Hosted MCP
Hosted MCP server for business AI that lives in Prostir
Use a hosted MCP server to connect a Prostir agent to a compatible AI client. Keep its knowledge, tools and access rules hosted while you work in a familiar chat.
For the usual MCP path, model-token cost to the Agent creator is $0: the customer's AI client supplies the model under that customer's subscription and limits.

What is getting in the way
Sharing a useful agent should not require every user to maintain its source files or run a server.
What changes
A published agent with its own hosted address, authorized tools and an MCP endpoint you can verify in supported clients.

How Prostir gets you there
Build the useful agent
Describe the business job in Builder and configure the sources and supported tools it needs.
Choose exact access
Keep the agent private or grant the intended people access. Configure the appropriate OAuth or approved machine access.
Connect your client
Add the hosted MCP endpoint to a compatible client and complete sign-in. Test its tools and permissions before sharing instructions.

What you can verify
- Every published Agent exposes MCP on its own canonical HTTPS typed host.
- New Agents start OAuth-protected, with exact email or domain grants and explicit scoped API keys as an alternative.
- The published Agent remains the runtime owner for sessions, knowledge, tools, access, billing, and telemetry behind the endpoint.
A good fit if
- You need a remote MCP endpoint for an Agent without operating a local server and tunnel.
- You can test against the exact MCP client, account tier, connector policy, and transport you plan to support.
Not the right fit if
- You need a generic arbitrary MCP server unrelated to a Prostir Agent product.
- You need a promise that every client, account, connector, or review policy accepts the endpoint without qualification.
Questions before you decide
Will it work in every MCP client automatically?
The endpoint uses the published MCP contract, but each client can impose its own account, connector, authentication, certificate, or review requirements. Test the exact destination before making a universal claim.
Can I expose it anonymously?
Only through the separate explicit Anonymous choice for an eligible free Agent after risk confirmation. Private OAuth access is the default.
Who pays for model tokens, and what do they cost the Agent creator?
For the usual MCP path, model-token cost to the Agent creator is $0. When a customer uses the Agent through a supported MCP connector in ChatGPT or Claude, the model runs in that customer's AI environment under the customer's subscription and limits. The creator pays for the Prostir plan, not those model tokens. AI Credits are needed only when the creator separately chooses a Prostir-hosted model run, such as a supported channel or widget. BYOK is optional and bills the creator's own provider account. Paid external tools remain separate.
How do I give a team or client access?
Share your published Agent at https://{slug}.ai.prostir.build with its MCP path /mcp; recipients do not need to install or maintain source files. Allow specific users or domains through OAuth, or give an approved integration an API key with limited permissions and an expiry date. You can revoke access.
