v1.7.0 — 550 tools across 26 services in 13 categories. Now with the .0n Conversion Engine (portable AI Brain bundles), Vault (machine-bound encrypted credential storage), Application Engine (build + distribute .0n apps), Workflow Runtime + HTTP Server, and a CLI with named runs. See what's new.

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 [email protected] for $500 and notify #sales on Slack when it's sent"

0nMCP figures out the rest:

Step 1: Found John Smith ([email protected]) 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 [email protected]: Meeting moved to 3pm"

"Create a Stripe customer for [email protected]"

"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 via Gmail to [email protected]"

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

"Look up [email protected] 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"

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 | | Tools available | 550 | Varies | Whatever you build |

---

The .0n Standard

0nMCP implements the .0n Standard — a universal configuration format for AI orchestration.

~/.0n/
├── config.json               # Global settings
├── connections/              # Service credentials as .0n files
│   ├── stripe.0n
│   ├── slack.0n
│   └── sendgrid.0n
├── workflows/                # Saved automation definitions
│   └── invoice-notify.0n
├── snapshots/                # System state captures
│   └── crm-setup.0n
├── history/                  # Execution logs (JSONL by date)
│   └── 2026-02-06.jsonl
└── cache/

Every connection is stored as a .0n file with a standard header:

{
  "$0n": {
    "type": "connection",
    "version": "1.0.0",
    "name": "Production Stripe"
  },
  "service": "stripe",
  "auth": {
    "type": "api_key",
    "credentials": { "api_key": "sk_live_..." }
  }
}

Every task execution is logged to ~/.0n/history/ as JSONL — full audit trail of what ran, when, and how.

---

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 in ~/.0n/connections/ as .0n files, never sent anywhere
• Anthropic key — Only used for task planning (never passed to external services)
• Rate limiting — Built-in per-service rate limits prevent accidental API abuse
• Execution history — Full audit trail in ~/.0n/history/
• Open source — Audit every line yourself

See SECURITY.md for our security policy and how to report vulnerabilities.

---

Configuration

Environment Variables

| Variable | Required | Description | |----------|----------|-------------| | ANTHROPIC_API_KEY | No | Enables AI-powered multi-step planning. Keyword matching without it. |

Credential Storage

Connections stored as .0n files in ~/.0n/connections/. For production:

• Use a secrets manager
• Enable encryption via ~/.0n/config.json
• Use environment variables: "api_key": "{{env.STRIPE_KEY}}"

---

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",
  }),
},

Adding CRM Endpoints

Even easier — just add a config object to the relevant module:

{
  name: "crm_do_thing",
  description: "Does the thing in the CRM",
  method: "POST",
  path: "/things/:thingId",
  params: {
    thingId: { type: "string", description: "Thing ID", required: true, in: "path" },
    name:    { type: "string", description: "Thing name", required: true, in: "body" },
  },
  body: ["name"],
}

The tool factory handles registration, validation, API calls, error handling — everything. See CONTRIBUTING.md for the full guide.
