validate-mcp skillA

validate-mcp is agent-read markdown (skill) from pdugan20/claudelint: Validates MCP server configuration files (.mcp.json). Use when user asks to "check my .mcp.json", "why isn't my MCP working", ".mcp.json errors", "validate MCP servers", or "MCP connection failed". Validates transport types (stdio, sse, http, websocket), server names, and environment variables..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add pdugan20/claudelint/validate-mcp@v1.0.0
Exact content
mdr add pdugan20/claudelint/validate-mcp@sha256:f56b3d89e8b247de

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
