Implementation Reference

• 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(), locations: z.array(z.string()).optional(), industries: z.array(z.string()).optional(), currentCompanies: z.array(z.string()).optional(), previousCompanies: z.array(z.string()).optional(), schools: z.array(z.string()).optional(), yearsOfExperiences: z.array(z.string()).optional(), }) .optional(), }); public override getTool(): Tool { return { name: this.name, description: 'Allows you to search people in Sales Navigator applying various filtering criteria. (nv.searchPeople action).', inputSchema: { type: 'object', properties: { term: { type: 'string', description: 'Optional. Keyword or phrase to search.', }, limit: { type: 'number', description: 'Optional. Number of search results to return. Defaults to 25, with a maximum value of 2500.', }, filter: { type: 'object', description: 'Optional. Object that specifies filtering criteria for people. When multiple filter fields are specified, they are combined using AND logic.', properties: { firstName: { type: 'string', description: 'Optional.

Matches if person currently works at any of the listed companies.', items: { type: 'string' }, }, previousCompanies: { type: 'array', description: 'Optional. Array of company names. Matches if person previously worked at any of the listed companies.', items: { type: 'string' }, }, schools: { type: 'array', description: 'Optional. Array of institution names. Matches if person currently attends or previously attended any of the listed institutions.', items: { type: 'string' }, }, yearsOfExperiences: { type: 'array', description: "Optional. Array of enums representing professional experience. Matches if person's experience falls within any of the listed ranges.", items: { type: 'string', enum: ['lessThanOne', 'oneToTwo', 'threeToFive', 'sixToTen', 'moreThanTen'], }, }, }, }, }, }, }; } }
• 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 = [ // Standard tools new SendMessageTool(progressCallback), new GetConversationTool(progressCallback), new CheckConnectionStatusTool(progressCallback), new RetrieveConnectionsTool(progressCallback), new SendConnectionRequestTool(progressCallback), new WithdrawConnectionRequestTool(progressCallback), new RetrievePendingRequestsTool(progressCallback), new RemoveConnectionTool(progressCallback), new SearchCompaniesTool(progressCallback), new SearchPeopleTool(progressCallback), new FetchCompanyTool(progressCallback), new FetchPersonTool(progressCallback), new FetchPostTool(progressCallback), new ReactToPostTool(progressCallback), new CommentOnPostTool(progressCallback), new CreatePostTool(progressCallback), new RetrieveSSITool(progressCallback), new RetrievePerformanceTool(progressCallback), // Sales Navigator tools new NvSendMessageTool(progressCallback), new NvGetConversationTool(progressCallback), new NvSearchCompaniesTool(progressCallback), new NvSearchPeopleTool(progressCallback), new NvFetchCompanyTool(progressCallback), new NvFetchPersonTool(progressCallback), // Other tools new ExecuteCustomWorkflowTool(progressCallback), new GetWorkflowResultTool(progressCallback), new GetApiUsageTool(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, }); } }
