Overview

AI-generated overview

0n3 (0nmcp) exposes 125 services and 1,851 endpoints from your connected apps as AI tools, behind one sign-in and one vault, with receipts.

What you can do
  • Connect your apps through a single 0n3 sign-in and hosted vault.
  • Let an assistant call endpoints across 125 services (1,851 endpoints) as tools.
  • Use a hosted vault listing your connected services, reachable from a local stdio install.
  • Keep a receipt trail of the calls made through the runtime.
  • No individual tools are listed in the manifest, so exact operations are not documented here.
When to use it
Worth considering when you want one assistant connection to reach many of your existing apps and services instead of installing a separate MCP server for each, and you are comfortable routing those calls through a hosted vault.
Requirements
Either the remote endpoint at 0n3.app with OAuth (Authorization header) or the local npm package 0nmcp over stdio. A 0n token is needed: ON3_TOKEN for stdio (optional, used to list your hosted vault) and an Authorization bearer token for the remote endpoint. A 0n3 account and network access.
Before you install
Requires a 0n token (ON3_TOKEN or the Authorization bearer header) that grants access to your connected apps; treat it as a secret. Calls run against real services through a hosted vault, so actions may read or change data in those apps, and request details pass through the 0n3 service. Review which services are connected before use.

Installation

In SourceWeft

  1. Open 0n3 — the 0n runtime (0nmcp 5) in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.0nork%2F0nMCP/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
