WHOOP MCP Server

Instructions

Implementation Reference

• src/whoop-api.ts:96-99 (handler)

  Core handler function that performs the HTTP GET request to the Whoop API to retrieve recovery data for the specified cycle ID.

  async getRecoveryForCycle(cycleId: number): Promise<WhoopRecovery[]> {
    const response = await this.client.get(`/cycle/${cycleId}/recovery`);
    return response.data;
  }

• src/mcp-server.ts:143-156 (registration)

  Tool registration in MCP server including name, description, and input schema validation.

  {
    name: 'whoop-get-recovery-for-cycle',
    description: 'Get recovery data for a specific cycle',
    inputSchema: {
      type: 'object',
      properties: {
        cycleId: {
          type: 'number',
          description: 'ID of the cycle to get recovery data for',
        },
      },
      required: ['cycleId'],
    },
  },

• src/mcp-server.ts:403-416 (handler)

  MCP tool request handler that validates arguments, delegates to WhoopApiClient, and formats response as MCP content.

  case 'whoop-get-recovery-for-cycle': {
    if (!args || typeof args.cycleId !== 'number') {
      throw new Error('cycleId is required and must be a number');
    }
    const result = await this.whoopClient.getRecoveryForCycle(args.cycleId);
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(result, null, 2),
        },
      ],
    };
  }
