Claude Code desktop
On this page
Use a local Code session in the Claude desktop app when you want the agent to work with workspace files. Desktop chat and Code sessions are different surfaces.

- Open the project in the app’s Code tab as a local session.
- Add or manage the server through Connectors, or use the project
.mcp.jsondefinition below. - Save the definition and start a new Code session.
- Verify
owlmeansis connected before asking it to modify source.
{
"mcpServers": {
"owlmeans": {
"command": "npx",
"args": ["-y", "@owlmeans/viable-mcp@latest", "--harness", "claude-code"]
}
}
}
Desktop local Code sessions can read project MCP configuration. If the same server is defined in several supported locations, avoid keeping conflicting definitions. The standalone Claude Code CLI does not automatically read desktop-chat configuration. See the official desktop guide.
For a hosted-only chat connection, follow Claude chat.
Check the connection
- Complete OwlMeans browser sign-in when requested.
- Ask the agent to call
describe_platformandsession_status. - Verify the intended project, workspace and inference mode.
- Ask it to inspect or install the project harness.
- Start a small generation or story workflow.
The examples use a local target. Add --target, cloud as separate arguments for a hosted project. Add --llm, local for delegated inference only when the connected coding agent will handle tasks. Mode selection explains the effects and costs.
Keep access tokens out of committed configuration. Restart the client after changing the server settings. If a tool is absent, inspect the connected server’s tool list and troubleshoot.
