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 0nmcp

Or install globally:

npm install -g 0nmcp

Configure 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_KEY is optional. It enables AI-powered multi-step task planning. Without it, 0nMCP still works using keyword-based routing.

Restart Claude Desktop. Start talking.

Examples

Simple Tasks

"Send an email to sarah@example.com: Meeting moved to 3pm"

"Create a Stripe customer for mike@startup.io"

"Post to #engineering on Slack: Deploy complete!"

"Send SMS to +1555123456: Your order shipped"

"What's my Stripe balance?"

"Search Notion for project roadmap"

Multi-Step

"Create a Stripe invoice for $1000, then email the link to john@client.com"

"Create a GitHub issue for the login bug, then post it to #bugs on Slack"

"Look up sarah@example.com in my CRM and send her a follow-up email"

Complex Orchestration

"Check if we have any overdue invoices in Stripe. If so, send a summary
 to #finance on Slack and email the finance team."

The AI:

Queries Stripe for overdue invoices
Formats a summary
Posts to Slack
Sends the email
Reports back

You describe the outcome. AI figures out the path.

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

Component	What It Does
Service Catalog	Defines all 17 services — their base URLs, endpoints, auth patterns, and capabilities
Connection Manager	Stores and retrieves credentials locally at `~/.0nmcp/connections.json`
Orchestrator	The brain — parses natural language, plans multi-step execution, calls APIs, chains data
Universal Tools	MCP interface: `execute`, `connect_service`, `api_call`, etc.
CRM Tools	Direct access: pipelines, tags, custom values, workflows, full snapshot deploy

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 anywhere
Anthropic key — Only used for task planning (never passed to external services)
Open source — Audit every line yourself

Configuration

Environment Variables

Variable	Required	Description
`ANTHROPIC_API_KEY`	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.
