Git vs HAL
A side-by-side look at the Git and HAL MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Git for other tools and integrations work as a local process; 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?
Choose Git when
- You need dedicated capabilities in the Other Tools and Integrations domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You want tools like
create_entities, create_relations, add_observations.
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.

Frequently asked questions
Git is categorized under Other Tools and Integrations and uses a local stdio subprocess. HAL belongs to Developer Tools and uses a local stdio subprocess. Pick Git for other tools and integrations work and HAL for developer tools.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Git is listed as free. Auth: no auth required. HAL is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add git and hal as separate keys in the same mcpServers object, and your assistant will call tools from either one.
