Self-Learning MCP
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Self-Learning MCPSearch memory for recent debugging notes on race conditions"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Self-Learning MCP
An MCP (Model Context Protocol) server that gives AI coding assistants durable long-term memory, reusable skills, a knowledge graph, post-task reflection, and evidence-based decision intelligence. Runs fully offline with no external API keys.
Created by Abhradeep Paul Chowdhury.
Features
Memory Engine — Store decisions, bugs, fixes, conventions, architecture notes, and prompt outcomes. Semantic search with deterministic hash-based embeddings (256-dim, cosine similarity).
Skill Engine — Create versioned, executable engineering workflows. Auto-learning from repeated successful outcomes.
Knowledge Graph — Nodes and edges across 11 entity types and 7 relationship types. Multi-hop BFS traversal.
Reflection Engine — Post-task analysis with heuristic root-cause categorization. Automatically creates skills from patterns that succeed 3+ times.
Planner — Decompose goals into ordered multi-step plans (build, debug, deploy, refactor, research). Execution loop with auto-retry and reflection.
Decision Intelligence Engine — Evidence-backed decisions with a 9-tier evidence hierarchy. Separates verified facts from assumptions. Refuses high-impact decisions when confidence falls below threshold.
Workspace & Knowledge Management — Project tracking, deployment history, code pattern analysis, full JSON export/import.
Web Dashboard — Next.js UI to visualize and operate all engines (8 tabs: Overview, Memory, Skills, Graph, Reflections, Planner, Decisions, Connect).

└──────────────────────────────────────────┘The server runs in two modes:
In-process — All engines load inside the Next.js dashboard process (default, recommended)
Standalone — Hono HTTP server on port 3003 + separate MCP stdio bridge for AI clients
Both modes share the same engines and the same SQLite database.

Quick Start
# Prerequisites: Bun >= 1.3, Node.js >= 20
git clone https://github.com/abhraweb-boop/Self-Learning-MCP.git
cd Self-Learning-MCP
# Install root dependencies (dashboard + Prisma)
bun install
# Install MCP server dependencies
cd mini-services/mcp-server && bun install && cd ../..
# Copy environment config
cp .env.example .env
# Push database schema
bun run db:push
# (Optional) Seed demo data
cd mini-services/mcp-server && bun run seed && cd ../..
# Start the standalone HTTP server
cd mini-services/mcp-server && bun run devIn a second terminal, start the dashboard:
cd Self-Learning-MCP
bun run devOpen http://localhost:3000 to view the dashboard.

Connecting AI Clients
Configure your MCP client to spawn bun run mcp from the mini-services/mcp-server directory:
{
"mcpServers": {
"self-learning": {
"command": "bun",
"args": ["run", "mcp"],
"cwd": "/absolute/path/to/mini-services/mcp-server"
}
}
}Works with Claude Code, Cursor, OpenCode, VS Code (with an MCP extension), and any MCP-compatible client.
Production Build
bun run buildCreates a standalone .next/ bundle with all static assets. Serve with:
NODE_ENV=production bun .next/standalone/server.jsFor production deployments:
Use a reverse proxy (Caddy, Nginx) with TLS
Set
NODE_ENV=productionBack up the SQLite database regularly
Use
knowledge_exportfor portable JSON backups

Example Usage
Remember a decision:
User: Remember that we use App Router for all pages.
Agent: [calls remember with type=decision, title="Use App Router"...]Evaluate a decision with evidence:
User: Should we switch from SQLite to PostgreSQL?
Agent: [calls decide with facts about traffic, cost, migration effort...]
Returns: Refused — insufficient evidence (confidence 35%, threshold 60%).
Requests more information: traffic metrics, cost comparison, migration plan.Analyze a failure and auto-learn:
User: The deployment failed because the build ran out of memory.
Agent: [calls analyze_failure with goal="Deploy API" and error details]
Creates: reflection + prompt_failure memory.
After 3 similar failures: auto-creates a "deploy-api" skill with extra swap.License
