SocratiCode

"There is only one good, knowledge, and one evil, ignorance." — Socrates

Your AI reads code. SocratiCode understands it.

The open-source codebase context engine: give any AI instant automated knowledge of your entire codebase (and infrastructure) — at scale, zero configuration, fully private, completely free.

☁️ SocratiCode Cloud (private beta) — Hosted, shared team index built on the same engine as the open-source version, plus SSO, audit logs, branch-aware indexing, and VPC / air-gapped deployment options. The open-source core remains free forever. Request early access →

One thing, done well: deep codebase intelligence with zero setup, no bloat, and full automation. SocratiCode gives AI assistants deep semantic understanding of your codebase: hybrid search, cross-project search, polyglot code dependency graphs, symbol-level impact analysis and flow, interactive HTML graph explorer for visual navigation, and searchable context artifacts (database schemas, API specs, infra configs, architecture docs). Zero configuration: add it to an MCP host that supports local stdio servers, or use a supported plugin or extension. It manages everything automatically.

Production-ready, battle-tested on enterprise-level large repositories (up to and over ~40 million lines of code). Batched, automatic resumable indexing checkpoints progress — pauses, crashes, restarts, and interruptions don't lose work. The file watcher keeps the index automatically updated at every file change and across sessions. Multi-branch, multi-repo and multi-agent ready — multiple AI agents can work on the same codebase simultaneously, sharing a single index with automatic coordination and zero configuration.

Private and local by default — Docker handles everything, no API keys required, no data leaves your machine. Cloud ready for embeddings (OpenAI, Google Gemini) and Qdrant, and a full suite of configuration options are all available when you need them.

Code intelligence that belongs to you, AI and host agnostic — your codebase's understanding lives with the code, not locked to any one assistant, IDE or model. And because SocratiCode pre-computes the hard parts (blast radius, call-flow, dependency traversal), smaller models can handle architectural complex tasks that would otherwise need top-tier reasoning, saving even more on token cost.

The first Qdrant‑based MCP/Claude Plugin/Skill that pairs auto‑managed, zero‑config local Docker deployment with AST‑aware code chunking, hybrid semantic + BM25 (RRF‑fused) code search, polyglot dependency graphs with circular‑dependency visualisation, symbol‑level Impact Analysis (blast‑radius & call‑flow tracing across 18 languages), and searchable infra/API/database artifacts in a single focused, zero-config and easy to use code intelligence engine.

Benchmarked on VS Code (2.45M lines): SocratiCode uses 61% less context, 84% fewer tool calls, and is 37x faster than grep‑based exploration — tested live with Claude Opus 4.6. See the full benchmark →

Quick Start

Requirements: Node.js 18.17 or newer with npx on PATH, plus Docker running for the default local Qdrant and Ollama stack.

For one recommended setup path per host and short practical scenarios, use the quick guides. This README has the other installation paths and full configuration.

Quick install guidance for Claude Code, VS Code, and Cursor:

MCP hosts with a JSON mcpServers object can use this complete configuration:

{
  "mcpServers": {
    "socraticode": {
      "command": "npx",
      "args": ["-y", "--prefer-online", "socraticode@latest"]
    }
  }
}

Configuration schemas are host-specific. Continue, VS Code, Zed, OpenCode, Gemini CLI, and Cline have dedicated examples in Plugins and host integrations.

Keeping SocratiCode up to date

SocratiCode has two independent update paths. The MCP engine is the socraticode package published to npm. Every npm-backed configuration below uses npx -y --prefer-online socraticode@latest, which checks npm for the current latest release whenever the MCP server starts. A running server cannot replace itself, and a newly published version can only be downloaded while the npm registry is reachable, so restart or reconnect the server after a release.

Native plugins and extensions also contain skills, instructions, manifests, or UI files. Update those through the host as shown below, then start a new session so the new plugin files load. Direct MCP installations contain only the engine and do not install SocratiCode's plugin skills.
