Security profile
Exposure: Broad
Reaches into the environment, credential files or other agents' configuration.
What this server can reach, from a static read of the shipped code. Nothing was executed and nothing here is a verdict: a browser tool has to run commands and an API wrapper has to call its API. Decide what fits your setup.
Detected
- Talks to external services
Makes outbound requests. The hosts are listed so you can see where data goes.
api.github.com, api.githubcopilot.com, api.star-history.com
- Reads environment variables in bulk
Copies or enumerates the whole environment, which can include keys meant for other tools.
- Runs shell commands
Spawns processes on your machine. Expected for command, browser and build tools.
- Loads code at runtime
Uses eval, dynamic imports or encoded payloads, which static review cannot fully follow.
- Passes model output on without checks
Model output reaches HTML, SQL or a shell without validation.
- Runs unpinned packages at runtime
Executes npx or uvx without a version, so a compromised upstream release would run.
Dependencies with known advisories
None found in the lockfiles and manifests checked against OSV.dev.
Left out of the profile
44 pattern matches in documentation, configuration or CI files were recorded but are not part of the profile, because they do not run when the server does. The owner dashboard lists them.

FAQ
Questions about Mcptoon MCP Server
- How do I connect Mcptoon MCP Server to Claude?
- Run `claude mcp add mcptoon -- uvx mcptoon demo-server` in Claude Code, or add the same command and arguments under mcpServers in Cursor's mcp.json or Claude Desktop's claude_desktop_config.json, then restart the client. The blocks above are ready to paste.
- Is Mcptoon MCP Server free?
- The listed licence is Apache-2.0. Check the upstream terms for permitted use and commercial requirements; a public repository does not by itself mean the software is free or open source. Connected APIs and hosted services may have separate charges.
- What can Mcptoon MCP Server do?
- MCPVault has not yet recorded the tool list for Mcptoon MCP Server; it is captured when the server passes a live MCP handshake. The description above is what the project publishes.
