550 tools. 26 services. Zero configuration. One natural language interface.
Quick Start · Services · 550 Tools · .0n Standard · Unlocks · Community · Contributing
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.
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?
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.
# 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.
npx 0nmcpOr install globally:
npm install -g 0nmcpAdd 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.

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.
The orchestrator uses keyword matching to route tasks to the right service. Less intelligent but still functional for straightforward single-service requests.
| 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 |
0nMCP implements the .0n Standard — a universal configuration format for AI orchestration.

| Component | What It Does |
|---|---|
| Service Catalog | Defines all 26 services — their base URLs, endpoints, auth patterns, and capabilities |
| Connection Manager | Stores credentials as .0n files in ~/.0n/connections/ per the .0n standard |
| Orchestrator | The brain — parses natural language, plans multi-step execution, calls APIs, chains data |
| CRM Modules | 245 tools across 12 modules — data-driven, every tool is config not code |
| Rate Limiter | Per-service rate limits with automatic retry and backoff |
| Webhook Handler | Receive and process external events from connected services |
| Execution History | Logs every task to ~/.0n/history/ as JSONL — full audit trail |
| TypeScript Defs | Full type coverage for all exports, connections, workflows, and tools |
- 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.0nfiles, 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.
| Variable | Required | Description |
|---|---|---|
ANTHROPIC_API_KEY |
No | Enables AI-powered multi-step planning. Keyword matching without it. |
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}}"
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",
}),
},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.

Our position: 0nMCP is and always will be free and open source. We built this because we believe AI orchestration is infrastructure — it should be accessible to every developer, not locked behind enterprise paywalls or monthly subscriptions.
If you find someone selling this tool, know that it's free right here. Always has been, always will be. The entire codebase is open, auditable, and community-maintained.
We chose MIT for maximum freedom. Use it in your projects, your products, your startups. But if you build something great with it, give back to the community that made it possible. That's the deal.
Trademarks: The names "0nMCP", "0nORK", and ".0n Standard" are trademarks of RocketOpp. The MIT license grants rights to the software, not to the trademarks. You may not use these names to promote derivative products without permission.
We want 0nMCP to be the open standard for AI-powered API orchestration.
