• src/linked-api-tools.ts:31-67 (registration)

  Registration of SearchPeopleTool in the LinkedApiTools class constructor, where it is instantiated and added to the array of available tools.
  export class LinkedApiTools { public readonly tools: ReadonlyArray<LinkedApiTool<unknown, unknown>>; constructor(progressCallback: (progress: LinkedApiProgressNotification) => void) { 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), ]; }

  The SearchPeopleTool class defines the tool name 'search_people', schema for validation, MCP tool definition via getTool(), and delegates execution to the base OperationTool using operationName 'searchPeople' from linkedapi-node.
  export class SearchPeopleTool extends OperationTool<TSearchPeopleParams, unknown> { public override readonly name = 'search_people'; public override readonly operationName = OPERATION_NAME.searchPeople; protected override readonly schema = z.object({ term: z.string().optional(), limit: z.number().min(1).max(1000).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(), }) .optional(), }); public override getTool(): Tool { return { name: this.name, description: 'Allows you to search people applying various filtering criteria (st.searchPeople action).', inputSchema: { type: 'object', properties: { term: { type: 'string', description: 'Optional.

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

  Base OperationTool class providing the core execute method for all operation-based tools, including search_people. It locates the specific operation by name and executes it with progress tracking.
  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, }); } }
• src/tools/search-people.ts:10-25 (schema)

  Zod schema defining the input parameters for the search_people tool, matching TSearchPeopleParams from linkedapi-node.
  protected override readonly schema = z.object({ term: z.string().optional(), limit: z.number().min(1).max(1000).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(), }) .optional(), });
