Install

How do I install the Cofferdock MCP server?

Cofferdock is a hosted endpoint at https://api.cofferdock.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 26 exposed · ~3,120 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the Cofferdock MCP server?

Cofferdock is an MCP server listed in the public MCP registry as com.cofferdock/cofferdock. Real files for AI assistants: HTML to image/PDF, screenshots, QR, charts, PDF tools, validators. This page covers its hosted endpoint (https://api.cofferdock.com/mcp).

Is the Cofferdock MCP server safe to use?

Cofferdock scores 38 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Cofferdock MCP server expose?

Cofferdock exposes 26 tools: get_status, html_to_image, html_to_pdf, screenshot_url, generate_qr, and 21 more. Their descriptions and schemas cost roughly 3,120 tokens of context every time the server is loaded.

Does the Cofferdock MCP server require authentication?

Yes. Cofferdock asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the Cofferdock MCP server still maintained?

Cofferdock is still listed as active in the MCP registry. We last reached this channel on 3 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
