mcp-scorecard

mcp-scorecard is a skill for Claude Code, Codex from davidmosiah/mcp-scorecard. It costs 21 tokens per session (141 once invoked), scanned A, original, MIT.

A guide for using MCP Scorecard, a tool that checks whether an MCP server is ready for AI agents. It explains the MCP and command-line ways to run an audit.

In plain words
What is it for?
Use it when auditing an MCP server from an already connected MCP tool or from the command line.
Why use it?
It helps an agent choose the correct interface and pass the server target in the expected format. It avoids duplicating the same package client.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-scorecard 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 7d 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.

What it actually says

MCP Scorecard — skill or MCP

Same package, two doors. The MCP tool is audit and requires target.

npx -y mcp-scorecard call audit --json '{"target":"./dist/index.js"}'

If MCP tools are already connected, call audit with { "target": "..." }. Do not invent mutation flags. MCP: mcp-scorecard serve. CLI subject form mcp-scorecard <path> --json is the same audit once a target is known.

Changes

What this file has done since we first saw it

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.
