Here are some of the more common use cases for ToolHive:

<table>
<tr valign="top">
<td><strong>Developers.</strong> Run MCP servers with more security and more (token) savings</td>
<td><strong>Platform Engineers.</strong> Run MCP on your existing Kubernetes infrastructure</td>
<td><strong>Enterprises.</strong> Self-host MCP servers and stay in control of your data</td>
</tr>
<tr valign="top">
<td>Connect Claude Code, Cursor, GitHub Copilot, or your preferred client to MCP servers with a single click or command.<br><br>
ToolHive wraps every MCP server in an isolated container with a minimal permission file (no local credentials) and uses semantic tool search to reduce your token usage by up to 85%.</td>
<td>Put an end to shadow MCP use by your developers, and give your security team the audit logs and configurable identity enforcement they require.<br><br>
ToolHive includes a Kubernetes operator, so you can declare policies, integrate with your IdP and observability stack, emit OTel traces, and more … all with familiar tools and patterns.</td>
<td>Most MCP solutions are SaaS, but your compliance requirements prohibit sensitive info from being processed by SaaS providers.<br><br>
ToolHive is the exception that allows you to self-host your MCP registry, gateway, etc. You can pilot the entire platform, and when you’re ready to scale, Stacklok’s got the added capabilities and expert team ready!</td>
