@​modelcontextprotocol/server-legacy@​2.1.0

Patch Changes

• Updated dependencies [dcc0102]:
  • @​modelcontextprotocol/core@​2.1.0

@​modelcontextprotocol/server@​2.1.0

Minor Changes

• #1624 6032170 Thanks @​SamMorrowDrums! - Add request-time OAuth scope challenges for tools, resources, resource templates, and prompts. Each primitive's scopeChallenge callback receives the parsed request and verified authentication info, then either continues or returns the exact scope set for an insufficient_scope response. requireScopes provides a small helper for static all-of checks.

  createMcpHandler and Streamable HTTP transports return HTTP 403 with an insufficient_scope challenge before handler execution or SSE setup. The preflight is active whenever a registered primitive carries a scopeChallenge callback — there is no handler- or transport-level configuration. The challenge's WWW-Authenticate header is built by the same formatter as the bearer-auth 401/403 answers, and its resource_metadata parameter is derived from the verified AuthInfo: requireBearerAuth / verifyBearerToken now stamp their configured resourceMetadataUrl onto the AuthInfo they return (new optional AuthInfo.resourceMetadataUrl field), with a fallback to the well-known location for an HTTP(S) RFC 8707 resource identifier; the parameter is omitted when neither is available.

Patch Changes

• #2726 6fa4227 Thanks @​LuckTerence! - SdkError and SdkHttpError accept standard ErrorOptions as an optional fourth constructor argument and forward it to Error, so a wrapped error is reachable through the standard Error.cause chain. Version-negotiation probe failures (SdkErrorCode.EraNegotiationFailed) now use it: the underlying TypeError: fetch failed and the DNS or socket error beneath it surface via error.cause, so pino, Sentry, and util.inspect render ENOTFOUND / ECONNREFUSED / ETIMEDOUT instead of stopping at the SdkError (#2657). The previous error.data.cause slot is still populated for compatibility but is deprecated and slated for removal; read error.cause instead.

• #2654 03842cd Thanks @​pshah19! - Treat request id 0 as a real id. Two guards tested a RequestId for truthiness, so the legal JSON-RPC ids 0 and '' were read as absent. Id 0 is not a corner case: the outbound request counter is zero-based, so it is the first id every peer assigns, which on the server→client leg is the first sampling/createMessage, elicitation/create, or roots/list a server sends.

  • notifications/cancelled carrying id 0 was ignored, and the in-flight handler ran to completion with its AbortSignal never fired.
  • A notification sent with relatedRequestId: 0 wrongly passed the debounce gate (for methods opted into debouncedNotificationMethods). Because the pending set is keyed by method alone, a second such notification in the same tick was silently dropped rather than sent.

  Absent is now the only value that means "no id".

• #2668 3e90449 Thanks @​KKonstantinov! - Stop sending notifications/cancelled for the initialize handshake. The spec is explicit that a client MUST NOT attempt to cancel its initialize request, but the outbound cancel path fired for any in-flight request: aborting the AbortSignal passed to connect(), or letting the handshake hit its timeout, put a forbidden cancellation on the wire naming the initialize request id.

  The local behaviour is unchanged — the caller's promise still rejects with the same abort/timeout error, and connect() still tears the connection down. Only the wire notification is suppressed. Every other method keeps the existing cancellation path.

• #2698 7b781ed Thanks @​maxisbey! - Read Streamable HTTP request bodies with a size limit. Every SDK-owned body read — WebStandardStreamableHTTPServerTransport (and the Node transport built on it), createMcpHandler, toNodeHandler, and createMcpHonoApp's JSON pre-parse — now stops at 4 MiB by default (the limit the legacy SSE transport already uses; the Express adapter and stdio bound their reads too) and answers 413 Payload Too Large before anything is parsed. toWebRequest (when it reads the Node stream itself) now rejects once the body exceeds the limit with an error whose name is 'RequestBodyTooLargeError' and status is 413, and toNodeHandler answers that with 413; hand-wired callers of toWebRequest should handle the rejection or pass a pre-parsed body, and isLegacyRequest reports such a request as non-legacy
