MCPToolSource

Defined in: packages/ai/src/activities/chat/mcp/types.ts:25

Minimal structural shape that chat({ mcp }) needs from an MCP client.

@tanstack/ai-mcp's MCPClient and MCPClients satisfy this interface by shape — the core @tanstack/ai package does NOT import @tanstack/ai-mcp (ai-mcp depends on ai, not the reverse).

Properties#

close#

close: () => Promise<void>;

Defined in: packages/ai/src/activities/chat/mcp/types.ts:30

Returns#

Promise<void>

readResource?#

optional readResource?: (uri) => Promise<McpResourceReadResult>;

Defined in: packages/ai/src/activities/chat/mcp/types.ts:38

Reads an MCP resource by URI. Used by the chat manager to eagerly fetch ui:// resource widgets (MCP Apps) after a tool result resolves.

Optional — sources that do not serve ui:// resources need not implement this method. ai-mcp's MCPClient satisfies this structurally.

Parameters#

uri#

string

Returns#

Promise<McpResourceReadResult>

tools#

tools: (options?) => Promise<AnyServerTool[]>;

Defined in: packages/ai/src/activities/chat/mcp/types.ts:29

Parameters#

lazy?#

boolean

Returns#

Promise<AnyServerTool[]>
