For Developers

One MCP Server. One Developer API.

Connect Codex, Claude, and Cursor to your OPC workspace through Model Context Protocol — or build custom integrations on top of our scoped REST API.

MCP Server

Plug any MCP-compatible AI client into OPC. Works out of the box with Claude Desktop, Codex CLI, Cursor, and Cline.

  • Streamable HTTP transport at /api/mcp
  • Local stdio bridge on npm — zero install friction
  • Per-token scopes — read or write, module by module
  • Every tool call logged for audit
$ npx -y @tsa-ai/opc-mcp-server
View on npm

Developer API

A scoped REST API across every module — drive OPC from your own backend, scripts, or third-party automation.

  • Endpoints for contacts, products, inventory, sales orders, quotations, accounting...
  • Bearer auth with Personal Access Tokens — SHA-256 hashed at rest
  • Granular scopes like contacts.read · products.write
  • Revoke any token instantly from Settings → Developer
$ curl -H "Authorization: Bearer opc_pat_..." \
  https://www.myopc.io/api/contacts
Manage API Keys

Quickstart

Three steps to connect your AI assistant to OPC.

1

Create a token

Issue a Personal Access Token from Settings → Developer and pick the scopes you need.

2

Wire up the bridge

Add @tsa-ai/opc-mcp-server to your MCP client config — Claude Desktop, Codex CLI, or Cursor.

3

Start chatting

Your AI client now sees your OPC data through MCP — type a request, it runs the tool.
