Workflowy: MCP server, setup and security
Workflowy is an open-source MCP server that lets an AI agent create and update nodes and perform regex replacements with dry runs. Its repository has 72 stars and its last commit is from August 14, 2026 and it is licensed under MIT.
What Workflowy does
According to its repository: “Create, update, complete nodes, search & replace with regex and dry run, usage reports, transforms”
An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Workflowy is listed under Code execution, a category of 32 servers in the directory, where it ranks #18 by stars.
Topics declared by the repository: claude, cli, golang, model-context-protocol-server, outline, productivity.
Installing and connecting Workflowy
Distribution modes declared in the official MCP registry:
- Docker (OCI) image
Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Go.
The registry lists one secret variable to provide (API key, access token). Keep them in the client's environment variables, never in a shared file or a repository.
Security: what to check
An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.
Points found for Workflowy:
- System access: the Code execution category gives the agent control over files, a terminal, code or a browser. A booby-trapped instruction in content the agent reads (prompt injection) can then turn into an action.
- Secrets: the server acts with your credentials. Create a dedicated key with minimum rights and an expiry date.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on November 23, 2025, the mholzen/workflowy repository has 72 stars and 7 forks, with 8 open issues. It has more stars than 60% of the servers in the directory. Last change 2 months ago. Version published in the registry: 0.8.1 (February 10, 2026).
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
