API Key Case vs HAL
A side-by-side look at the API Key Case and HAL MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
A
API Key CaseDeveloper ToolsLocal MCP tools for secret status and guarded deployment. Values never reach the agent.36FairAuth: no auth requiredVerdict: choose API Key Case for developer tools work; choose HAL for developer tools as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
AChoose API Key Case when
- You need dedicated capabilities in the Developer Tools domain.
- Its auth model fits you: No auth required.
Choose HAL when
- You need dedicated capabilities in the Developer Tools domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You have the keys it needs:
HAL_SWAGGER_FILE, HAL_API_BASE_URL, HAL_SECRET_API_KEY, HAL_WHITELIST_URLS, HAL_BLACKLIST_URLS, HAL_ALLOW_MICROSOFT. - You want tools like
http-get, http-post, http-put.

Ready-to-paste client configs
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
