The Problem
You have Stripe for payments. SendGrid for email. Slack for messaging. Airtable for data. A CRM for contacts.
Today, to automate across them, you need:
Zapier ($50+/month) — and build complex zaps
n8n/Make — and learn their visual builders
Custom code — and maintain API integrations forever
What if you could just... talk to them?

The Solution
You: "Invoice john@acme.com for $500 and notify #sales on Slack when it's sent"0nMCP figures out the rest:
Step 1: Found John Smith (john@acme.com) in Stripe
Step 2: Created invoice INV-0042 for $500.00
Step 3: Posted to #sales: "New invoice sent to John Smith for $500"
Done. 3 steps. 2 services. 1.2 seconds.No workflows. No mapping. No code. Just results.
Watch It Work
# In Claude Desktop after setup:
You: "Connect to Stripe with key sk_live_xxx"
AI: Connected to Stripe (8 capabilities available)
You: "Connect to Slack with bot token xoxb-xxx"
AI: Connected to Slack (4 capabilities available)
You: "Get my Stripe balance and post it to #finance"
AI: Your Stripe balance is $12,450.00. Posted to #finance.That's it. No configuration files. No workflow builders. No decisions about which API to use.
Installation
One Command
npx 0nmcpOr install globally:
npm install -g 0nmcpConfigure Claude Desktop
Add to ~/Library/Application Support/Claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"0nmcp": {
"command": "npx",
"args": ["0nmcp"],
"env": {
"ANTHROPIC_API_KEY": "sk-ant-..."
}
}
}
}
ANTHROPIC_API_KEYis optional. It enables AI-powered multi-step task planning. Without it, 0nMCP still works using keyword-based routing.
Restart Claude Desktop. Start talking.

└─────────────────┘ └──────────────────┘ └─────────────────┘With ANTHROPIC_API_KEY (AI Mode)
Claude analyzes your task, inspects connected services and their capabilities, creates a multi-step execution plan, runs every API call in order, passes data between steps, and summarizes the results.
Without API Key (Keyword Mode)
The orchestrator uses keyword matching to route tasks to the right service. Less intelligent but still functional for straightforward single-service requests.
Why Not Just Use...
0nMCP | Zapier | Custom Code | |
Setup time | 2 minutes | 30+ min per zap | Hours/days |
Learning curve | None (natural language) | Medium (visual builder) | High (APIs, auth) |
Multi-step tasks | Just describe it | Build complex zaps | Write orchestration logic |
Cost | Free + your API keys | $20-$100+/month | Your time |
Flexibility | Say what you want | Triggers/actions only | Unlimited but complex |
Maintenance | Zero | Update broken zaps | Fix API changes |
Open source | Yes (MIT) | No | Depends |

Security
Local execution — MCP server runs on your machine, not in the cloud
Direct API calls — Requests go straight to each service, not through a proxy
Your credentials — Stored locally at
~/.0nmcp/connections.json, never sent anywhereAnthropic key — Only used for task planning (never passed to external services)
Open source — Audit every line yourself
Configuration
Environment Variables
Variable | Required | Description |
| No | Enables AI-powered multi-step planning. Keyword matching without it. |
Credential Storage
Connections stored in plain text at ~/.0nmcp/connections.json. For production:
Use a secrets manager
Encrypt the connections file
Use environment variables for credentials
For Developers
Adding a New Service
Drop a definition into catalog.js:
your_service: {
name: "Your Service",
type: "category",
description: "What it does",
baseUrl: "https://api.yourservice.com",
authType: "api_key",
credentialKeys: ["apiKey"],
capabilities: [
{ name: "do_thing", actions: ["create", "list"], description: "Does the thing" },
],
endpoints: {
do_thing: { method: "POST", path: "/things", body: { name: "" } },
list_things: { method: "GET", path: "/things" },
},
authHeader: (creds) => ({
"Authorization": `Bearer ${creds.apiKey}`,
"Content-Type": "application/json",
}),
},Add keyword triggers to orchestrator.js. Submit a PR. Done.
See CONTRIBUTING.md for the full guide.
