MCP codemode exposure no longer lists tools, tool counts, or server instructions in the codemode description. Servers are listed by name and an optional mcp.json description; scripts find tools with searchTools() and read instructions with describeNamespace(). codemode-deferred is an alias for codemode. refs #10212

/**
|
|
* Codemode, Tool Search, and MCP
|
|
*
|
|
* The CLI loads `codemode`, `tool_search`, and MCP as built-in extensions. SDK sessions add
|
|
* them to the resource loader's extension factories.
|
|
*
|
|
* `codemode` and `tool_search` are registered inactive. Enable them through the `defaultTools` setting
|
|
* (`tools` would also restrict the session to the named tools, which hides MCP tools), or let the
|
|
* MCP extension activate them: `codemode` for servers with `codemode` exposure, `tool_search` for
|
|
* servers with `deferred` exposure.
