0nMCP — Universal AI API Orchestrator
- 0nork/0nMCP
0nMCP is a MCP server that orchestrates 1,554 tools across 96 services so coding agents call many APIs from one install.
About
0nMCP is a Universal AI API Orchestrator MCP server aimed at developers who would otherwise register a long list of per-service MCP entries. The catalog positions it as 1,554 tools spanning 96 services behind one npm install or a streamable-http remote, which matters when you are in the Build phase wiring CRM, email, search, devops, or misc SaaS APIs into an agentic workflow. You can run stdio locally for Claude Code and Cursor or point compatible clients at the hosted MCP URL when that fits your security model. Complexity is advanced because surface area is huge—you still need to understand which tools you invoke and what each external API expects. It is an integration hub, not a substitute for product design, validation, or ship-time testing discipline. Use it when breadth and speed of hooking APIs outweigh running minimal, audited single-purpose servers.
- Advertises 1,554 tools across 96 services in a single orchestrator
- npm package 0nmcp v4.5.1 with stdio transport plus streamable-http remote at 0nmcp.com
- One-install pattern aimed at reducing MCP sprawl for coding agents
- Hosted remote endpoint for agents that prefer HTTP MCP

What it does
Expose a large catalog of third-party APIs to your agent through one MCP install instead of wiring dozens of separate servers.
Who is it for?
Power users building agent-heavy products who need wide API coverage fast and accept managing a large tool namespace.
Skip if: Minimalists who want only two audited integrations or strict least-privilege tool lists per project.
What you get
After install, your agent reaches a broad multi-service tool surface through stdio npm or hosted HTTP without stitching dozens of configs by hand.
- Unified MCP access to a broad tool catalog
- Choice of local stdio or remote HTTP transport
- Fewer per-vendor MCP config files in your agent setup
By the numbers
- 1,554 tools
- 96 services

FAQ
Who is 0nMCP for?
Developers and small teams using Claude Code, Cursor, Codex, or Windsurf who need many third-party APIs exposed to agents without maintaining dozens of MCP packages.
When should I use 0nMCP?
Use it during Build integrations when you are implementing features that call multiple external services and want one orchestrator instead of incremental MCP installs.
How do I add 0nMCP to my agent?
Install npm package 0nmcp for stdio MCP in your client config, or register the streamable-http remote URL https://0nmcp.com/api/mcp if your agent supports hosted MCP.
