File contents

MCP Configuration Validator

Validate the project's MCP setup for correctness and completeness.

Validation Steps

1. Check Configuration Files

File	Scope	What lives here
`.mcp.json` (project root)	Project	`mcpServers` — the server definitions, written by `claude mcp add --scope project`
`.claude/settings.json`	Project	Toggles only: `enableAllProjectMcpServers`, `enabledMcpjsonServers`
`~/.claude.json`	User	User-scope `mcpServers`, available across all projects

The source of truth for project servers is .mcp.json at the project root. Read mcpServers from there — .claude/settings.json never holds server definitions, only approval toggles.

2. Validate Structure

.mcp.json is valid JSON (no trailing commas)
mcpServers object exists in .mcp.json
Project servers are approved via .claude/settings.json: either enableAllProjectMcpServers: true, or each server named in enabledMcpjsonServers

3. Validate Each MCP

command is valid
args properly formatted
env variables set

4. Check Essential MCPs

MCP	Required?
memory	Recommended
filesystem	Optional
github	If .git exists

5. Security Check

No hardcoded secrets
Sensitive values use env vars
