Public surface of an active MCP client.

Properties

Property	Modifier	Type	Description	Defined in
collisionStrategy	readonly	CollisionStrategy	Per-client default collision strategy.	packages/mcp/src/client/types.ts:356
id	readonly	string	Stable identifier - derived from the transport.	packages/mcp/src/client/types.ts:350
priority?	readonly	number	Per-client priority value used by the 'priority' strategy.	packages/mcp/src/client/types.ts:358
resumable	readonly	boolean	Deprecated Alias of sessionIdPresent - same value, misleading name.	packages/mcp/src/client/types.ts:369
serverIdentity	readonly	ServerIdentity	Server identity descriptor consumed by the tool-registry resolver.	packages/mcp/src/client/types.ts:354
serverInfo	readonly	{ name: string; version: string; }	Server-advertised information from the initialize handshake.	packages/mcp/src/client/types.ts:352
serverInfo.name	readonly	string	-	packages/mcp/src/client/types.ts:352
serverInfo.version	readonly	string	-	packages/mcp/src/client/types.ts:352
sessionIdPresent	readonly	boolean	Whether the Streamable HTTP server assigned an Mcp-Session-Id at initialize time (MC-9). A session id means stateful routing - it is NOT a replay guarantee: per the Streamable HTTP spec, event replay is the SERVER's responsibility, and the SDK transport already auto-reconnects with Last-Event-ID when the server supports it.	packages/mcp/src/client/types.ts:367

readResource()

readResource(uri, opts?): Promise<MCPResourceContent>;

Defined in: packages/mcp/src/client/types.ts:385

First content item of the resource. mcp-skills-11: a multi-content response (one URI can yield several items) is truncated to the FIRST item - a WARN + counter fire when that happens; use readResourceContents for the full array.

Returns

Promise&lt;MCPResourceContent&gt;

---

readResourceContents()

Defined in: packages/mcp/src/client/types.ts:387

Every content item of the resource (mcp-skills-11).

Parameters

Parameter	Type
uri	string
opts?	{ signal?: AbortSignal; }
opts.signal?	AbortSignal

Returns

Promise&lt;readonly MCPResourceContent[]&gt;

---

Defined in: packages/mcp/src/client/types.ts:396

Parameters

Parameter	Type
opts?	MCPToToolsOptions

Returns

Promise<readonly Tool&lt;unknown, unknown, unknown&gt;[]>
