The Universal AI API Orchestrator

Connect your apps. Say what you want. AI does the rest.

850 tools. 53 services. Zero configuration. One natural language interface.

Website · Quick Start · Services · 850 Tools · .0n Standard · Unlocks · Community

v2.3.0 — 850 tools across 53 services in 23 categories. 1,142 total capabilities. New in v2.3: 5 new services (Cloudflare, GoDaddy, n8n, Pabbly, Make), Resend expanded (3→67 endpoints), ACTION_ALIASES conversion layer for intuitive .0n workflow authoring, connection auto-enrichment (locationId, pipelineId injected from .0n files), and enhanced API validation (CRM, Anthropic, Vercel). 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 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 via Gmail to john@client.com"

"Create a Jira 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"],

    "welcome_sms": "Hey {{contact.first_name}}, welcome aboard!"
  }
}

All Tools

Universal Tools (7)

CRM Tools (245)

The deepest CRM integration available in any MCP server. 245 tools across 12 modules — every endpoint, every parameter, full CRUD.

850 total tools. Universal orchestration (576 catalog tools across 53 services) + the most comprehensive CRM integration in the MCP ecosystem (245 dedicated tools) + Vault (4 tools) + Vault Containers (8 tools) + Business Deed Transfer (6 tools) + Engine (6 tools) + App Builder (5 tools).

Every CRM tool is data-driven — defined as configuration, not code. Adding new endpoints takes minutes, not hours. See CONTRIBUTING.md.

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...

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

├── 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

0nVault Container Security (Patent Pending)

• AES-256-GCM encryption for all container layers

• Argon2id double-encryption for credential layer (memory-hard, side-channel resistant)

• Ed25519 digital signatures for container authenticity

• Seal of Truth — SHA3-256 content-addressed integrity verification

• X25519 ECDH multi-party escrow — up to 8 parties with per-layer access matrix

• Binary .0nv format — magic bytes 0x304E5350, tamper-evident structure

• Transfer registry — replay prevention with chain of custody tracking

• Machine-bound vault — PBKDF2-SHA512 (100K iterations) + hardware fingerprint binding

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

Configuration

Environment Variables

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.
