Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "afferens": {
      "command": "npx",
      "args": [
        "-y",
        "@afferens/mcp-server"
      ]
    }
  }
}

Run this in your terminal

claude mcp add afferens -- npx -y @afferens/mcp-server

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "afferens": {
      "command": "npx",
      "args": [
        "-y",
        "@afferens/mcp-server"

Common questions

Is Afferens MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@afferens/mcp-server

MCP server for Afferens - real-time physical perception for AI agents.

Use it from local MCP clients over stdio or remote/hosted clients over streamable HTTP. It gives any MCP-compatible AI assistant live sensor data: object detections, positions, sounds, environmental readings, chemical traces, and node health.

Tools

Tool	Auth	Description
`afferens_demo`	None	Live perception data across all 6 modalities. Free, no key needed.
`afferens_perceive`	API key	Query live events by modality with filtering and limits.
`afferens_verify`	API key	Fetch the feed twice and return a proof bundle with headers, age, and a freshness verdict.

Modalities: VISION / SPATIAL / ACOUSTIC / ENVIRONMENTAL / MOLECULAR / INTEROCEPTION

Quick Start

Free tier: 10,000 tokens, no card required. Get your key at afferens.com.

Local MCP Clients

claude mcp add afferens -- npx -y @afferens/mcp-server

Then set your key:

claude mcp add afferens -e AFFERENS_API_KEY=YOUR_KEY -- npx -y @afferens/mcp-server

This stdio setup works for Claude Code, Claude Desktop, Cursor, and Windsurf.

Remote MCP Clients

For hosted or browser-based clients, run Afferens in HTTP mode and point the client at the /mcp endpoint:

AFFERENS_TRANSPORT=http AFFERENS_PORT=8790 AFFERENS_API_KEY=YOUR_KEY node dist/index.js

Then register the endpoint:

"afferens": { "url": "http://127.0.0.1:8790/mcp", "bearer_token_env_var": "AFFERENS_API_KEY" } }

Claude Desktop / Cursor / Windsurf

Add to your MCP config file:

"mcpServers": { "afferens": { "command": "npx", "args": ["-y", "@afferens/mcp-server"], "env": { "AFFERENS_API_KEY": "YOUR_KEY" } } } }

Config file locations:

Claude Desktop (Mac): ~/Library/Application Support/Claude/claude_desktop_config.json
Claude Desktop (Windows): %APPDATA%\Claude\claude_desktop_config.json
Cursor: .cursor/mcp.json in your project root
Windsurf: ~/.codeium/windsurf/mcp_config.json

Try it without a key

"mcpServers": { "afferens": { "command": "npx", "args": ["-y", "@afferens/mcp-server"] } } }

Call afferens_demo - no API key needed.

Usage

Once connected, your AI agent can call:

afferens_perceive({ modality: "VISION", limit: 5 })

Returns structured perception events your agent can reason over and act on.

For demo verification:

afferens_verify({ modality: "VISION", limit: 3, wait_ms: 2000 })

Returns two raw snapshots plus headers, age, and a hash check so you can show whether the feed is live, stale, or unchanged.
