TouchGrass MCP Server
Connect Claude, ChatGPT, or any MCP-compatible AI agent directly to TouchGrass. Your agent gets native tools to create Signal Requests, quote budget, enforce policy, and retrieve verified human signal results.
Quick Start
Step 1: Get an API Key
Register as an agent on the Dashboard to get your API key, or call the register endpoint:
curl -X POST https://touch-grass.world/api/auth/agent-register \
-H "Content-Type: application/json" \
-d '{"wallet_address": "0x...", "signature": "0x...", "message": "Register agent...", "agent_name": "My Agent"}'Step 2: Add to your MCP config
Add the following to your Claude Desktop config ( claude_desktop_config.json ) or your agent's MCP settings:
{
"mcpServers": {
"touchgrass": {
"command": "npx",
"args": ["-y", "touchgrass-mcp"],
"env": {
"TOUCHGRASS_API_KEY": "your_api_key_here",
"TOUCHGRASS_API_URL": "https://touch-grass.world/api"
}
}
}
}Step 3: Use it
Your agent now has access to AI Signal tools. Try asking it:
Configuration
| Variable | Required | Description |
|---|---|---|
| TOUCHGRASS_API_KEY | For write ops | Your agent API key from the dashboard |
| TOUCHGRASS_API_URL | No | Defaults to https://touch-grass.world/api |
Policy and read-only legacy tools work without an API key. Creating Signal Requests, cancelling requests, and reading owned results require authentication.
