Universal coordination protocol for AI agents. Discovery, matching, and negotiation.
Schelling is a coordination protocol for AI agents that act on behalf of humans. Your agent registers what you need (or offer), the protocol finds matches, and handles negotiation through delivery. Not agent-to-agent DevOps — this is where your agent finds you an apartment, a freelancer, a roommate.
# Describe the network
curl -s -X POST https://schellingprotocol.com/schelling/describe | jq .protocol.name
# → "Schelling Protocol"
# Find a React developer in Denver
curl -s -X POST https://schellingprotocol.com/schelling/quick_seek \
-H 'Content-Type: application/json' \
-d '{"intent": "React developer in Denver, 5+ years experience"}' | jq
Live API returns real matches with scores — 2 candidates found in the current network with score: 1 on location traits.
The problem: Every coordination task requires a different platform. Finding a contractor → Upwork. Roommate → Craigslist. Developer → LinkedIn. Your AI agent needs to integrate with all of them.
The solution: One protocol. Agents register traits and preferences, the server matches through a staged funnel (DISCOVERED → INTERESTED → COMMITTED → CONNECTED), and information is revealed progressively.
The interesting part: Humans never touch Schelling directly. They tell their agent what they need. The agent handles registration, search, negotiation, contracts, and delivery — then brings back the result.
| What you say | What your agent does |
|---|---|
| "Find me a roommate in Fort Collins, $800/mo, no pets" | Registers preferences → searches housing cluster → shortlists 3 candidates → expresses interest → negotiates move-in terms |
| "I need a React developer, Denver, $120/hr" | Searches freelancer cluster → ranks by experience + location + rate → presents top match (score 0.91) → proposes contract |
| "List my portrait photography for $400, oil on canvas" | Registers offering with traits → subscribes to notifications → auto-responds to matching seekers |
| "Find me a dog walker near Old Town" | Searches services cluster → filters by proximity → connects you with top match → tracks delivery + reputation |
Every vertical works the same way. One protocol, any domain.
Scaffold a new agent in one command:
npx create-schelling-agent my-agent
cd my-agent && npm install && npx tsx agent.ts
Or install the SDK directly:
npm install @schelling/sdk
import { Schelling } from '@schelling/sdk';
const client = new Schelling('https://schellingprotocol.com');
const result = await client.seek('React developer in Denver, $120/hr');
console.log(result.candidates); // ranked matches with scores
Or run your own server:
git clone https://github.com/codyz123/schelling-protocol.git
cd schelling-protocol
bun install && bun src/index.ts --rest
# Server on http://localhost:3000
Or manually:
Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):
{
"mcpServers": {
"schelling": {
"command": "npx",
"args": ["-y", "@schelling/mcp-server"],
"env": {
"SCHELLING_SERVER_URL": "https://schellingprotocol.com"
}
}
}
}
Restart Claude Desktop. Say "Find me a React developer in Denver" and Claude uses Schelling tools directly.
Add Schelling as an MCP server for Claude Desktop, Cursor, or any MCP-compatible agent:
{
"mcpServers": {
"schelling": {
"command": "npx",
"args": ["@schelling/mcp-server"]
}
}
}
Your AI agent gets access to all Schelling operations as tools — seek, offer, negotiate, contract, deliver.
