Connecting coding agents to a live desktop workbench with MCP

Description and use

MCP integration in Termexo enables coding agents to interact with the workspace in real time, automatically connecting to terminals and managing tasks without manual prompt updates.

Problem

A coding agent can change a repository while remaining unaware of the test running in another terminal or the tasks already recorded in your workbench.

Outcome

The integration test confirmed that the MCP SDK can perform a stdio handshake with the released Windows application, discover 19 tools, and query an isolated desktop workspace. An automatically connected Codex task terminal successfully called workspace_list and received the test workspace. Grok, OpenCode 2.0.15, and Antigravity also established connections, while Rust tests covered Claude configuration merging.

Workflow

• Install Termexo v0.10.10 and enable the MCP server in Settings → AI Control.
• Create a workspace for a local repository and keep the Termexo desktop open.
• Start a new agent terminal and restart existing processes to load the new configuration.
• Ask the agent to call workspace_list via termexo‑desktop and verify the tool call and workspace.
• Identify a test terminal and ask the agent to read its output.
• Create a draft task with a project, goal and acceptance criteria and inspect it.
• Execute the task using the agent and verify terminal_write and task_execute success.
• Review output, task state and resulting files before accepting the work.
• Disable the server or automatic connection and apply settings to remove Termexo‑owned entries while preserving other services.
• Use external clients with the generated JSON or TOML if they support Streamable HTTP and Bearer authentication.
• Evaluate concrete operations before extending the workflow.

Termexo, an MIT‑licensed Windows workbench for coding terminals. Version 0.10.10 exposes 19 local MCP tools and adds automatic connections for new Claude Code, Codex, OpenCode, Grok Build and Antigravity terminals launched by the application.

The official MCP SDK completed the stdio handshake against the released Windows application, discovered 19 tools and queried an isolated desktop workspace.

After the initial query, identify one test terminal and ask the agent to read its output. Then try creating a draft task with a project, goal and acceptance criteria you can inspect.
