@anuraghq/neuron-mcp-server

Neuron Context Engine MCP server — structured memory for Cursor, Claude Desktop, Antigravity, and any MCP client.

npm: @anuraghq/[email protected]

One-command install

Get your API key from neuron-azure.vercel.app → MCP Setup.

npx @anuraghq/neuron-mcp-server init --api-key nrn_your_key_here

Or run interactively — paste your key when prompted:

npx @anuraghq/neuron-mcp-server init

Restart your MCP client(s). Works with Cursor, Claude Desktop, and any MCP host.

Install targets (default: Cursor + Claude)

# Both Cursor (~/.cursor/mcp.json) and Claude Desktop
npx @anuraghq/neuron-mcp-server init --api-key nrn_your_key_here

# Cursor only
npx @anuraghq/neuron-mcp-server init --cursor --api-key nrn_your_key_here

# Claude Desktop only (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json)
npx @anuraghq/neuron-mcp-server init --claude --api-key nrn_your_key_here

# Print JSON for any other MCP client
npx @anuraghq/neuron-mcp-server init --stdout --api-key nrn_your_key_here

With NEURON_API_KEY, the MCP server proxies all tool calls to the hosted Neuron API. Supabase and Groq credentials stay on the server — customers only need one key.
