MCP

Bring your Cannon Studio workflow to your agent.

The Cannon Studio MCP server gives AI agents a public, source-backed way to answer prospect questions about workflows, pricing, model availability, comparisons, and the developer API. Public tools are read-only; authenticated tools use OAuth account linking or developer API keys.

Connection URLs

Use the Streamable HTTP endpoint for ChatGPT Developer Mode, Codex, OpenAI Responses API remote MCP, MCP Inspector, and other compatible clients.

This serverless endpoint supports request/response Streamable HTTP over POST. Plain browser GET requests return endpoint metadata, HEAD requests return 204, and standalone SSE GET requests with Accept: text/event-stream return the protocol-defined 405 because long-lived standalone SSE is not offered. Use the health URL below for web-style probes.

Dynamic OAuth client registration supports loopback callbacks for local apps. Hosted clients must use an exact callback URL approved by Cannon Studio; arbitrary remote callback domains are rejected.

Public read-only tools

These tools answer from public Cannon Studio pages, guides, assistant knowledge, model availability, developer docs, and public offering data. Checkout links are first-party Cannon Studio URLs only; they do not charge the user or create Stripe sessions from MCP.

Authenticated tools

These tools use OAuth account linking or a developer API key and can touch account/request state. Billable creation requires confirmation plus a max credit cap. No MCP cancellation tool is exposed.

Creator Flow workspace & project overviews

Connect with workspace:read to explore accessible projects and your worlds/assets. Workspace:write enables draft creation, editing, and confirmed deletion. Existing connections must reconnect to approve these additional permissions; developer generation API keys do not grant workspace access.

Start with list_creator_flow_projects, inspect a project, then use export_creator_flow_project. Save the embedded HTML resource as a file to explore chapters, scenes, shot readiness, images, videos, and references. The file also includes search, print/PDF, and a JSON download. Snapshots are private, point-in-time exports; linked media requires network access and may expire.

In the Creator Flow composer, choose Download project overview. Draft CRUD does not start media generation or spend credits. Delete tools preview impact first; execution requires dry_run=false, confirmed=true, and the matching title. Shared projects follow project roles; only owners can delete projects.

Privacy and registry setup

Public tools do not read private workspaces, projects, billing records, user assets, payment details, or API keys. Offering and checkout-link tools do not grant credits, create Stripe sessions, or process payment inside MCP. To publish with HTTP/domain authentication, set MCP_REGISTRY_AUTH_RECORD to the official registry record and verify it at /.well-known/mcp-registry-auth.
