Claude Code

To configure the MCP Server in Claude Code’s VS Code Extension, create a file named .mcp.json in the root directory of your project, with the following content:

When using DVT IDE VS Code extension from marketplace:

{
    "mcpServers": {
        "dvt": {
            "type": "stdio",
            "command": "/bin/bash",
            "args": [
                "-c",
                "$DVT_HOME/platform/<os>-<arch>/bin/dvt_mcp.sh connect"
            ],
            "env": {
                "DVT_HOME": "<extensions_dir>/amiq.dvt-<version>-<os>-<arch>/dvt_home"
            }
        }
    }
}

When using DVT IDE VSCodium from a kit distribution:

{
    "mcpServers": {
        "dvt": {
            "type": "stdio",
            "command": "/bin/bash",
            "args": [
                "-c",
                "$DVT_HOME/bin/dvt_mcp.sh connect"
            ],
            "env": {
                "DVT_HOME": "path/to/dvt_home"
            }
        }
    }
}

Alternatively, you can configure the MCP Server using Claude Code CLI:

When using DVT IDE VS Code extension from marketplace:

claude mcp add --env DVT_HOME='<extensions_dir>/amiq.dvt-<version>-<os>-<arch>/dvt_home' --transport stdio dvt -- /bin/bash -c '$DVT_HOME/platform/<os>-<arch>/bin/dvt_mcp.sh connect'

When using DVT IDE VSCodium from a kit distribution:

claude mcp add --env DVT_HOME='path/to/dvt_home' --transport stdio dvt -- /bin/bash -c '$DVT_HOME/bin/dvt_mcp.sh connect'

Note

The methods above will enable access to the MCP Server only for the current DVT project. If you want to enable the MCP Server for all projects, either add the above server configuration in the ~/.claude.json file or use the claude mcp add --scope user <other_args> command.

After creating the JSON file (or using the claude mcp add command), follow these steps:

Open the Claude Code chat and use the /Manage MCP Server command.
Select Continue in Terminal.
When prompted, enable the MCP Server.
Select Refresh and continue in the Claude Code chat.
Reload the VSCode window to apply changes.

Note

Mainstream MCP hosts limit the environment of the MCP Server subprocess. Ensure that DVT_HOME and other necessary environment variables are properly set in the configuration.
