How to Set Up and Use Context+
Context+ (@neuledge/context) is a semantic intelligence MCP server that transforms large codebases into searchable, hierarchical feature graphs by combining RAG retrieval, Tree-sitter AST parsing across 43 languages, and spectral clustering. It exposes tools for deep code discovery, blast radius analysis, static analysis, and a persistent knowledge graph with memory nodes and typed relation edges — giving AI coding assistants persistent, accurate context beyond a single conversation window. It is designed for developers and AI agents working on large or unfamiliar repositories where exhaustive file-by-file reading would exceed context limits.
Prerequisites
- Node.js 18+ and npm installed
- An MCP-compatible client such as Claude Desktop or Claude Code
- Ollama running locally with the nomic-embed-text model (for local embeddings), OR an OpenAI-compatible API key
- A codebase directory accessible on the local filesystem
- No cloud account required for local embedding mode
Run with npx (no install required)
The @neuledge/context package can be run directly via npx without a global install. This is the recommended way to get started.
npx -y @neuledge/contextGenerate the MCP configuration for Claude
Use the built-in init command to automatically produce the correct configuration snippet for Claude Desktop or Claude Code.
npx -y @neuledge/context init claudeSet embedding provider environment variables
Choose your embedding backend. Ollama runs locally with no API costs; the OpenAI provider uses the API but may give higher quality embeddings.
# Local (Ollama):
export CONTEXTPLUS_EMBED_PROVIDER=ollama
export OLLAMA_EMBED_MODEL=nomic-embed-text
# Cloud (OpenAI-compatible):
export CONTEXTPLUS_EMBED_PROVIDER=openai
export CONTEXTPLUS_OPENAI_API_KEY=sk-...
export CONTEXTPLUS_OPENAI_EMBED_MODEL=text-embedding-3-small
export CONTEXTPLUS_OPENAI_BASE_URL=https://api.openai.com/v1Add to Claude Desktop configuration
Paste the generated configuration into claude_desktop_config.json, ensuring the environment variables for your chosen embedding backend are included in the env block.
Restart your MCP client
Restart Claude Desktop or Claude Code so it picks up the new server. On first activation, Context+ will index the target codebase.
Context+ Examples
Client configuration
Add this to claude_desktop_config.json. Adjust environment variables to match your embedding provider choice.
{
"mcpServers": {
"context": {
"command": "npx",
"args": ["-y", "@neuledge/context"],
"env": {
"CONTEXTPLUS_EMBED_PROVIDER": "ollama",
"OLLAMA_EMBED_MODEL": "nomic-embed-text"
}
}
}
}Prompts to try
After the server has indexed your codebase, use these prompts to explore and understand it.
- "Show me the context tree for the top-level features of this repository"
- "Semantically search for code related to rate limiting"
- "What is the blast radius of changing the database schema for the users table?"
- "Add a memory node noting that the auth module uses JWT with RS256 signing"
- "Retrieve all memory nodes related to API security across this project"
- "List available restore points before I start refactoring"Troubleshooting Context+
Tools return empty results or indexing seems to have not run
On first use, Context+ must index the codebase which can take several minutes for large repos. Check terminal output for indexing progress. If embeddings are failing silently, verify the CONTEXTPLUS_EMBED_PROVIDER variable is set and the provider is reachable.
Ollama embedding fails with connection refused
Ensure Ollama is running ('ollama serve') and the model is downloaded ('ollama pull nomic-embed-text'). Ollama defaults to http://127.0.0.1:11434 — check with 'curl http://127.0.0.1:11434/api/tags'.
npx -y @neuledge/context fails to resolve the package
Check npm registry access: 'npm view @neuledge/context'. If the package is not found, try installing globally: 'npm install -g @neuledge/context' and run 'context' directly. Verify Node.js 18+ with 'node --version'.
