pi auth login <provider> logs in from the shell without starting a
session, like pi mcp login. Account sign-in is the default and takes
the provider's browser method; when the provider has another method,
it prints a hint to rerun with --no-browser. --no-browser skips the
browser method and uses the other one, such as device code, asking
only when there are several. --api-key saves an API key instead and
cannot be combined with --no-browser. After logging in, it fetches the
provider's model catalog, and for Radius it points the Radius MCP
server in the global mcp.json at the login without asking.
pi auth logout <provider> removes the stored credentials like /logout
and succeeds when nothing is stored. For MCP servers that use provider
credentials, pi mcp login and logout now refer to these commands
instead of /login and /logout.
/login shares the check for the Radius MCP server entry and the web
URL helpers with the new command.
Servers with auth.provider, such as Radius, were reported as needing sign-in because the shell command sent no token. pi mcp now reads and refreshes the provider's /login token, and its hints and login/logout point to /login <provider>.
oauth.clientRegistration defaults to auto: pi's Client ID Metadata Document
when the authorization server supports it for public clients, otherwise
dynamic client registration. Registered clients stay in use. pi mcp add
gains --oauth-client-registration.

Adds oauth.clientName (and pi mcp add --oauth-client-name) to set the
client_name sent during dynamic client registration. Defaults to pi.

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
This adds codemode and MCP support to pi. Codemode (packages/codemode) runs
model-written JavaScript in a QuickJS wasm VM inside a worker. From there the
script calls pi's tools as async functions, uses a per-session store, and can
read the model catalog and run classifiers. The codemode tool in coding-agent
is compatible with Codex's exec tool, and codemode.mode works like Codex's
tool modes (on or only). Large results are written to a JSON temp file. MCP
(packages/mcp) is a standalone client for stdio and streamable HTTP servers,
with OAuth.
The core only gets general mechanisms; codemode, tool_search and MCP are
built-in extensions that use them. Other extensions can replace these
built-ins. Tools declare an exposure: direct, model-only, codemode, deferred
or hidden. prepareLoadout() lets an orchestrating tool change which tool
declarations the model sees. ctx.executeTool() runs nested calls through
validation and the tool_call/tool_result hooks. Those calls emit events with
parentToolCallId and are recorded as bounded nestedCalls on the parent
result, which compaction and HTML export use. Tools can also return
structuredContent with an outputSchema, and can report errors with isError
instead of throwing. MCP servers come from mcp.json (global, or per project
after the project is trusted) or from pi.registerMcpServer(). They are
managed with /mcp and pi mcp list|login|logout, and their runtimes load on
first use.
