OpenCode does not provide one built-in MCP tool that generates video, PDFs, and images. It connects to external MCP servers; the server or provider supplies the actual generation tools. The OpenCode documentation reviewed for this guide explains how to connect those servers, but does not identify a single verified server that creates all three formats. Choose and verify a server’s tools before following format-specific generation instructions.
There is also an important distinction between asking an external tool to create a file and attaching an existing file for a model to inspect. In OpenCode’s documented V2 prompt path, supported image formats can be provided as model inputs, but PDF and video binaries are not directly included. A PDF page can be exported to PNG when the goal is to show its contents to a model.
What OpenCode MCP does—and does not do
OpenCode is the agent environment in this workflow. It connects to an MCP server and makes that server’s exposed tools available to the agent, subject to configuration and permissions. The external server or its underlying provider determines whether the available operation generates an image, renders a PDF, creates video, or does something else.
That means “generate media with OpenCode” is not one universal command. The exact tool name, arguments, credentials, output location, supported formats, cost, and limits depend on the particular server and provider. The official OpenCode material covered here establishes the connection mechanism, not a media-generation recipe for a named server. Don’t assume a tool exists because an MCP server connects successfully.

- Ordinary file conversion: a local or external program converts a file, such as exporting a PDF page to PNG. That conversion is not automatically an MCP capability.
How to connect an MCP server to OpenCode
OpenCode supports local MCP servers launched as commands over stdio and remote MCP servers using Streamable HTTP. Configuration examples in the versioned OpenCode documentation place server entries under mcp.servers. A local entry can specify a command, working directory, and environment variables; a remote entry uses an absolute URL and can include headers or OAuth configuration.
Local server: command over stdio
For a local server, configure the command OpenCode should start and, if needed, its working directory and environment. The command and arguments are specific to the server you choose, so use that server’s own current installation documentation rather than copying an unverified package name or launch command. Keep API credentials in environment variables instead of writing secrets into a project configuration file.
Remote server: Streamable HTTP
For a remote server, configure its absolute MCP URL. OpenCode’s documentation says remote OAuth is enabled by default unless disabled. Its OAuth flow can use authorization-server discovery, PKCE, token refresh, and dynamic client registration when the server supports those mechanisms. If the remote server instead authenticates with an API key or another header credential, the documented pattern is to disable OAuth and supply the secret through an environment variable.
Use the current versioned OpenCode configuration reference for exact syntax: protocol and timeout options can vary by version, and the documentation describes startup, catalog, and execution timeouts as well as per-server overrides. Avoid assuming an older example’s settings are current.
Confirm that the tools are actually available
After connecting, inspect the tools exposed by the server and check that the relevant tools are permitted. OpenCode can expose tools directly or through its default Code Mode; permissions can hide or deny tools without disconnecting the server. Tool names are prefixed with the server name and normalized. MCP prompts, if provided, appear as named commands. A concise server name makes the resulting tool names easier to recognize.
- Pick an MCP server whose current documentation explicitly describes the media operation you need.
- Configure it locally over stdio or remotely over Streamable HTTP, following that server’s authentication requirements.
- Start or reload OpenCode, then inspect the exposed tools and permissions.
- Read the selected tool’s argument schema and output behavior before invoking it. Confirm whether it returns a file, a URL, text, or a job identifier.
- Run a small test using a non-sensitive prompt or input, then verify the resulting file and format outside the chat.
How do I generate images with an OpenCode MCP server?
Connect an image-generation MCP server or a server that exposes an image provider, then call the tool it actually exposes. OpenCode’s connection support alone does not identify a universal image tool or establish a prompt syntax. In particular, do not treat the ability to attach PNG or JPEG images for inspection as evidence that OpenCode can generate them.

Before relying on a server for image creation, verify its current documentation for:
- The exact tool name and required arguments, including prompt and any dimensions or style settings it documents.
- Whether the result is returned as image bytes, saved to a path, or made available through a URL or asynchronous job.
- The formats it actually returns and any size, resolution, content, or provider limits.
- Whether prompts and images are processed locally or sent to a remote provider, and what credentials and usage charges apply.
Once the tool is configured, invoke it through OpenCode using the schema shown for that server. Save or retrieve its result according to the server’s documented output path. If you want the model to inspect the generated image afterward, attach a supported image file separately; successful generation does not guarantee that the output is within the model provider’s input limits.

