MrScraper for OpenCode

MrScraper connects OpenCode to a hosted MCP server for retrieving public web pages as HTML, Markdown, or screenshots, web search, and account usage. The plugin also includes three focused skills that help OpenCode choose the right workflow and preserve raw page content.

The same package works in OpenCode 2 and OpenCode 1.

What this plugin adds

• An MCP server named mrscraper that points at the hosted Streamable HTTP endpoint https://mcp.mrscraper.com/mcp.
• OAuth 2.1 sign-in handled by OpenCode; no credential is stored in this package.
• The mrscraper, mrscraper-fetch, and mrscraper-serp skills.
• A retrieve-first workflow that keeps raw page responses available for analysis, verification, and follow-up transformations.

If your configuration already defines a mrscraper MCP server, the plugin keeps your entry and only adds the skills. It also leaves any skill with the same name that you already have in place.

Requirements

• OpenCode 2 (verified with 2.0.26), or OpenCode 1.18.29 or later (verified with 1.18.29 and 1.19.0). On older OpenCode 1 releases, pin @mrscraper/opencode@0.1.0.
• A MrScraper account.
• Permission to access and process the target content.

Install

OpenCode 2

opencode plugin add @mrscraper/opencode

This adds the package to plugins in your global configuration. To enable it for one project instead, add it to that project's opencode.jsonc:

{
  "$schema": "https://opencode.ai/config.json",
  "plugins": ["@mrscraper/opencode"]
}

OpenCode 1

opencode plugin @mrscraper/opencode --global

Or add the package to the plugin list in ~/.config/opencode/opencode.json (all projects) or a project's opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["@mrscraper/opencode"]
}

OpenCode installs npm plugins when it starts and caches them.

Sign in

opencode mcp auth mrscraper

In OpenCode 2 you can also run /mcps in a session, select mrscraper, and sign in there. OpenCode opens the MrScraper consent page in your browser, registers its own OAuth client, and stores the tokens outside your project configuration. Never paste OAuth tokens or API keys into chat.

Check the connection:

opencode mcp list

mrscraper shows needs authentication before sign-in and connected afterwards.

On a machine without a local browser, use an API key instead (next section). OpenCode 1 waits for the browser on http://127.0.0.1:19876/mcp/oauth/callback, so you can also forward that port, for example ssh -L 19876:127.0.0.1:19876 <host>.

Use an API key instead of OAuth

Create a key at app.mrscraper.com/api-tokens, export it as MRSCRAPER_API_KEY in the environment that starts OpenCode, and define the server yourself.

OpenCode 2 (opencode.jsonc):

{
  "$schema": "https://opencode.ai/config.json",
  "plugins": ["@mrscraper/opencode"],
  "mcp": {
    "servers": {
      "mrscraper": {
        "type": "remote",
        "url": "https://mcp.mrscraper.com/mcp",
        "oauth": false,
        "headers": { "Authorization": "Bearer {env:MRSCRAPER_API_KEY}" }
      }
    }
  }
}

OpenCode 1 (opencode.json):

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["@mrscraper/opencode"],
  "mcp": {
    "mrscraper": {
      "type": "remote",
      "url": "https://mcp.mrscraper.com/mcp",
      "oauth": false,
      "headers": {
        "Authorization": "Bearer {env:MRSCRAPER_API_KEY}"
      }
    }
  }
}

OpenCode substitutes {env:MRSCRAPER_API_KEY} when it loads the configuration, so the key stays out of the file. In OpenCode 2 the substitution happens in the background service, so the variable must be set where the service starts; after setting it, run opencode service restart from that shell. An API key carries your full account authority; OAuth scopes do not apply to it.

Try it

Fetch https://www.scrapethissite.com/pages/simple/ and summarize the page.

The server provides these tools. OpenCode 1 shows them as mrscraper_<tool>; OpenCode 2 reaches MCP tools through Code Mode by default.

Tool	Purpose
scraperAPI	Retrieve a known page as HTML, Markdown, a screenshot, or a combination.
webSearch	Discover public pages through web search.
status	Inspect subscription status, token usage, and remaining tokens.

Retrieve-first routing

When a public URL is already known, the skills direct OpenCode to retrieve it with scraperAPI first and treat the raw response as the source of truth. The agent can read, summarize, compare, or derive structured output locally without losing details.

For roughly 100 known pages with a shared layout, the agent can retrieve pages concurrently, retain every raw response, and apply one reusable local extractor.

Data and permissions

The plugin sends MCP tool inputs, including target URLs and search queries, to MrScraper's hosted service. Page responses and tool results are then available to OpenCode and its model provider for the requested task. Use it only with public or otherwise authorized content, and follow the target site's requirements.

Review MrScraper's MCP documentation, Privacy Policy, Acceptable Use Policy, and Terms of Use before use.

Update or remove

OpenCode 2 checks unpinned npm plugins for updates without installing them. Update or remove the plugin with:

opencode plugin update @mrscraper/opencode
opencode plugin remove @mrscraper/opencode

In OpenCode 1, an unpinned entry stays on the version OpenCode first cached. To control updates, pin a version and change it when you upgrade:

{
  "plugin": ["@mrscraper/opencode@0.3.0"]
}

To remove it from OpenCode 1, delete the entry from plugin. In either version, remove the stored OAuth tokens afterwards:

opencode mcp logout mrscraper

You can also revoke access under Connected applications in your MrScraper account.

Development

index.ts        default export with an OpenCode 2 `setup()` and an OpenCode 1
                `server()`; both register the MCP server and the skills
skills/         MCP-oriented skills, copied verbatim from
                mrscraper-com/mrscraper-claude-plugin (plugins/mrscraper/skills)

npm install
npm run check
npm pack --dry-run

Test a local checkout in both majors before a release. In OpenCode 2, add the checkout's absolute path to plugins, then run opencode mcp list and opencode api skill.list. In OpenCode 1, add it to plugin, then run opencode mcp list and opencode debug skill. Record user-visible changes in CHANGELOG.md and follow PUBLISHING.md for releases.
