• src/tools/nv-search-people.ts:7-107 (handler)

  Primary implementation of the 'nv_search_people' tool: NvSearchPeopleTool class defining name, operationName, Zod input schema for validation, detailed MCP inputSchema, and getTool() method for tool metadata.

  export class NvSearchPeopleTool extends OperationTool<TNvSearchPeopleParams, unknown> {
    public override readonly name = 'nv_search_people';
    public override readonly operationName = OPERATION_NAME.nvSearchPeople;
    protected override readonly schema = z.object({
      term: z.string().optional(),
      limit: z.number().min(1).max(2500).optional(),
      filter: z
        .object({
          firstName: z.string().optional(),
          lastName: z.string().optional(),
          position: z.string().optional(),

• src/linked-api-tools.ts:35-66 (registration)

  Registration of the nv_search_people tool: NvSearchPeopleTool is instantiated (line 59) and added to the LinkedApiTools collection alongside other tools.

  this.tools = [

    new GetConversationTool(progressCallback),
    new CheckConnectionStatusTool(progressCallback),
    new RetrieveConnectionsTool(progressCallback),

• src/utils/linked-api-tool.ts:36-58 (handler)

  Base handler logic shared by OperationTool subclasses like NvSearchPeopleTool: the execute method locates the LinkedIn API operation by operationName and invokes it via executeWithProgress.

  export abstract class OperationTool<TParams, TResult> extends LinkedApiTool<TParams, TResult> {
    public abstract readonly operationName: TOperationName;
  
    public override execute({
      linkedapi,
      args,
      workflowTimeout,
      progressToken,
    }: {
      linkedapi: LinkedApi;
      args: TParams;
      workflowTimeout: number;
      progressToken?: string | number;
    }): Promise<TMappedResponse<TResult>> {
      const operation = linkedapi.operations.find(
        (operation) => operation.operationName === this.operationName,
      )! as Operation<TParams, TResult>;
      return executeWithProgress(this.progressCallback, operation, workflowTimeout, {
        params: args,
        progressToken,
      });
    }
  }
