A remote connection that lets coding agents work with Whimsical, a visual workspace for diagrams and collaborative boards.

The supplied information only identifies the remote MCP connection; it does not say which Whimsical actions are available.

It can provide an agent connection to Whimsical instead of requiring the agent to work only with text or local files.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/WhimsicalCode/mcp-server-guide

Made for: Claude Code.

Or install whimsical, the plugin that ships this one along with the rest of its 1 MCP server.

Security

Grade A, and why

whimsical scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
