Audit one mcp.json for what an agent config gives away — inline API keys, unpinned npx launches, plaintext remote servers, shell wrappers, auto-approved tools, whole-machine filesystem roots — with line numbers. The shipped sample config _fixtures/dirty.mcp.json (33 lines, five servers) returns 14 findings, 8 of them blocking.

Install

npx @readystack/mcp-config-audit file

Node 18+. The same 18 rules as the VS Code extension, from a terminal or CI.

Free

Audit one mcp.json against all 18 rules and get every inline credential, unpinned launch and over-broad grant named with its line number and its replacement. The extension ships a sample config, _fixtures/dirty.mcp.json, 33 lines and five servers, which returns 14 findings, 8 of them blocking, and its corrected twin _fixtures/clean.mcp.json, which returns zero.
--rules lists every rule

With a licence ($29 once)

Audit every agent config in a repository and in the user-scope locations for VS Code, Cursor, Claude Desktop and Windsurf in one pass, fail CI with a non-zero exit code on any blocker, and export a dated evidence report of file, rule and line.

@readystack/mcp-config-audit --dir ./templates --report html --out report.html

Freelance application-security engineers commonly bill $100-$200 an hour; a single review hour costs more than three licences, and the config changes every time somebody adds a server.

Use from an AI agent (MCP)

Claude Code · Cursor · Windsurf · any MCP client - add to your MCP config:

{ "mcpServers": { "mcp-config-audit": { "command": "npx", "args": ["-y", "@readystack/mcp-config-audit", "--mcp"] } } }

Tools: check_text and check_file (free) · check_dir (licence; the full sweep is free for 7 days). The agent gets every finding with the line number.
