* Refactor CodeMode to use CatalogTransform base class
Removes the duplicate ContextVar bypass pattern in favor of the shared
CatalogTransform machinery. Also fixes a pre-existing bug where
`from __future__ import annotations` caused NameError for Annotated
in nested function scopes at runtime.
* Remove redundant _get_visible_tools wrapper in CodeMode
* Rewrite CodeMode docs with proper motivation and structure
* Fix type narrowing in collision test
* Stop unwrapping tool results in CodeMode's call_tool
call_tool() inside execute blocks now returns structured content as-is,
preserving the {"result": value} wrapping. This means the output schema
shown in search results accurately describes what call_tool() returns,
so LLMs can trust the schema when writing code.
Also adds examples/code_mode/ with a server and narrated client demo.
* Simplify call_tool return type: dict | str
* Fix example client to unwrap structured results
* Let server resolve tool versions instead of pinning first match
* Rewrite CodeMode docs to match current behavior
* Rename optional extra from monty to code-mode

Fix description of "FastMCP Constructor Parameters": Remove parameters `on_duplicate_tools`, `on_duplicate_resources` and `on_duplicate_prompts`, which are no longer accepted by FastMCP(). Add the new parameter `on_duplicate` and its description.
* feat: Add search transforms for tool discovery
RegexSearchTransform and BM25SearchTransform collapse large tool
catalogs into a search interface so LLMs discover tools on demand
instead of receiving the full listing.
* chore: Update SDK documentation
* fix: call_tool recursion guard, atomic BM25 rebuild, hash includes descriptions
* Extract CatalogTransform base class for catalog-aware transforms
Transforms that replace list_tools() with synthetic components (like
search) need to read the real catalog at call time without triggering
their own replacement logic. CatalogTransform handles the re-entrant
bypass via per-instance ContextVar, exposing transform_tools() as the
subclass hook and get_tool_catalog() for catalog access.
* Add search transform examples for regex and BM25
* Add README for search transform examples
* Polish search example clients with rich output
* Remove hardcoded tool counts from search example subtitles
* Clarify that review bot feedback should be evaluated on its merits
* Expand search transform docs with proper hierarchy

The `key` parameter was removed from `add_resource()` in the 2.x era and no longer exists in the implementation. Removes all references and the "Custom Resource Keys" section from both the current and v2 docs.

* Add consent binding cookie to prevent confused deputy attacks (GHSA-rww4-4w9c-7733)
The OAuthProxy's consent page verified user intent but didn't bind the
consenting browser to the IdP callback. An attacker could intercept the
upstream authorization URL after consent and send it to a victim, whose
browser would complete the flow without having the consent cookie.
This adds a signed consent binding cookie set during consent approval
(both manual and auto-approve paths) and verified in the IdP callback
handler. A different browser won't have this cookie and gets a 403.
* Use startswith for URL assertion in consent binding test
* Store consent bindings as per-transaction map to support parallel flows
* Only accept __Host- consent binding cookie on HTTPS
* chore: Update SDK documentation