Can OpenCode generate videos?
It can only do so in a workflow where a connected external MCP server or provider exposes a video-generation operation. The OpenCode integration documentation covered here does not verify a specific video server, tool name, model, output format, duration limit, or price. Consequently, there is no evidence-based generic video-generation command to give for OpenCode.
For a server you are considering, check that its own current documentation explicitly covers video generation—not merely video analysis, playback, or file handling. Verify how it returns completed videos, whether generation is synchronous or job-based, and what provider limits and credentials apply. If the operation runs asynchronously, use the server’s documented polling or callback procedure rather than assuming the first tool response contains a finished video.
Can I create a PDF from OpenCode?
PDF creation likewise depends on an external tool or ordinary document-generation software. The OpenCode MCP connection feature does not itself establish a PDF-creation tool, and the reviewed official OpenCode sources do not provide a verified PDF-generation server or recipe. Confirm whether the server you select creates a PDF from text, a web page, or another source, and check how it saves or returns the file.
Keep PDF creation distinct from capturing a web page as a PDF. A screenshot service can capture a page and return a PDF, but that does not make it a general-purpose tool for composing arbitrary documents. For example, ScreenshotNeo is a website screenshot API and MCP server; its documented capability includes PDF capture. Use the service appropriate to the task, and verify that the specific output you need is supported.

Can OpenCode read an attached PDF or video?
Not as a PDF or video binary in the documented V2 prompt path. That path makes UTF-8 text, directory listings, and PNG, JPEG, GIF, and WebP images visible to the model. PDF, video, audio, and other unsupported binary files are not included in the documented model request. Renaming a file or changing its declared media type does not make its binary contents readable.
To show PDF content
Export the relevant page or pages to PNG, then attach the images. This lets the model inspect the rendered page image, but it is not equivalent to giving the model the original PDF’s searchable text or structure. For a long document, select the pages relevant to the question rather than assuming an entire PDF will fit within model or client limits.
To show a video
The documented attachment path does not include video binaries in the model request. If the task is visual inspection, extract representative frames as supported image files and provide those instead. If the task depends on dialogue or sound, extract a transcript or other text representation separately; audio binaries are also outside the documented supported inputs.
Image limits and provider constraints
OpenCode’s documented image-normalization defaults are automatic resizing enabled, a maximum width of 2,000 pixels, a maximum height of 2,000 pixels, and a maximum Base64-encoded size of 5,242,880 bytes. These are configurable positive-integer settings, not guarantees that every model provider will accept an image. Provider and model rules for format, dimensions, file count, and size still apply.

With resizing enabled, OpenCode preserves aspect ratio and may encode the smaller output as PNG or JPEG. If resizing is disabled and configured limits are exceeded, processing fails. The desktop file picker documents a 20 MiB total-selection limit; other interfaces may have lower client-side limits. These details describe the documented V2 behavior, not a universal limit across every client or provider.

The server connects, but no generation tool appears
Check the server’s own tool list and connection logs, then inspect OpenCode permissions and tool exposure settings. A connected server does not guarantee that a particular tool is available, enabled, or named as expected. Confirm the server is the generation-capable product or configuration you intended to connect.
Authentication fails
Confirm whether the server expects OAuth or an API key/header. Remote OAuth is enabled by default in the documented configuration unless disabled; for key-based authentication, follow the server’s requirements and keep the key in an environment variable. Check that the variable is present in the environment OpenCode actually starts with, not only in an unrelated shell.
The server starts slowly or a tool times out
Check the server process, network reachability, and the relevant startup, catalog, or execution timeout. OpenCode documents timeout settings and per-server overrides, but the correct value depends on the server’s startup and task duration. Increase a timeout only when the server is expected to take longer; it will not fix a dead process, unreachable endpoint, or provider-side failure.

An image exceeds a size limit
With automatic resizing enabled, OpenCode may reduce an image while preserving its aspect ratio. If resizing is disabled, an image that exceeds configured limits fails processing. Reduce the source dimensions or adjust the documented positive-integer settings carefully, then check that the provider accepts the resulting image as well.
Automation and reliability notes
OpenCode’s serve command runs a headless HTTP server and exposes an OpenAPI 3.1 specification. Its documented endpoints include configuration and provider listing, MCP status, and dynamic MCP addition. Those are OpenCode automation and management APIs; they are not the external media-generation tools themselves.
For production workflows, treat media creation and subsequent model inspection as separate stages. Record which external server performed each operation, check whether its output is complete before passing it onward, and handle provider limits and errors at the stage where they occur. Do not infer billing, retry behavior, uptime, or output guarantees unless the chosen server or provider documents them.
Frequently Asked Questions
Does installing OpenCode automatically give me image, PDF, or video generation?
No. OpenCode connects to MCP servers; the connected server or provider must expose the relevant generation tool.
Can I attach a PDF after converting it to an image?
Yes. A PDF page exported as PNG is a supported image input in the documented V2 prompt path, subject to client and provider limits.
