pipeline</h3>
<p>GitHub Actions workflow:</p>
<ul>
<li><strong>Linting:</strong> ESLint checks on all commits</li>
<li><strong>Type Checking:</strong> TypeScript compilation without emit</li>
<li><strong>Testing:</strong> Jest with coverage reporting</li>
<li><strong>Build:</strong> TypeScript compilation and verification</li>
<li><strong>Docker:</strong> Image build and smoke test</li>
<li><strong>Coverage:</strong> Codecov integration for tracking</li>
</ul>
<h2>Extension Points</h2>
<h3>Custom Validators</h3>
<p>Extend validation logic by adding custom validators:</p>
<div class="code-block">
<pre><code>validateCustomLogic(input: DeepmindInput): void {
// Add custom validation rules
if (input.thoughtNumber === 13 && input.branchId) {
throw new Error("Branch not allowed at thought 13");
}
}</code></pre>
</div>
<h3>Alternative Output Formats</h3>
<p>Customize console output or add new output channels:</p>
<div class="code-block">
<pre><code>formatThought(input: DeepmindInput): string {
// Custom formatting logic
return `[${input.thoughtNumber}/${input.totalThoughts}] ${input.thought}`;
}</code></pre>
</div>
<h2>Best Practices</h2>
<h3>For Framework Users</h3>
<ul>
<li>Start with conservative thought estimates</li>
<li>Use revisions for significant insights</li>
<li>Branch only when exploring truly different paths</li>
<li>Keep thought descriptions concise but meaningful</li>
<li>Monitor memory usage for very long chains</li>
</ul>
<h3>For Contributors</h3>
<ul>
<li>Maintain backward compatibility for the tool API</li>
<li>Add tests for all new functionality</li>
<li>Document public APIs with JSDoc</li>
<li>Follow existing code patterns and style</li>
<li>Update documentation with changes</li>
</ul>
