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:

  1. Queries Stripe for overdue invoices
  2. Formats a summary
  3. Posts to Slack
  4. Sends the email
  5. Reports back

You describe the outcome. AI figures out the path.

CRM Snapshots — Deploy Entire Configurations

"Deploy a full CRM snapshot with a 12-stage sales pipeline,
 all lead tags, custom values, and 18 workflow definitions"

One tool call. Everything deployed:

{
  "pipeline": {
    "name": "Sales Pipeline",
    "stages": ["001. New Lead", "002. Attempt to Contact", "003. Engaged",
               "004. Appointment Set", "005. Appointment Showed", "006. Proposal Sent"]
  },
  "tags": ["New Lead", "FB Lead", "Hot Lead", "Booked Appointment", "No Show"],
  "custom_values": {
    "calendar_link": "https://calendly.com/yourlink",
    "support_email": "support@yourco.com",
    "welcome_sms": "Hey {{contact.first_name}}, welcome aboard!"
  },
  "workflows": [
    {
      "id": "001a",

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.

See CONTRIBUTING.md for the full guide.
