get_spend_limits

Instructions

Implementation Reference

• src/tools/getSpendLimits.ts:33-51 (handler)

  Executes the get_spend_limits tool: validates params, calls Brex API, returns formatted JSON response.

  registerToolHandler("get_spend_limits", async (request: ToolCallRequest) => {
    try {
      const params = validateParams(request.params.arguments);
      const client = getBrexClient();
      const apiParams: SpendLimitListParams = {
        limit: params.limit,
        cursor: params.cursor,
        parent_budget_id: params.parent_budget_id,
        status: params.status,
        member_user_id: params.member_user_id
      };
      const resp = await client.getSpendLimits(apiParams);
      const items = Array.isArray(resp.items) ? resp.items : [];
      return { content: [{ type: "text", text: JSON.stringify({ spend_limits: items, meta: { count: items.length, next_cursor: resp.next_cursor } }, null, 2) }] };
    } catch (error) {
      logError(`Error in get_spend_limits: ${error instanceof Error ? error.message : String(error)}`);
      throw error;
    }
  });

• src/tools/index.ts:109-122 (schema)

  JSON schema for get_spend_limits tool inputs in the listTools handler response.

  {
    name: "get_spend_limits",
    description: "List spend limits (read-only). Example: {\"limit\":10,\"status\":\"ACTIVE\"}",
    inputSchema: {
      type: "object",
      properties: {
        limit: { type: "number" },
        cursor: { type: "string" },
        parent_budget_id: { type: "string" },
        status: { type: "string", enum: ["ACTIVE","ARCHIVED"] },
        member_user_id: { type: "string" }
      }
    }
  },

• src/tools/getSpendLimits.ts:32-52 (registration)

  Registers the get_spend_limits tool handler using registerToolHandler.

  export function registerGetSpendLimits(_server: Server): void {
    registerToolHandler("get_spend_limits", async (request: ToolCallRequest) => {
      try {
        const params = validateParams(request.params.arguments);
        const client = getBrexClient();
        const apiParams: SpendLimitListParams = {
          limit: params.limit,
          cursor: params.cursor,
          parent_budget_id: params.parent_budget_id,
          status: params.status,
          member_user_id: params.member_user_id
        };
        const resp = await client.getSpendLimits(apiParams);
        const items = Array.isArray(resp.items) ? resp.items : [];
        return { content: [{ type: "text", text: JSON.stringify({ spend_limits: items, meta: { count: items.length, next_cursor: resp.next_cursor } }, null, 2) }] };
      } catch (error) {
        logError(`Error in get_spend_limits: ${error instanceof Error ? error.message : String(error)}`);
        throw error;
      }
    });
  }

• src/tools/getSpendLimits.ts:21-30 (helper)

  Validates and parses input parameters for the get_spend_limits tool.

  function validateParams(input: unknown): GetSpendLimitsParams {
    const raw = (input || {}) as Record<string, unknown>;
    const out: GetSpendLimitsParams = {};
    if (raw.limit !== undefined) { const n = parseInt(String(raw.limit), 10); if (isNaN(n) || n <= 0 || n > 100) throw new Error("Invalid limit (1..100)"); out.limit = n; }
    if (raw.cursor !== undefined) out.cursor = String(raw.cursor);
    if (raw.parent_budget_id !== undefined) out.parent_budget_id = String(raw.parent_budget_id);
    if (raw.status !== undefined) out.status = String(raw.status) as SpendLimitStatus;
    if (raw.member_user_id !== undefined) out.member_user_id = String(raw.member_user_id);
    return out;
  }

• src/tools/getSpendLimits.ts:13-19 (schema)

  TypeScript interface defining typed parameters for get_spend_limits.

  interface GetSpendLimitsParams {
    limit?: number;
    cursor?: string;
    parent_budget_id?: string;
    status?: SpendLimitStatus;
    member_user_id?: string;
  }
