Jeremiah Lowin	704b74b3ab	Update tests for the removed sampling and roots server API	2026-07-26 14:38:26 -04:00
Jeremiah Lowin	6fce4e538f	Move task subsystem to fastmcp-tasks package, disconnect SEP-1686 wire from core ... Engine modules (keys, context snapshot, docket lifespan, worker CLI, client handles) move intact; SEP-1686 wire modules park in _legacy_wire for adaptation to SEP-2663. Core keeps task=True declaration on tools only and raises at serve time until the tasks extension is registered. Co-Authored-By: Claude <noreply@anthropic.com>	2026-07-21 21:51:45 -04:00
Jeremiah Lowin	5f428aaced	Merge remote-tracking branch 'origin/main' into feature/client-auto-default	2026-07-20 17:53:27 -04:00
Jeremiah Lowin	57bbc9859e	Surface resource, prompt, and proxy errors on the modern protocol era (#4579) ... Three defects hidden by tests pinned to the handshake era, where a raw exception reaches the wire as str(exc). At 2026-07-28 the runner masks anything that is not an MCPError/ValidationError as "Internal server error". - _on_read_resource / _on_get_prompt now translate FastMCPError through to_mcp_error, mirroring _on_call_tool. Masking is unchanged. - FastMCPProxy registers a server/discover handler so upstream instructions reach modern clients; on_initialize only fires for the handshake. - ProxyProvider's list methods normalize transport failures into MCPError.	2026-07-20 17:52:12 -04:00
Jeremiah Lowin	d2ac7ed3d2	Default fastmcp.Client to mode="auto"; surface extensions=/result_claims= ... Client negotiates the newest mutual protocol era by default (probe server/discover, fall back to the initialize handshake). ProxyClient and the inspect utility explicitly pin the handshake era so proxy forwarding and server_info reads are unchanged. SSE and multi-server config transports are legacy-only. extensions= and result_claims= (SEP-2133) are thin passthroughs to the SDK session.	2026-07-19 21:22:49 -04:00
Jeremiah Lowin	13b9ab80ab	Use a single fastmcp import style in protocol-era tests	2026-07-06 22:06:22 -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
