Set up this server

01 / Choose your client

02 / Before you connect

The maintainer declares that no authentication is required.

Install the runtime required by the project and make it available to your client.

Project instructions

Use names from the project instructions, separated by commas. Enter names only, never secret values.

03 / Add the configuration

Source: generated from public install instructions

claude mcp add --transport stdio 'mcptoon' -- 'uvx' 'mcptoon' 'demo-server'

Run in your terminal after replacing any placeholders.

04 / Check it in your client

Open your client’s MCP settings and confirm the server connects and lists its tools. A copied configuration does not confirm a working connection.

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.

NVIDIA SkillSpector v2.11.0, MCPVault MCP-server policy. Scanned yesterday @ 768d5cc.

  • Talks to external services5 places

    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 bulk1 places

    Copies or enumerates the whole environment, which can include keys meant for other tools.

  • Runs shell commands8 places

    Spawns processes on your machine. Expected for command, browser and build tools.

  • Loads code at runtime2 places

    Uses eval, dynamic imports or encoded payloads, which static review cannot fully follow.

  • Passes model output on without checks2 places

    Model output reaches HTML, SQL or a shell without validation.

  • Runs unpinned packages at runtime42 places

    Executes npx or uvx without a version, so a compromised upstream release would run.

Not detected: sends conversation content outward, reads or writes other agents' configuration, accesses credential files, uses elevated privileges, installs itself to run later, matches a known malicious pattern.

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.
