Jeremiah Lowin	6a6fdcb2bb	Repoint tests and examples off removed deprecations ... Replaces FastMCP.as_proxy() helper calls with create_proxy(), rewrites the mount() as_proxy=/prefix= kwarg tests to plain mount() (the params are gone), and deletes deprecation-only tests for as_proxy() and remove_tool().	2026-07-07 07:53:11 -04:00
Jeremiah Lowin	14373cc60b	Repoint examples off removed shim paths	2026-07-07 07:53:10 -04:00
Jeremiah Lowin	e5d9d1f17d	Remove deprecated FastMCP server methods for 4.0 ... Removes deprecations that shipped replacements in 3.0: - FastMCP.as_proxy() classmethod -> create_proxy() - import_server() -> mount() - mount(prefix=) -> namespace= - mount(as_proxy=) -> now meaningless; mounts always invoke lifespan/middleware - add_tool_transformation() -> add_transform(ToolTransform({...})) - remove_tool_transformation() -> pure no-op that warned callers it had no effect; removed entirely - FastMCP.remove_tool() -> mcp.local_provider.remove_tool() Also drops the now-unused URI_PATTERN/re import and FastMCPDeprecationWarning import. The _REMOVED_KWARGS TypeError shim is retained.	2026-07-07 07:53:10 -04:00

Jeremiah Lowin	36cbef6813	Remove no-op sse_read_timeout param from StreamableHttpTransport ... Tier 2 aggressive-window removal: the parameter was a deprecated no-op on the streamable-HTTP transport (the SDK v2 client no longer supports it). SSETransport still accepts sse_read_timeout.	2026-07-07 07:53:10 -04:00
Jeremiah Lowin	d74f7b5996	Remove deprecated PromptToolMiddleware / ResourceToolMiddleware (3.1) ... Use the PromptsAsTools / ResourcesAsTools transforms instead. The non-deprecated ToolInjectionMiddleware base class is retained.	2026-07-07 07:53:10 -04:00
Jeremiah Lowin	d1c51ea4db	Remove deprecated fastmcp.server.apps / server.app shims (3.2) ... Tier 2 aggressive-window removal: these shims were deprecated in 3.2, a shorter deprecation window than the usual policy. Canonical imports are fastmcp.apps / fastmcp.FastMCPApp.	2026-07-07 07:53:10 -04:00

Jeremiah Lowin	77131edc00	Don't era-gate server-side sampling handlers on modern connections ... The era-gate blocked every ctx.sample/sample_step on a 2026-07-28 connection, but a server-configured sampling handler answers server-side without the client back-channel. Gate only when the request would hit the removed client path; force the handler path (client_available=False) on modern so "fallback" goes straight to the handler instead of a bare client-attempt failure.	2026-07-06 21:49:18 -04:00
