Connect to LM Studio

LM Studio 0.3.6+ supports MCP servers in its built-in agentic chat interface. Connect V5 to give any local model access to all 34 GTM tools.

Prerequisites

  • LM Studio 0.3.6 or later (free)
  • A V5 bearer token — get one from your admin: POST /admin/tokens/issue

Setup

1. Open MCP settings

In LM Studio:
  1. Open Settings (gear icon)
  2. Navigate to Extensions → Model Context Protocol
  3. Click Add Server

2. Configure V5

Click Save.

3. Verify

In LM Studio chat with any model, switch to Agentic mode and ask:
The model should list V5’s 34 tools.

Choosing models for GTM work

V5 works with any model in LM Studio, but tool calling accuracy varies: For production GTM work with real data, ai_invoke through the V5 gateway is recommended over local models — it routes to the right cloud model automatically.

Troubleshooting

Server shows as “disconnected”
LM Studio may not support SNI on some versions. Ensure you’re on LM Studio 0.3.6+. Check the LM Studio logs: View → Output → select MCP. Model doesn’t use tools
Not all models support tool use. Switch to a model with “Instruct” or “Tool” in the name. Function-calling support is required.
