What's the difference between an MCP and an API for company formation?

An API is a raw HTTP interface you wire into your own code. An MCP server exposes typed, self-describing tools that an AI agent can discover and call natively — with structured inputs/outputs and human-approval gates. For agent-native workflows, MCP; for custom backends, an API.

Which should I use to form a company for my AI agent?

If an AI agent is the one doing the work, use a hosted MCP — the agent can discover and call the tools directly. If you're building a custom backend or product, a REST API gives you lower-level control. OffshoreProz is MCP-native and also offers a simple REST register endpoint.

Is OffshoreProz an MCP or an API?

OffshoreProz Agent Company is a hosted MCP server (Streamable HTTP) your agent connects to via Smithery or by URL, with a small REST endpoint to issue an API key. Free agent_company_diagnostic tool, no key.

MCP vs API for company formation

If you want a company formed programmatically — especially by an AI agent — you'll choose between a raw API and an MCP server. They're not the same layer. Here's the difference, and when to use each.

In one line: an API is a raw interface you wire into your own code; an MCP server is a tool layer an AI agent calls natively — discoverable, typed, with human-approval gates. For agent-driven workflows, use MCP. For a custom backend, use an API. OffshoreProz is MCP-native (with a small REST endpoint for keys).

What an API gives you

A REST/HTTP API is the lowest-level option: endpoints, request/response schemas, an API key. You write the integration, handle auth, parse responses, and build any agent logic, retries, and approval steps yourself. Maximum control — and maximum work. Great when you are building a product or backend around it.

What an MCP server adds

The Model Context Protocol is a standard that lets an AI agent discover and call tools directly. Instead of hand-wiring HTTP, the agent sees a set of self-describing tools (name, typed inputs/outputs), calls them in its own loop, and the server can mark sensitive tools as requiring human approval. It's the difference between "here's an endpoint, go integrate" and "here's a capability your agent can already use".

Side-by-side

Dimension	Raw API	MCP server
Who calls it	Your code	The AI agent, natively
Tool discovery	You read docs & wire it	Self-describing, auto-discovered
Inputs / outputs	You parse JSON	Typed, structured tools
Human-approval gates	Build yourself	Built into the tool layer
Setup effort	High (full integration)	Low (connect by URL)
Best for	Custom backends/products	Agent-native workflows

So which for company formation?

An AI agent is doing the work → MCP. The agent discovers the tools and runs the flow (diagnose → scope → form → status), with approval on the sensitive steps.
You're building a custom product/backend → an API gives lower-level control (e.g., a formation API you wrap yourself).
Both? Use the MCP for the agent and the REST endpoint where you need raw calls.

How OffshoreProz does it

OffshoreProz Agent Company is a hosted MCP server (Streamable HTTP). Connect via the Smithery listing or point your client at https://server.smithery.ai/offshoreproz/agent-company/mcp, then call agent_company_diagnostic (free, no key). The formation tools are gated by an API key you get instantly via a small REST endpoint: curl -X POST https://splendid-eagerness-production-9b85.up.railway.app/register. So you get MCP-native for the agent and a raw endpoint where you want it.
