example-server — MCP server by stbenjam/claude-marketplace-template

example-server

example-server is an MCP server for Claude Code from stbenjam/claude-marketplace-template. Its token cost is not measured, scanned A, original, MIT.

A local tool connection that gives an agent read and write access to specified folders on the computer. It runs through the Model Context Protocol, a standard way for agents to call external tools.

In plain words

What is it for?: Use it to read and update files in the configured data directory, with the required configuration supplied through an environment variable.
Why use it?: It lets the agent work with approved local files without granting access to the entire filesystem.

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: listed in a Claude config.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the example-plugin plugin — 1 skill, 1 command, 1 agent, 1 MCP server shipped together

Good fit Use it to read and update files in the configured data directory, with the required configuration supplied through an environment variable.

Security

Grade A, and why

example-server 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 4d 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.
