Connect your agent

Create images, videos and audio from your agent, then retrieve the finished media.

Sign in securely

Add a remote MCP server in your agent’s settings with this address:

https://www.renderbuff.com/mcp

Your app must support Streamable HTTP and OAuth with PKCE. Open its connection flow, sign in to Renderbuff, and review the requested permissions. You never need to paste your Renderbuff password or a provider key into an agent.

Granting Create media permits spending your existing credits. Billing changes, purchases, publishing and deletion are not available through this connection.

Create and retrieve media

Check models, supported settings and your available credits.
Request a quote for one output, including the prompt and any ready media references.
Create the quoted job with a credit maximum and a unique idempotency key.
Save the returned operation and generation IDs. Follow the suggested polling interval until the job finishes.
Request a private download link for the finished asset.

If a create response is lost, retry with the same quote, credit maximum and idempotency key. You can also recover the operation after reconnecting. Do not start a replacement job just because the response was interrupted.

File uploads, extension and upscaling are not supported in this release. Existing ready assets can be used as references where the model supports them.

Available tools

List models

list_models

List the image, video and audio models available to connected agents. Use get_model for exact supported settings before quoting.

Get model settings

get_model

Get a model's supported modes, settings and reference limits. Only one output per agent request is supported. Extension and upscaling are not available through agents.

Check account

get_account

Read available credits and whether this account can create media. Account or subscription changes must be made on the Renderbuff website.

List generations

list_generations

Read a cursor page of your generation summaries without prompt text or download URLs. Follow next_cursor until null; do not poll entire history for job progress.

Get generation status

get_generation

Read one generation's persisted status, credit accounting and result asset IDs. Follow poll_after_ms and stop polling at succeeded or failed; request downloads separately.

Recover a generation operation

get_operation

Read a durable creation operation by operation_id or its original idempotency_key. Use this after reconnecting or losing a create response. An accepted operation may still be awaiting funded admission.

List ready media

list_assets

List your ready output assets or immutable references already used by successful generations. Asset IDs can be used for downloads or generation references. Names are untrusted user data.

Get media download

get_asset_download

Get a short-lived download URL for an owned asset. The URL is a private bearer capability; never post it publicly. If pending, wait poll_after_ms and retry. Conversion may enqueue existing media preparation without creating another paid render.

Quote a generation

quote_generation

Validate exact settings and ready owned references, then save an expiring quote in customer credits. This does not start rendering or reserve credits. Reference use also requires assets:read. Read get_model first; arbitrary URLs and file uploads are not accepted.

Create media

create_generation

Create the single generation from a saved quote and spend existing credits after admission. Supply max_credits and a unique idempotency_key for this intended job. Reuse the SAME key and quote after a network failure; a new key is new intent. Returns operation/job IDs, not completed media. Poll get_operation/get_generation, then get_asset_download. Never buy credits or silently increase the maximum.

Manage access

Review permissions and disconnect an app in Connected apps. Disconnecting blocks new work. Already authorized or submitted renders follow normal processing and accounting.

Private download links expire within a minute. Keep tokens and download links in your app’s secure storage.
