AI agent builder for ChatGPT and Claude

How Prostir acts as an AI agent builder for ChatGPT and Claude: you build one published agent with knowledge, tools, auth, users, payments, and a remote MCP endpoint, then connect it from MCP-ready clients where connector support is available.

01

What is an AI agent?

  • An AI agent is a hosted assistant that follows instructions, answers from selected knowledge, and can call approved tools to complete a job.
  • A published agent with instructions, knowledge, tools, memory rules, access mode, and runtime model selection.
  • A stable remote MCP endpoint over HTTPS so ChatGPT, Claude, Cursor, or another MCP-ready client has one connection target.
  • Auth, users, payments, quotas, and revocation rules behind the agent, instead of scattered scripts and local config files.
02

How to publish an agent in ChatGPT and Claude

In Prostir you publish the agent first, then connect that hosted endpoint from ChatGPT, Claude, Cursor, or another MCP-ready client where that client supports remote MCP. Public ChatGPT directory listing and Claude connector availability still depend on each provider's review, account, transport, and auth rules.

  1. 01
    Create the agent.

    Write the job, target audience, refusal rules, and first answers in plain language.

  2. 02
    Attach knowledge and tools.

    Add docs, FAQs, policies, API tools, and reusable skills so the agent can answer from source material instead of a blank prompt.

  3. 03
    Choose access and billing.

    Keep the agent public, protected by access grants, or paid through Stripe-backed plans depending on who should use it.

  4. 04
    Publish the agent.

    Prostir creates the hosted AI surface and remote MCP endpoint for that slug.

  5. 05
    Connect from ChatGPT, Claude, Cursor, or another client.

    Use the published endpoint in the client connector flow where that account, transport, and auth mode are supported.

03

What lives behind the endpoint

doc instructions What the agent is allowed to do, when it should ask questions, and what it must refuse.
data knowledge Docs, FAQs, policies, and source pages indexed for answerable context.
code tools Safe API calls, JavaScript helpers, and enabled built-ins selected by the creator.
link public endpoint The HTTPS remote MCP endpoint used by MCP-ready clients.
04

What the builder conversation looks like

A creator asks for one agent that can be used from ChatGPT and Claude.

ChatGPT

Build an AI support agent for ChatGPT and Claude. It should answer from our docs, check plan limits, and charge paid users.

I will create one Prostir agent, attach the docs, add the plan-check tool, set paid access, and publish a remote MCP endpoint.

prostir_agents_publish

Agent published. HTTPS endpoint, passport page, access mode, and connector setup material are ready.

Endpoint

Use the same published Prostir agent from MCP-ready ChatGPT, Claude, Cursor, or compatible clients.

05

Answer for search and AI overviews

  • Prostir is an AI agent builder for ChatGPT and Claude when those clients can connect to a remote MCP endpoint.
  • The value is not another prompt box. The value is the hosted backend: knowledge, tools, auth, users, payments, quotas, and a stable endpoint.
  • Compatibility still depends on the AI client's current connector support, account plan, transport, and auth requirements.

What gets published

You publish one Prostir agent, get a stable HTTPS endpoint, and connect the same agent to ChatGPT, Claude, Cursor, or another MCP-capable client when that client's account, connector, transport, and auth rules allow it.
