mcp-crawl4ai-rag: Instructions file for Claude Code

CLAUDE.md

mcp-crawl4ai-rag CLAUDE.md is an instructions file for Claude Code from rbj2000/mcp-crawl4ai-rag. It costs 3,830 tokens per session, scanned A, original, MIT.

A set of project instructions for an MCP server that crawls websites and stores their content for search and retrieval. It supports several AI providers, vector databases, and local or Docker-based setups.

In plain words
What is it for?
Developing or running web crawling and retrieval systems, configuring text or image search, choosing databases and AI providers, and setting up local or production deployments.
Why use it?
It explains how to configure the server for different storage, AI, privacy, and deployment needs instead of relying on one fixed setup.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-crawl4ai-rag CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a Model Context Protocol (MCP) server that integrates Crawl4AI with multiple vector databases and AI providers for advanced web crawling and RAG (Retrieval Augmented Generation) capabilities. The server enables AI agents and coding assistants to crawl websites, store content in vector databases, and perform intelligent document retrieval with optional AI hallucination detection using Neo4j knowledge graphs.

Key Features:

  • Multi-AI Provider Support: OpenAI, Ollama, vLLM, and hybrid configurations
  • Multi-Modal RAG: Text, image, and vision model support via vLLM
  • Multiple Vector Databases: Supabase, SQLite, Neo4j, Pinecone, Weaviate
  • Flexible Deployment: Docker orchestration with various provider combinations
  • Cost Optimization: Mix providers (e.g., vLLM embeddings + OpenAI LLM)
  • Privacy Options: Fully local deployment with Ollama
  • Enterprise Ready: Production deployment with monitoring and health checks

Development Commands

Docker (Recommended)

Quick Start with Provider Selection:

# OpenAI + Supabase (Production)
docker compose --profile supabase up -d

# Ollama + SQLite (Local Development)
docker compose --profile ollama-sqlite up -d

# Hybrid OpenAI/Ollama + Supabase (Cost-Optimized)
docker compose --profile hybrid up -d

# Full Ollama Stack with Neo4j and Monitoring
docker compose --profile ollama-full up -d

Custom Build:

# Build with specific providers
docker build -t mcp/crawl4ai-rag \
  --build-arg AI_PROVIDER=ollama \
  --build-arg VECTOR_DB_PROVIDER=sqlite .

# Run with environment file
docker run --env-file .env -p 8051:8051 mcp/crawl4ai-rag

Direct Python Development

# Install dependencies
uv pip install -e .
crawl4ai-setup

# Configure AI provider (examples)
export AI_PROVIDER=openai  # or ollama, vllm, mixed
export OPENAI_API_KEY=your_key

# OR for Ollama
export AI_PROVIDER=ollama
export OLLAMA_BASE_URL=http://localhost:11434

# OR for vLLM
export AI_PROVIDER=vllm
export VLLM_BASE_URL=https://your-vllm-endpoint.com/v1
export VLLM_API_KEY=your_vllm_api_key

# Run the MCP server
uv run src/crawl4ai_mcp.py

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
