12   * Build the dynamic MCP config + allowed tool names. Mirror of

14   * `allowedTools` so they bypass the normal permission prompt — the package's
15   * `request_access` handles approval for the whole session.
16   *
17   * The MCP layer isn't ceremony: the API backend detects `mcp__computer-use__*`
18   * tool names and emits a CU availability hint into the system prompt
19   * (COMPUTER_USE_MCP_AVAILABILITY_HINT in the anthropic repo). Built-in tools
20   * with different names wouldn't trigger it. Cowork uses the same names for the
21   * same reason (apps/desktop/src/main/local-agent-mode/systemPrompt.ts:314).
