Frequently Asked Questions about tooluniverse-claude-code-plugin

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I install the ToolUniverse plugin for Claude Code?▼

Run claude plugin marketplace add mims-harvard/ToolUniverse, then claude plugin install tooluniverse@tooluniverse, and restart Claude Code. The MCP server auto-starts via uvx tooluniverse on first use with about a 30 second cold start.

How do I enable auto-update for a Claude Code plugin marketplace?▼

Edit ~/.claude/plugins/known_marketplaces.json and set autoUpdate to true for the tooluniverse entry, or use /plugin → Marketplaces → tooluniverse → Enable auto-update. This is per-machine state that cannot be shipped in the plugin manifest.

Why is my Claude Code MCP server not starting?▼

Test the package directly with uvx tooluniverse in a terminal. If that fails, verify uv is installed and your Python version is 3.10 or higher, then restart Claude Code since the first launch downloads the package.

Why does uvx run an old version of tooluniverse after updating?▼

A global uv tool install shadows the plugin's uvx resolution. Run uv tool list to check, then uv tool uninstall tooluniverse and restart Claude Code so uvx resolves the latest published PyPI version.

Do ToolUniverse tools require API keys?▼

Most tools work without keys. For enhanced access, add keys such as NCBI_API_KEY, NVIDIA_API_KEY, or ONCOKB_API_TOKEN to the env block of the plugin's .mcp.json file.

Do I need to remove globally installed ToolUniverse skills after installing the plugin?▼

Yes. Global copies installed via tooluniverse-install-skills or manual copy interfere with the plugin's skill routing. Remove them with rm -rf ~/.claude/skills/tooluniverse-* before using the plugin.
