Self-Learning MCP

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 dev

In a second terminal, start the dashboard:

cd Self-Learning-MCP
bun run dev

Open http://localhost:3000 to view the dashboard.

Environment Variables

Variable

Default

Description

DATABASE_URL

file:./db/custom.db

SQLite database path (relative to prisma/schema.prisma)

LOG_LEVEL

info

Logging verbosity: trace, debug, info, warn, error

NODE_ENV

Set to production for production builds

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 build

Creates a standalone .next/ bundle with all static assets. Serve with:

NODE_ENV=production bun .next/standalone/server.js

For production deployments:

  • Use a reverse proxy (Caddy, Nginx) with TLS

  • Set NODE_ENV=production

  • Back up the SQLite database regularly

  • Use knowledge_export for 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.
